react-native-google-fitness

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 = Date.now();
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)
    .build();

const result = await Fitness.History.readData(readRequest);

Quite awesome, isn't it?

More features

• Support Flow type checking (IDE auto-complete)
• 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/.../MainApplication.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 https://developers.google.com/fit/android/get-api-key

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 https://medium.com/@andrewdurber/using-react-native-with-symbolic-links-89a8f42a6563)

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
