    A flexible React Native module for Google Fit

    Why is it flexible?

    For example, you can query history data using Builder-Pattern of DataReadRequest like Android native way!~

    const HOUR_MS = 1000 * 60 * 60;
    // Setting a start and end date using a range of 1 week before this moment.
    const endTime =;
    const startTime = endTime - HOUR_MS * 24 * 7;
    const readRequest = new DataReadRequest.Builder()
        .aggregate_dataType(DataType.TYPE_STEP_COUNT_DELTA, DataType.AGGREGATE_STEP_COUNT_DELTA)
        .bucketByTime(1, TimeUnit.DAYS)
        .setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
    const result = await Fitness.History.readData(readRequest);

    Quite awesome, isn't it?

    • Support Promise (not callback) for API result

    Getting started

    Install NPM package

    $ npm install react-native-google-fitness --save

    Automatic native library link

    $ react-native link react-native-google-fitness

    or Manual native library link
    1. Append the following lines to android/settings.gradle:

      include ':react-native-google-fitness'
      project(':react-native-google-fitness').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-google-fitness/android')
    2. Insert the following lines inside the dependencies block in android/app/build.gradle:

      compile project(':react-native-google-fitness')
    3. Open up android/app/src/main/java/.../

      • Add import com.ybrain.rn.GoogleFitnessPackage; to the imports at the top of the file
      • Add new GoogleFitnessPackage(), to the list returned by the getPackages() method.

    Android SDK setup

    In order to build Android source code, you'll need following SDK setups

       Android Support Repository
       Android Support Library
       Google Play services
       Google Repository
       Google Play APK Expansion Library

    Enable Google Fitness API for your application

    In order for your app to communicate properly with the Google Fitness API Follow steps in

    1. Enable Google Fit API in your Google API Console. Also you need to generate new client ID for your app and provide both debug and release SHA keys. Another step is to configure the consent screen, etc.

    2. Provide the SHA1 sum of the certificate used for signing your application to Google. This will enable the GoogleFit plugin to communicate with the Fit application in each smartphone where the application is installed.

    Example application

    Example application is included in this repository.

    To run example

    Because Metro-bundler of React-native doesn't support symbolic link dependency, you need workaround as following. (See details in

    1. Link library root to global
      react-native-activity-tracker$ npm link

    2. Install node_modules of example
      react-native-activity-tracker/example$ npm install

    3. Link global library
      react-native-activity-tracker/example$ npm link react-native-activity-tracker

    4. Now you can start RN node server
      npm start
