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:

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

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

PLANS / TODO
