react-native-google-fit

A React Native bridge module for interacting with Google Fit

Changelog:

0.0.9   - Weights Save Support
        - Refactor methods to be compatible with react-native-apple-healthkit module
        - Remove 'moment.js' dependency

0.0.8   - Weights Samples support

0.0.1   - 0.0.7 Initial builds

Getting started

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

Mostly automatic installation

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

then, in MainApplication.java, you need to pass MainActivity.activity to the module:

new GoogleFitPackage(MainActivity.activity),

Manual installation

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(MainActivity.activity), to the list returned by the getPackages() method

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')
   

USAGE

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

2. Authorize:

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

3. 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!');
               } 
           });
       }
   }

4. 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);
});

5. 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';
   });

6. Other methods:

GoogleFit.observeSteps(callback); //On Step Changed Event

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

PLANS / TODO

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