Capacitor Google Analytics

A Capacitor plugin that enables the new data streams in Google Analytics and Firebase analytics.

⚠️ This plugin is still under development. Use at your own risk. I am actively developing it. Check back for updates or feel free to contribute.

Special Thanks

A special thanks to philmerrell as a starting point for this plugin. It appears that they are no longer able to maintain their plugin https://github.com/philmerrell/capacitor-firebase-analytics this is why I create this.

Compatability

Currently compatible with Android. Will be compatible with iOS and Web/PWA on or about 10/29/2019.

Getting Started

Create Google/Firebase Analytics Account

To get started visit https://analytics.google.com.

Create new account.
Set Account Details.
Select Apps and Web.
Select Next
After the account is created you should see "Setup data stream to start collecting data".

Android Setup

Google Analytics Setup

Select Android app.
Add package name.
Add app name.
Agree to terms.
Register app.
After registering the app Google Analytics will configure a Firebase/Google Cloud project associated with your app.
Once this is complete select next.
Download the google-services.json

Ionic 4 Setup

Add the Capacitor Google Analytics plugin to your project.
```
npm install capacitor-google-analytics
```

Add the plugin to any components or services you want to expose the the methods.

import { CapacitorGoogleAnalytics } from 'capacitor-google-analytics';
 
@Component({
selector: 'app-root',
templateUrl: 'app.component.html',
styleUrls: ['app.component.scss']
})
export class AppComponent {
 
    constructor() {}
 
    public async logEvent() {
        try {
            const event = { someLabel: 'someValue' };
            const didLogEvent = await CapacitorGoogleAnalytics.logEvent('someEvent', event)
        } catch (err) {
            throw new Error(err)
        }
    }
 
}

Build your project.
```
ionic build --platform=android
```
Add Android to your project.
```
ionic cap add android
```
Sync Android with your project (This will actually run on step three. If you already added Android you can skip three and just run this.)
```
ionic cap sync android
```
Open your project in Android Studio
```
ionic cap open android
```

Android Studio Setup

Once you are in Android Studio switch to Project view.
In the Project level build.gradle add the following to dependencies
```
classpath 'com.google.gms:google-services:4.2.0'
```
a) In the App level build.gradle add the following to dependencies
```
implementation 'com.google.firebase:firebase-core:17.0.0'
```

b) Ionic 4 notes. If you're using Ionic 4 change the snippets versions to:

implementation 'com.google.firebase:firebase-core:16.0.7'
implementation 'com.google.firebase:firebase-analytics:16.3.0'

In the same file add the following to the bottom of the file.
```
apply plugin: 'com.google.gms.google-services'
```
Sync Project

Xcode Setup

Once you are in Xcode select the Project Navigator Icon
Expand App then right click the App Folder beneath the first App
Select Add Files to "App"
Select the GoogleService-Info.plist file and then select App below.
You should now be able to build the app as normal.

Web/PWA Setup

Documentation coming soon. In order to get web working add a firebaseConfig in the AppComponent and call the initializeApp method. You can find the config values after you create a web project in Google Analytics then visiting Firebase -> Project Setup.

I will provide more detailed information soon. Below is an example.

import { CapacitorGoogleAnalytics } from 'capacitor-google-analytics';
 
@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.scss']
})
export class AppComponent {
 
  private firebaseConfig: any = {
    apiKey: "xxxx",
    authDomain: "xxxx",
    databaseURL: "xxxx",
    projectId: "xxxx",
    storageBucket: "xxxx",
    messagingSenderId: "xxxx",
    appId: "xxxx",
    measurementId: "xxxx"
  };
 
  constructor() {}
 
  async initializeApp() {
    CapacitorGoogleAnalytics.initializeApp({ config: this.firebaseConfig });
  }
