Getting started

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

Enable Google Fitness API for your application

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

Mostly Automatic installation

$ 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)

Manual installation

• 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

• 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')
  

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

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

USAGE

• import GoogleFit from 'react-native-google-fit';

• Authorize:

        GoogleFit.authorizeFit();
        GoogleFit.onAuthorize((result) => {
             //console.log(result);
             dispatch('AUTH SUCCESS');
        });

• Retrieve Steps For Period

GoogleFit.getSteps(dayStart, dayEnd);

REDUX example

   let retrieveDailySteps = () => {
       return async (dispatch) => {
           let todayStart = "2017-01-01T00:00:17.971Z"; //ISO Time String
           let dayEnd = "2017-01-01T23:59:17.971Z"; //ISO Time String
           await GoogleFit.getSteps(todayStart, dayEnd);
           await GoogleFit.observeHistory((results) => {
               if (results.length > 0) {
                   console.log(results[0].steps);
                   dispatch('SUCCESSFULLY GOT DAILY STEPS!');
               }
           });
       }
   }

• Retrieve Weights

let 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);
});

• Save Weights

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

• Other methods:

observeSteps(callback); //On Step Changed Event

unsucscribeListeners(); //Put into componentWillUnmount() method to prevent leaks

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)

PLANS / TODO

• support of all Google Fit activity types
• code refactoring
• optimization
