Basic integration

We will describe the steps to integrate the Adjust SDK into your React Native project. You can use any text editor or IDE for React Native development. There are no assumptions made regarding development environment.

Get the SDK

First, download the library from npm:

$ npm install react-native-adjust --save

Then you must install the native dependencies. You can use react-native cli tool to add native dependencies automatically and then continue the directions below depending on your target OS.

$ react-native link

Or if you use CocoaPods for iOS, add the following to your Podfile and run pod install afterwards:

pod 'react-native-adjust', :path => '../node_modules/react-native-adjust'

For iOS, you don't need to do anything else.

For Android, you may need to check if Adjust package was added to the native module's package list.

Go to your app's MainApplication.java class. It should be located in ./android/app/src/main/java/[your app]/MainApplication.java
There is a method called getPackages() that looks like this by default:

@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
      new MainReactPackage()
  );
}

After adding Adjust SDK via npm and running react-native link command, Adjust package should be added automatically to this list and it should look something like this:

import com.adjust.nativemodule.AdjustPackage;
 
// ... 
 
@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new AdjustPackage()
  );
}

In case that the line new AdjustPackage() was not added automatically, you'll have to add it to the list of packages by yourself like described above. Also, don't forget to add the import statement on top of the MainApplication.java file:

import com.adjust.nativemodule.AdjustPackage;

Integrate the SDK into your app

You should use the following import statement on top of your .js file

import { Adjust, AdjustEvent, AdjustConfig } from 'react-native-adjust';

In your App.js file, add the following code to initialize the Adjust SDK:

constructor(props) {
    super(props);
    const adjustConfig = new AdjustConfig("{YourAppToken}", AdjustConfig.EnvironmentSandbox);
    Adjust.create(adjustConfig);
}
 
componentWillUnmount() {
  Adjust.componentWillUnmount();
}

Replace {YourAppToken} with your app token. You can find this in your Adjust dashboard.

Depending on whether you build your app for testing or for production, you must set the environment with one of these values:

AdjustConfig.EnvironmentSandbox
AdjustConfig.EnvironmentProduction

Important: This value should be set to AdjustConfig.EnvironmentSandbox if and only if you or someone else is testing your app. Make sure to set the environment to AdjustConfig.EnvironmentProduction just before you publish the app. Set it back to AdjustConfig.EnvironmentSandbox when you start developing and testing it again.

We use this environment to distinguish between real traffic and test traffic from test devices. It is very important that you keep this value meaningful at all times!

Adjust logging

You can increase or decrease the amount of logs you see in tests by calling setLogLevel on your AdjustConfig instance with one of the following parameters:

adjustConfig.setLogLevel(AdjustConfig.LogLevelVerbose);   // enable all logging
adjustConfig.setLogLevel(AdjustConfig.LogLevelDebug);     // enable more logging
adjustConfig.setLogLevel(AdjustConfig.LogLevelInfo);      // the default
adjustConfig.setLogLevel(AdjustConfig.LogLevelWarn);      // disable info logging
adjustConfig.setLogLevel(AdjustConfig.LogLevelError);     // disable warnings as well
adjustConfig.setLogLevel(AdjustConfig.LogLevelAssert);    // disable errors as well
adjustConfig.setLogLevel(AdjustConfig.LogLevelSuppress);  // disable all logging

Adjust project settings

Once the Adjust SDK has been added to your app, certain tweaks are going to be performed so that the Adjust SDK can work properly. Below you can find a description of every additional thing that the Adjust SDK performs after you've added it to your app and what needs to be done by you in order for Adjust SDK to work properly.

Android permissions

The Adjust SDK by default adds two permissions to your app's AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

The INTERNET permission might be needed by our SDK at any point in time. The ACCESS_WIFI_STATE permission is needed by the Adjust SDK if your app is not targeting the Google Play Store and doesn't use Google Play Services. If you are targeting the Google Play Store and you are using Google Play Services, the Adjust SDK doesn't need this permission and, if you don't need it anywhere else in your app, you can remove it.

Google Play Services

Since August 1, 2014, apps in the Google Play Store must use the Google Advertising ID to uniquely identify devices. To allow the Adjust SDK to use the Google Advertising ID, you must integrate Google Play Services.

In order to do this, open your app's build.gradle file and find the dependencies block. Add the following line:

compile 'com.google.android.gms:play-services-analytics:10.0.1'

Note: The version of the Google Play Services library that you're using is not relevant to the Adjust SDK, as long as the analytics part of the library is present in your app. In the example above, we just used the most recent version of the library at the time of writing.

To check whether the analytics part of the Google Play Services library has been successfully added to your app so that the Adjust SDK can read it properly, you should start your app by configuring the SDK to run in sandbox mode and set the log level to verbose. After that, track a session or some events in your app and observe the list of parameters in the verbose logs which are being read once the session or event has been tracked. If you see a parameter called gps_adid in there, you have successfully added the analytics part of the Google Play Services library to your app and our SDK is reading the necessary information from it.

In case you encounter any issue with attempts to read Google Advertising Identifier, feel free to open an issue in our Github repository or write an email to support@adjust.com.

Proguard settings

If you are using Proguard, add these lines to your Proguard file:

-keep public class com.adjust.sdk.** { *; }
-keep class com.google.android.gms.common.ConnectionResult {
    int SUCCESS;
}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient {
    com.google.android.gms.ads.identifier.AdvertisingIdClient$Info getAdvertisingIdInfo(android.content.Context);
}
-keep class com.google.android.gms.ads.identifier.AdvertisingIdClient$Info {
    java.lang.String getId();
    boolean isLimitAdTrackingEnabled();
}
-keep public class com.android.installreferrer.** { *; }

Install referrer

In order to correctly attribute an install of your Android app to its source, Adjust needs information about the install referrer. This can be obtained by using the Google Play Referrer API or by catching the Google Play Store intent with a broadcast receiver.

Important: The Google Play Referrer API is newly introduced by Google with the express purpose of providing a more reliable and secure way of obtaining install referrer information and to aid attribution providers in the fight against click injection. It is strongly advised that you support this in your application. The Google Play Store intent is a less secure way of obtaining install referrer information. It will continue to exist in parallel with the new Google Play Referrer API temporarily, but it is set to be deprecated in future.

Google Play Referrer API

In order to support this, add the following line to your app's build.gradle file:

compile 'com.android.installreferrer:installreferrer:1.0'

installreferrer library is part of Google Maven repository, so in order to be able to build your app, you need to add Google Maven repository to your app's build.gradle file if you haven't added it already:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

Also, make sure that you have paid attention to the Proguard settings chapter and that you have added all the rules mentioned in it, especially the one needed for this feature:

-keep public class com.android.installreferrer.** { *; }

This feature is supported if you are using the Adjust SDK v4.12.0 or above.

Google Play Store intent

The Google Play Store INSTALL_REFERRER intent should be captured with a broadcast receiver. The Adjust install referrer broadcast receiver is added to your app by default. For more information, you can check our native Android SDK README. You can see this in the AndroidManifest.xml file which is part of our React Native plugin:

<receiver android:name="com.adjust.sdk.AdjustReferrerReceiver" 
          android:exported="true" >
    <intent-filter>
        <action android:name="com.android.vending.INSTALL_REFERRER" />
    </intent-filter>
</receiver>

Please bear in mind that, if you are using your own broadcast receiver which handles the INSTALL_REFERRER intent, you don't need to add the Adjust broadcast receiver to your manifest file. You can remove it, but inside your own receiver add the call to the Adjust broadcast receiver as described in our Android guide.

iOS frameworks

Select your project in the Project Navigator. In the left hand side of the main view, select your target. In the tab Build Phases, expand the group Link Binary with Libraries. On the bottom of that section click on the + button. Select the AdSupport.framework and click the Add button. Unless you are using tvOS, repeat the same steps to add the iAd.framework and CoreTelephony.framework. Change the Status of both frameworks to Optional. Adjust SDK uses these frameworks with following purpose:

iAd.framework - in case you are running iAd campaigns
AdSupport.framework - for reading iOS Advertising Id (IDFA)
CoreTelephony.framework - for reading MCC and MNC information

If you are not running any iAd campaigns, you can feel free to remove the iAd.framework dependency.

Additional features

You can take advantage of the following features once the Adjust SDK is integrated into your project.

Event tracking

You can use Adjust to track all kinds of events. Let's say you want to track every tap on a button. Simply create a new event token in your dashboard. Let's say that event token is abc123. You can add the following line in your button’s click handler method to track the click:

var adjustEvent = new AdjustEvent("abc123");
Adjust.trackEvent(adjustEvent);

Revenue tracking

If your users can generate revenue by tapping on advertisements or making In-App Purchases, then you can track those revenues with events. Let's say a tap is worth €0.01. You could track the revenue event like this:

var adjustEvent = new AdjustEvent("abc123");
 
adjustEvent.setRevenue(0.01, "EUR");
 
Adjust.trackEvent(adjustEvent);

When you set a currency token, Adjust will automatically convert the incoming revenues into a reporting revenue of your choice. Read more about currency conversion here.

Revenue deduplication

You can also add an optional transaction ID to avoid tracking duplicate revenues. The last ten transaction IDs are remembered, and revenue events with duplicate transaction IDs are skipped. This is especially useful for In-App Purchase tracking. You can see an example below.

If you want to track in-app purchases, please make sure to call the trackEvent only if the transaction is finished and an item is purchased. That way you can avoid tracking revenue that is not actually being generated.

var adjustEvent = new AdjustEvent("abc123");
 
adjustEvent.setRevenue(0.01, "EUR");
adjustEvent.setTransactionId("{YourTransactionId}");
 
Adjust.trackEvent(adjustEvent);

Note: Transaction ID is the iOS term, unique identifier for successfully finished Android In-App-Purchases is named Order ID.

In-app purchase verification

In-app purchase verification can be conducted through the React Native Purchase SDK which is currently in development and will soon be made publicly available. For more information, please contact support@adjust.com.

Callback parameters

You can also register a callback URL for that event in your dashboard and we will send a GET request to that URL whenever the event gets tracked. In that case you can also put some key-value pairs in an object and pass it to the trackEvent method. We will then append these named parameters to your callback URL.

For example, suppose you have registered the URL http://www.adjust.com/callback for your event with event token abc123 and execute the following lines:

var adjustEvent = new AdjustEvent("abc123");
 
adjustEvent.addCallbackParameter("key", "value");
adjustEvent.addCallbackParameter("foo", "bar");
 
Adjust.trackEvent(adjustEvent);

In that case we would track the event and send a request to:

http://www.adjust.com/callback?key=value&foo=bar

It should be mentioned that we support a variety of placeholders like {idfa} for iOS or {gps_adid} for Android that can be used as parameter values. In the resulting callback the {idfa} placeholder would be replaced with the ID for Advertisers of the current device for iOS and the {gps_adid} would be replaced with the Google Advertising ID of the current device for Android. Also note that we don't store any of your custom parameters, but only append them to your callbacks. If you haven't registered a callback for an event, these parameters won't even be read.

You can read more about using URL callbacks, including a full list of available values, in our callbacks guide.

Note: Both parameters in this method must be strings. If either of the passed parameters is not a string, the key-value pair will not be added to the parameters list.

Partner parameters

Similarly to the callback parameters mentioned above, you can also add parameters that Adjust will transmit to the network partners of your choice. You can activate these networks in your Adjust dashboard.

This works similarly to the callback parameters mentioned above, but can be added by calling the addPartnerParameter method on your AdjustEvent instance.

var adjustEvent = new AdjustEvent("abc123");
 
adjustEvent.addPartnerParameter("key", "value");
adjustEvent.addPartnerParameter("foo", "bar");
 
Adjust.trackEvent(adjustEvent);

You can read more about special partners and networks in our guide to special partners.

Note: Both parameters in this method must be strings. If either of the passed parameters is not a string, the key-value pair will not be added to the parameters list.

Callback identifier

You can also add custom string identifier to each event you want to track. This identifier will later be reported in event success and/or event failure callbacks to enable you to keep track on which event was successfully tracked or not. You can set this identifier by calling the setCallbackId method on your AdjustEvent instance:

var adjustEvent = new AdjustEvent("abc123");
 
adjustEvent.setCallbackId("Your-Custom-Id");
 
Adjust.trackEvent(adjustEvent);

Session parameters

Some parameters are saved to be sent in every event and session of the Adjust SDK. Once you have added any of these parameters, you don't need to add them every time, since they will be saved locally. If you add the same parameter twice, there will be no effect.

These session parameters can be called before the Adjust SDK is launched to make sure they are sent even on install. If you need to send them with an install, but can only obtain the needed values after launch, it's possible to delay the first launch of the Adjust SDK to allow this behaviour.

Session callback parameters

The same callback parameters that are registered for events can be also saved to be sent in every event or session of the Adjust SDK.

The session callback parameters have a similar interface of the event callback parameters. Instead of adding the key and its value to an event, it's added through a call to method addSessionCallbackParameter of the Adjust instance:

Adjust.addSessionCallbackParameter("foo", "bar");

The session callback parameters will be merged with the callback parameters and added to an event. The callback parameters added to an event have precedence over the session callback parameters. Meaning that, when adding a callback parameter to an event with the same key to one added from the session, the value that prevails is the callback parameter added to the event.

Note: Both parameters in this method must be strings. If either of the passed parameters is not a string, the key-value pair will not be added to the parameters list.

It's possible to remove a specific session callback parameter by passing the desiring key to the method removeSessionCallbackParameter of the Adjust instance:

Adjust.removeSessionCallbackParameter("foo");

If you wish to remove all key and values from the session callback parameters, you can reset it with the method resetSessionCallbackParameters of the Adjust instance:

Adjust.resetSessionCallbackParameters();

Session partner parameters

In the same way that there are session callback parameters that are sent for every event or session of the Adjust SDK, there are also session partner parameters.

These will be transmitted to network partners, for the integrations that have been activated in your Adjust dashboard.

The session partner parameters have a similar interface to the event partner parameters. Instead of adding the key and its value to an event, it's added through a call to method addSessionPartnerParameter of the Adjust instance:

Adjust.addSessionPartnerParameter("foo", "bar");

The session partner parameters will be merged with the partner parameters and added to an event. The partner parameters added to an event have precedence over the session partner parameters. Meaning that, when adding a partner parameter to an event with the same key to one added from the session, the value that prevails is the partner parameter added to the event.

Note: Both parameters in this method must be strings. If either of the passed parameters is not a string, the key-value pair will not be added to the parameters list.

It's possible to remove a specific session partner parameter by passing the desiring key to the method removeSessionPartnerParameter of the Adjust instance:

Adjust.removeSessionPartnerParameter("foo");

If you wish to remove all keys and values from the session partner parameters, you can reset it with the method resetSessionPartnerParameters of the Adjust instance:

Adjust.resetSessionPartnerParameters();

Delay start

Delaying the start of the Adjust SDK allows your app some time to obtain session parameters, such as unique identifiers, to be sent on install.

Set the initial delay time in seconds with the setDelayStart field of the AdjustConfig instance:

adjustConfig.setDelayStart(5.5);

In this case this will make the Adjust SDK not send the initial install session and any event created for 5.5 seconds. After this time is expired or if you call sendFirstPackages() of the Adjust instance in the meanwhile, every session parameter will be added to the delayed install session and events and the Adjust SDK will resume as usual.

The maximum delay start time of the Adjust SDK is 10 seconds.

Attribution callback

You can register a listener to be notified of tracker attribution changes. Due to the different sources considered for attribution, this information cannot be provided synchronously. The simplest way is to create a single anonymous listener which is going to be called each time your user's attribution value changes:

With the AdjustConfig instance, before starting the SDK, add the anonymous listener:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setAttributionCallbackListener(function(attribution) {
    // Printing all attribution properties.
    console.log("Attribution changed!");
    console.log(attribution.trackerToken);
    console.log(attribution.trackerName);
    console.log(attribution.network);
    console.log(attribution.campaign);
    console.log(attribution.adgroup);
    console.log(attribution.creative);
    console.log(attribution.clickLabel);
    console.log(attribution.adid);
});
 
Adjust.create(adjustConfig);

Within the listener function you have access to the attribution parameters. Here is a quick summary of its properties:

trackerToken the tracker token of the current attribution.
trackerName the tracker name of the current attribution.
network the network grouping level of the current attribution.
campaign the campaign grouping level of the current attribution.
adgroup the ad group grouping level of the current attribution.
creative the creative grouping level of the current attribution.
clickLabel the click label of the current attribution.
adid the Adjust device identifier.

Please make sure to consider our applicable attribution data policies.

Session and event callbacks

You can register a callback to be notified of successful and failed tracked events and/or sessions.

Follow the same steps as for attribution callback to implement the following callback function for successfully tracked events:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setEventTrackingSucceededCallbackListener(function(eventSuccess) {
    // Printing all event success properties.
    console.log("Event tracking succeeded!");
    console.log(eventSuccess.message);
    console.log(eventSuccess.timestamp);
    console.log(eventSuccess.eventToken);
    console.log(eventSuccess.callbackId);
    console.log(eventSuccess.adid);
    console.log(eventSuccess.jsonResponse);
});
 
Adjust.create(adjustConfig);

The following callback function for failed tracked events:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setEventTrackingFailedCallbackListener(function(eventFailure) {
    // Printing all event failure properties.
    console.log("Event tracking failed!");
    console.log(eventFailure.message);
    console.log(eventFailure.timestamp);
    console.log(eventFailure.eventToken);
    console.log(eventFailure.callbackId);
    console.log(eventFailure.adid);
    console.log(eventFailure.willRetry);
    console.log(eventFailure.jsonResponse);
});
 
Adjust.create(adjustConfig);

For successfully tracked sessions:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setSessionTrackingSucceededCallbackListener(function(sessionSuccess) {
    // Printing all session success properties.
    console.log("Session tracking succeeded!");
    console.log(sessionSuccess.message);
    console.log(sessionSuccess.timestamp);
    console.log(sessionSuccess.adid);
    console.log(sessionSuccess.jsonResponse);
});
 
Adjust.create(adjustConfig);

And for failed tracked sessions:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setSessionTrackingFailedCallbackListener(function(sessionFailure) {
    // Printing all session failure properties.
    console.log("Session tracking failed!");
    console.log(sessionFailure.message);
    console.log(sessionFailure.timestamp);
    console.log(sessionFailure.adid);
    console.log(sessionFailure.willRetry);
    console.log(sessionFailure.jsonResponse);
});
 
Adjust.create(adjustConfig);

The callback functions will be called after the SDK tries to send a package to the server. Within the callback you have access to a response data object specifically for the callback. Here is a quick summary of the session response data properties:

var message the message from the server or the error logged by the SDK.
var timestamp timestamp from the server.
var adid a unique device identifier provided by Adjust.
var jsonResponse the JSON object with the response from the server.

Both event response data objects contain:

var eventToken the event token, if the package tracked was an event.
var callbackId the custom defined callback ID set on event object.

And both event and session failed objects also contain:

var willRetry indicates there will be an attempt to resend the package at a later time.

Disable tracking

You can disable the Adjust SDK from tracking by invoking the method setEnabled of the Adjust instance with the enabled parameter as false. This setting is remembered between sessions, but it can only be activated after the first session.

Adjust.setEnabled(false);

You can verify if the Adjust SDK is currently active with the method isEnabled of the Adjust instance. It is always possible to activate the Adjust SDK by invoking setEnabled with the parameter set to true.

Offline mode

You can put the Adjust SDK in offline mode to suspend transmission to our servers while retaining tracked data to be sent later. When in offline mode, all information is saved in a file, so be careful not to trigger too many events while in offline mode.

You can activate offline mode by calling the method setOfflineMode of the Adjust instance with the parameter true.

Adjust.setOfflineMode(true);

Conversely, you can deactivate offline mode by calling setOfflineMode with false. When the Adjust SDK is put back in online mode, all saved information is send to our servers with the correct time information.

Unlike disabling tracking, this setting is not remembered between sessions. This means that the SDK is in online mode whenever it is started, even if the app was terminated in offline mode.

Event buffering

If your app makes heavy use of event tracking, you might want to delay some HTTP requests in order to send them in one batch every minute. You can enable event buffering with your AdjustConfig instance by calling setEventBufferingEnabled method:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setEventBufferingEnabled(true);
 
Adjust.create(adjustConfig);

GDPR right to be forgotten

In accordance with article 17 of the EU's General Data Protection Regulation (GDPR), you can notify Adjust when a user has exercised their right to be forgotten. Calling the following method will instruct the Adjust SDK to communicate the user's choice to be forgotten to the Adjust backend:

Adjust.gdprForgetMe();

Upon receiving this information, Adjust will erase the user's data and the Adjust SDK will stop tracking the user. No requests from this device will be sent to Adjust in the future.

Disable third-party sharing for specific users

You can now notify Adjust when a user has exercised their right to stop sharing their data with partners for marketing purposes, but has allowed it to be shared for statistics purposes.

Call the following method to instruct the Adjust SDK to communicate the user's choice to disable data sharing to the Adjust backend:

Adjust.disableThirdPartySharing();

Upon receiving this information, Adjust will block the sharing of that specific user's data to partners and the Adjust SDK will continue to work as usual.

SDK signature

An account manager must activate the Adjust SDK signature. Contact Adjust support (support@adjust.com) if you are interested in using this feature.

If the SDK signature has already been enabled on your account and you have access to App Secrets in your Adjust Dashboard, please use the method below to integrate the SDK signature into your app.

An App Secret is set by passing all secret parameters (secretId, info1, info2, info3, info4) to setAppSecret method of AdjustConfig instance:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setAppSecret(secretId, info1, info2, info3, info4);
 
Adjust.create(adjustConfig);

Background tracking

The default behaviour of the Adjust SDK is to pause sending HTTP requests while the app is in the background. You can change this in your AdjustConfig instance by calling setSendInBackground method:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setSendInBackground(true);
 
Adjust.create(adjustConfig);

If nothing is set, sending in background is disabled by default.

Device IDs

Certain services (such as Google Analytics) require you to coordinate device and client IDs in order to prevent duplicate reporting.

iOS advertising identifier

You can access the IDFA value of an iOS device by invoking the getIdfa method of the Adjust instance and passing it a callback that will get triggered once the IDFA value has been obtained by the native iOS SDK:

Adjust.getIdfa((idfa) => {
    console.log("IDFA = " + idfa);
});

Google Play Services advertising identifier

The Adjust SDK allows you to read the Google advertising identifier of the Android device on which your app is running. In order to do this, call the getGoogleAdId method of the Adjust instance and pass your callback as a parameter. Once obtained by the native Android SDK, you will receive the Google advertising identifier value in your callback method:

Adjust.getGoogleAdId((googleAdId) => {
    console.log("Google Ad Id = " + googleAdId);
});

Amazon advertising identifier

If you need to obtain the Amazon advertising ID, you can call the getAmazonAdId method of the Adjust instance and pass your callback as a parameter to which the Amazon advertising ID value will be sent once obtained:

Adjust.getAmazonAdId((amazonAdId) => {
    console.log("Amazon Ad Id = " + amazonAdId);
});

Adjust device identifier

For every device with your app installed on it, the Adjust backend generates a unique Adjust device identifier (adid). In order to obtain this identifier, call the getAdid method of the Adjust instance and pass your callback as a parameter to which the adid value will be sent once obtained:

Adjust.getAdid((adid) => {
    console.log("Adid = " + adid);
});

Note: Information about the adid is only available after an app installation has been tracked by the Adjust backend. From that moment on, the Adjust SDK has information about the device adid and you can access it with this method. So, it is not possible to access the adid value before the SDK has been initialized and installation of your app has been successfully tracked.

User attribution

This callback is triggered as described in the attribution callback section, providing you with information about a new attribution whenever it changes. If you want to access information about a user's current attribution status at any other time, you can make a call to the getAttribution method of the Adjust instance and pass your callback as a parameter to which the attribution value will be sent once obtained:

Adjust.getAttribution((attribution) => {
    console.log("Tracker token = " + attribution.trackerToken);
    console.log("Tracker name = " + attribution.trackerName);
    console.log("Network = " + attribution.network);
    console.log("Campaign = " + attribution.campaign);
    console.log("Adgroup = " + attribution.adgroup);
    console.log("Creative = " + attribution.creative);
    console.log("Click label = " + attribution.clickLabel);
    console.log("Adid = " + attribution.adid);
});

Note: Information about a user's current attribution status is only available after an app installation has been tracked by the Adjust backend and the attribution callback has been triggered. From that moment on, the Adjust SDK has information about a user's attribution status and you can access it with this method. So, it is not possible to access a user's attribution value before the SDK has been initialized and an attribution callback has been triggered.

Push token

To send us the push notification token, add the following call to Adjust whenever you get your token in the app or when it gets updated:

Adjust.setPushToken("YourPushNotificationToken");

Push tokens are used for Audience Builder and client callbacks, and they are required for the upcoming uninstall tracking feature.

Track additional device identifiers

If you are distributing your Android app outside of the Google Play Store and would like to track additional device identifiers (IMEI and MEID), you need to explicitly instruct the Adjust SDK to do so. You can do that by calling the setReadMobileEquipmentIdentity method of the AdjustConfig instance. The Adjust SDK does not collect these identifiers by default.

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setReadMobileEquipmentIdentity(true);
 
Adjust.create(adjustConfig);

You will also need to add the READ_PHONE_STATE permission to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

In order to use this feature, additional steps are required within your Adjust Dashboard. For more information, please contact your dedicated account manager or write an email to support@adjust.com.

Pre-installed trackers

If you want to use the Adjust SDK to recognize users that found your app pre-installed on their device, follow these steps.

Create a new tracker in your dashboard.

Open your app delegate and add set the default tracker of your AdjustConfig instance:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setDefaultTracker("{TrackerToken}");
 
Adjust.create(adjustConfig);

Replace {TrackerToken} with the tracker token you created in step 2. Please note that the dashboard displays a tracker URL (including http://app.adjust.com/). In your source code, you should specify only the six-character token and not the entire URL.

Build and run your app. You should see a line like the following in the app's log output:
```
Default tracker: 'abc123'
```

Deep linking

If you are using the Adjust tracker URL with an option to deep link into your app from the URL, there is the possibility to get info about the deep link URL and its content. Hitting the URL can happen when the user has your app already installed (standard deep linking scenario) or if they don't have the app on their device (deferred deep linking scenario).

Standard deep linking scenario

To support deep linking in Android, the app's AndroidManifest.xml file will need to be modified. Please refer to this page of our Android SDK for the needed modifications to AndroidManifest.xml.

To support deep linking in iOS 8 or earlier, the app's Info.plist file will need to be modified. Please refer to this page of our iOS SDK for the needed modifications to Info.plist.

To support deep linking in iOS 9 or later, your app would have to handle Universal Links. Please refer to this page of our iOS SDK for the needed modifications.

After that, refer to this page of the React Native offical docs for instructions on how to support both platforms and obtain deep link URL in your JavaScript code.

Deferred deep linking scenario

While deferred deep linking is not supported out of the box on Android and iOS, our Adjust SDK makes it possible.

In order to get info about the URL content in a deferred deep linking scenario, you should set a callback method on the AdjustConfig object which will receive one parameter where the content of the URL will be delivered. You should set this method on the config object by calling the method setDeferredDeeplinkCallbackListener:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setDeferredDeeplinkCallbackListener(function(deeplink) {
    console.log("Deferred deep link URL content: " + deeplink);
});
 
Adjust.create(adjustConfig);

In the deferred deep linking scenario, there is one additional setting which can be set on the AdjustConfig object. Once the Adjust SDK gets the deferred deep link info, we are offering you the possibility to choose whether our SDK should open this URL or not. You can choose to set this option by calling the setShouldLaunchDeeplink method on the config object:

var adjustConfig = new AdjustConfig(appToken, environment);
 
adjustConfig.setShouldLaunchDeeplink(true);
// or adjustConfig.setShouldLaunchDeeplink(false);
 
adjustConfig.setDeferredDeeplinkCallbackListener(function(deeplink) {
    console.log("Deferred deep link URL content: " + deeplink);
});
 
Adjust.create(adjustConfig);

If nothing is set, the Adjust SDK will always try to launch the URL by default.

Reattribution via deep links

Adjust enables you to run re-engagement campaigns by using deep links. For more information on this, please check our official docs.

If you are using this feature, in order for your user to be properly reattributed, you need to make one additional call to the Adjust SDK in your app. Once you have received deep link content information in your app, add a call to appWillOpenUrl method of the Adjust instance. By making this call, the Adjust SDK will try to find if there is any new attribution info inside of the deep link and if any, it will be sent to the Adjust backend. If your user should be reattributed due to a click on the Adjust tracker URL with deep link content in it, you will see the attribution callback in your app being triggered with new attribution info for this user.

Call to the appWillOpenUrl method in a React component would look like this:

componentDidMount() {
    Linking.addEventListener('url', this.handleDeepLink);
    Linking.getInitialURL().then((url) => {
        if (url) {
            this.handleDeepLink({ url });
        }
    })
}
 
componentWillUnmount() {
    Linking.removeEventListener('url', this.handleDeepLink);
}
 
handleDeepLink(event) {
    Adjust.appWillOpenUrl(event.url);
}
