A React Native bridge module for interacting with Google Fit

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

In order for your app to communicate properly with the Google Fitness API you need to 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.

More detailed info available at https://developers.google.com/fit/android/get-api-key

1. In order for the library to work correctly, you'll need following SDK setups:
   
   Android Support Repository
   Android Support Library
   Google Play services
   Google Repository
   Google Play APK Expansion Library
   
2. In order for your app to communicate properly with the Google Fitness API,
   you need to 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.

$ react-native link react-native-google-fit

then pass your package name to the module in MainApplication.java (google fit requires package name to save data)

new GoogleFitPackage(BuildConfig.APPLICATION_ID) Note: Do not change BuildConfig.APPLICATION_ID - it's a constant value.

1. Open up android/app/src/main/java/[...]/MainApplication.java

   • Add import com.reactnative.googlefit.GoogleFitPackage; to the imports at the top of the file
   • Add new GoogleFitPackage(BuildConfig.APPLICATION_ID), to the list returned by the getPackages() method. Note: Do not change BuildConfig.APPLICATION_ID - it's a constant value.

2. Append the following lines to android/settings.gradle:

   include ':react-native-google-fit'
   project(':react-native-google-fit').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-google-fit/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-google-fit')
   

1. import GoogleFit from 'react-native-google-fit';

2. Authorize:

   GoogleFit.onAuthorize(() => {
     dispatch('AUTH SUCCESS');
   });
   
   GoogleFit.onAuthorizeFailure(() => {
     dispatch('AUTH ERROR');
   });
   
   GoogleFit.authorize();
   
   // ...
   // Call when authorized
   GoogleFit.startRecording((callback) => {
     // Process data from Google Fit Recording API (no google fit app needed)
   });

3. Retrieve Steps For Period

   const options = {
     startDate: "2017-01-01T00:00:17.971Z", // required ISO8601Timestamp
     endDate: new Date().toISOString() // required ISO8601Timestamp
   };
   
   GoogleFit.getDailyStepCountSamples(options, (err, res) => {
     if (err) {
       throw err;
     }
   
     console.log("Daily steps >>>", res);
   });

Response:

[
  { source: "com.google.android.gms:estimated_steps", steps: [] },
  { source: "com.google.android.gms:merge_step_deltas", steps: [] },
  { source: "com.xiaomi.hm.health", steps: [] }
];

4. Retrieve Weights

   const opt = {
     unit: "pound", // required; default 'kg'
     startDate: "2017-01-01T00:00:17.971Z", // required
     endDate: new Date().toISOString(), // required
     ascending: false // optional; default false
   };
   
   GoogleFit.getWeightSamples(opt, (err, res) => {
     console.log(res);
   });

5. Retrieve Heights

   const opt = {
     startDate: "2017-01-01T00:00:17.971Z", // required
     endDate: new Date().toISOString(), // required
   };
   
   GoogleFit.getHeightSamples(opt, (err, res) => {
     console.log(res);
   });

6. Save Weights

   const opt = {
     value: 200,
     date: new Date().toISOString(),
     unit: "pound"
   };
   
   GoogleFit.saveWeight(opt, (err, res) => {
     if (err) throw "Cant save data to the Google Fit";
   });

7. Get all activities

     let options = {
       startDate: new Date(2018, 9, 17).valueOf(), // simply outputs the number of milliseconds since the Unix Epoch
       endDate: new Date(2018, 9, 18).valueOf()
     };
     GoogleFit.getActivitySamples(options, (err, res) => {
       console.log(err, res)
     });

   response:

    [ { 
     sourceName: 'Android',
     device: 'Android',
     sourceId: 'com.google.android.gms',
     calories: 764.189208984375,
     quantity: 6,
     end: 1539774300992,
     tracked: true,
     activityName: 'still',
     start: 1539727200000 },
   { sourceName: 'Android',
     device: 'Android',
     sourceId: 'com.google.android.gms',
     calories: 10.351096153259277,
     quantity: 138,
     end: 1539774486088,
     tracked: true,
     distance: 88.09545135498047,
     activityName: 'walking',
   }]

   Where:

   sourceName = device - 'Android' or 'Android Wear' string
   sourceId - return a value of dataSource.getAppPackageName(). For more info see: https://developers.google.com/fit/android/data-attribution
   start/end - timestamps of activity in format of milliseconds since the Unix Epoch
   tracked - bool flag, is this activity was entered by user or tracked by device. Detected by checking milliseconds of start/end timestamps. Since when user log activity in googleFit they can't set milliseconds
   distance(opt) - A distance in meters.
   activityName - string, equivalent one of these https://developers.google.com/fit/rest/v1/reference/activity-types 
   calories(opt) - double value of burned Calories in kcal.
   quantity(opt) - equivalent of steps number
   

   Note that optional parametrs are not presented in all activities - only where google fit return some results for this field. Like no distance for still activity.

8. Other methods:

   observeSteps(callback); // On Step Changed Event
   
   unsubscribeListeners(); // Put into componentWillUnmount() method to prevent leaks
   
   getDailyCalorieSamples(options, callback); // method to get calories per day
   
   getDailyDistanceSamples(options, callback); // method to get daily distance
   
   isAvailable(callback); // Checks is GoogleFit available for current account / installed on device
   
   isEnabled(callback); // Checks is permissions granted
   
   deleteWeight(options, callback); // method to delete weights by options (same as in save weights)
   
   openFit(); //method to open google fit app
   
   saveHeight(options, callback);
   
   deleteHeight(options, callback);
   
   deleteWeight(options, callback);
   
   disconnect(); // Closes the connection to Google Play services.
