react-native-samsung-health

React Native bridge module for interacting with Samsung Health

Installing it as a library in your main project

There are many ways to do this:

Do npm install --save git+https://github.com/cellihealth/react-native-samsung-health.git in your main project.

Link the library:

Add the following to android/settings.gradle:

include ':react-native-samsung-health'
project(':react-native-samsung-health').projectDir = new File(settingsDir, '../node_modules/react-native-samsung-health/android')

Add the following to android/app/build.gradle:

...

dependencies {
    ...
    compile project(':react-native-samsung-health')
}

Add the following to android/app/src/main/java/**/MainApplication.java:

package com.example;

import com.reactnative.samsunghealth.SamsungHealthPackage;  // add this for react-native-samsung-health

public class MainApplication extends Application implements ReactApplication {

    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new SamsungHealthPackage(BuildConfig.APPLICATION_ID)     // add this for react-native-samsung-health
        );
    }
}

Add permission in android/app/src/main/AndroidManifest.xml:

<application

<meta-data
  android:name="com.samsung.android.health.permission.read"
  android:value="com.samsung.health.step_count;com.samsung.shealth.step_daily_trend;com.samsung.health.weight" />

Simply import/require it by the name defined in your library's package.json:

import SamsungHealth from 'react-native-samsung-health';

SamsungHealth.authorize([SamsungHealth.STEP_COUNT], (err, res) => {
  if (res) {
    let opt = {};
    SamsungHealth.getDailyStepCountSamples(opt, (err, res) => {
      if (err) console.log(err);
      if (res) console.log(res);
    });
  } else console.log(err);
});

Methods

    distance: 1000
    duration: 1800

getWeightSamples

    weight: 65 // kilos
}]

getStepsDailyTrend

Aggregated de-duplicated step counts from all possible sources. Use this unless you know you want duplicate data from all devices via getDailyStepCountSamples.

SamsungHealth.getStepsDailyTrend({}, (err, res) => { console.log(res) });

[{
    hourly: [0, 20, 30, 0, ...] // An array of step counts per hour over 24 hours from startTime
    count: 207, // steps
    startTime: "2018-12-12T00:00:00.000Z" // UTC timestamp of the start of the day
}]

Modify/Build the Project in Android Studio

Start Android Studio and select File -> New -> Import Project and select the android folder of this package.
If you get a Plugin with id 'android-library' not found Error, install android support repository.
If you get asked to upgrade gradle to a new version, you can skip it.

Access Data without S Health partner app certification

If you want to test your app on your device but you don't have the Samsung app certification you'll see an error that looks like

java.lang.SecurityException: Denied to access by whitelist

this error is because to work with S Health you app must be certified, to prevent this error for local development you can enable the developer mode on the Samsun Healt app, go to

Settings -> About Samsung Health

and tap 10 times on the app version, the name of the version will then change to *(Developer Mode)* and you'll be able to access S Health data
