Info.plist

Add Health Kit permissions descriptions to your Info.plist file.

<key>NSHealthShareUsageDescription</key>
<string>We will use your health information to better track workouts.</string>

<key>NSHealthUpdateUsageDescription</key>
<string>We will update your health information to better track workouts.</string>

<key>NSHealthClinicalHealthRecordsShareUsageDescription</key>
<string>We will use your health information to better track  workouts.</string>

Android Setup

First of all you have to add the required health permissions to your "AndroidManifest.xml" file

<uses-permission android:name="android.permission.health.READ_SLEEP"/>
<uses-permission android:name="android.permission.health.READ_WEIGHT"/>
<uses-permission android:name="android.permission.health.READ_ACTIVE_CALORIES_BURNED"/>
<uses-permission android:name="android.permission.health.READ_BASAL_METABOLIC_RATE"/>
<uses-permission android:name="android.permission.health.READ_BLOOD_GLUCOSE"/>
<uses-permission android:name="android.permission.health.READ_BLOOD_PRESSURE"/>
<uses-permission android:name="android.permission.health.READ_BODY_FAT"/>
<uses-permission android:name="android.permission.health.READ_BONE_MASS"/>
<uses-permission android:name="android.permission.health.READ_EXERCISE"/>
<uses-permission android:name="android.permission.health.READ_DISTANCE"/>
<uses-permission android:name="android.permission.health.READ_ELEVATION_GAINED"/>
<uses-permission android:name="android.permission.health.READ_FLOORS_CLIMBED"/>
<uses-permission android:name="android.permission.health.READ_HEART_RATE"/>
<uses-permission android:name="android.permission.health.READ_HEART_RATE_VARIABILITY"/>
<uses-permission android:name="android.permission.health.READ_HEIGHT"/>
<uses-permission android:name="android.permission.health.READ_OXYGEN_SATURATION"/>
<uses-permission android:name="android.permission.health.READ_POWER"/>
<uses-permission android:name="android.permission.health.READ_RESPIRATORY_RATE"/>
<uses-permission android:name="android.permission.health.READ_RESTING_HEART_RATE"/>
<uses-permission android:name="android.permission.health.READ_SPEED"/>
<uses-permission android:name="android.permission.health.READ_STEPS"/>
<uses-permission android:name="android.permission.health.READ_TOTAL_CALORIES_BURNED"/>
<uses-permission android:name="android.permission.health.READ_BODY_TEMPERATURE"/>
<uses-permission android:name="android.permission.health.READ_BASAL_METABOLIC_RATE" />

2. Also add the following query in the node:

<queries>
    <package android:name="com.google.android.apps.healthdata" />
</queries>

3. As well as that you have to add intent filter to your activity definition so that you can request the permissions at runtime. This intent filter reference should be added under the node, mostly in the .

<intent-filter>
    <action android:name="androidx.health.ACTION_SHOW_PERMISSIONS_RATIONALE" />
</intent-filter>

*For Android 14 support you also need to add additional intent-filters:

<intent-filter>
  <action
          android:name="android.intent.action.VIEW_PERMISSION_USAGE"/>
  <category
          android:name="android.intent.category.HEALTH_PERMISSIONS"/>
</intent-filter>

4. For Android 14 support additional manifest element inside application tag

<activity-alias
        android:name="ViewPermissionUsageActivity"
        android:exported="true"
        android:targetActivity=".MainActivity"
        android:permission="android.permission.START_VIEW_PERMISSION_USAGE">
  <intent-filter>
    <action android:name="android.intent.action.VIEW_PERMISSION_USAGE" />
    <category android:name="android.intent.category.HEALTH_PERMISSIONS" />
  </intent-filter>
</activity-alias>

5. In case permissions handling is not working, this might be related to launch mode being singleTop. This might be not needed, but some apps faced problems when requesting permissions. If you face them, then you should try removing the following line:

android:launchMode="singleTop"

6. In case app is not building, it might be related to label replacement issue. In this case, you should add the following line to the tag:

tools:replace="android:label"

7. Since we are using closed source native Android SDK, separate repository is needed. Thus, add the following dependency into your android/builde.gradle file (it must be added both in repositories and allprojects node of repositories):

maven {
  url 'https://gitlab.com/api/v4/projects/43396247/packages/maven'
}

Check HealthConnect availability (Android Only)

Check if Health Connect installed on a device.

const isPackageInstalled = await Spike.isPackageInstalled();

Check HealthStore data availability (iOS Only)

Check if Health Store data available on a device.

const isAvailable = await Spike.isHealthDataAvailable();

Spike SDK usage

Start getting Spike data in 3 steps. All Spike SDK async method calls should be wrapped into try catch block.

1. Create Spike connection

To set up the Spike SDK create SpikeConnection instance with SpikeConnectionConfig object. From the 2.1.x version Spike SDK automatically manages connection persistance and restore connection if finds one with same appId, authToken and customerEndUserId. With each new connection creating call callbackUrl could be overridden. Provide SpikeLogger implementation to handle connection logs.

import Spike from 'react-native-spike-sdk-gfit';

const conn = await Spike.createConnection(
  {
    appId: 'my_app_id',
    authToken: 'my_app_access_token',
    customerEndUserId: 'my_user_id',
    callbackUrl: 'my_callback_url', // Optional, provides functionality to send data to webhook and use background deliveries.
  },
  logger // Optional, class which conforms to SpikeLogger interface
);

2. Permissions

Provide permissions to access iOS HealthKit and Android HealthConnect data. Spike SDK methods will check required permissions and request them if needed. Permission dialog may not be shown according on platform permissions rules.

// conn was created in the previous step

if (Platform.OS === 'android') {
  // Android methods should be called on connection instance
  const isGranted = await conn.checkPermissionsGranted(
    SpikeDataTypes.activitiesStream
  );
  if (!isGranted) {
    await conn.requestHealthPermissions(SpikeDataTypes.activitiesStream);
  }

  // Or request multiple permissions
  await conn.requestHealthPermissions([
    SpikeDataTypes.activitiesStream,
    SpikeDataTypes.steps,
  ]);
}

if (Platform.OS === 'ios') {
  // iOS method should be called on Spike class
  await Spike.ensurePermissionsAreGranted([
    SpikeDataTypes.activitiesStream,
    SpikeDataTypes.steps,
  ]); // Provide required Spike data types
}

3. Extract data

There are two ways to get Spike data: to your webhook or directly in your app. Extract data methods requires SpikeExtractConfig object, where date range can be provided optionally. By providing range greater than one day samples array of result object will be empty. The maximum permitted date range for iOS is 90 days, while for Android it's 30 days.

Extract data locally

According to the provided SpikeDataType result object may be different.

// conn was created in the previous step

// Extract steps data for today
const data = await conn.extractData({
  dataType: SpikeDataTypes.steps,
});

// OR you can provide same day
const today = new Date() // could be any day
const data = await conn.extractData({
    SpikeDataTypes.steps,
    from: today,
    to: today
});

// conn was created in the previous step

// Extract steps data for yesterday and today.
const today = new Date();
const yesterday = new Date();
yesterday.setDate(today.getDate() - 1);
const data = await conn.extractData({
  dataType: SpikeDataTypes.steps,
  from: yesterday,
  to: today,
});

Extract data to webhook

Ensure callbackUrl was provided to SpikeConnection, otherwise you will get SpikeCallbackURLNotProvidedException error. Method will return job information object.

// conn was created in the previous step

// Send today's steps data to webhook
const data = await conn.extractAndPostData({
  dataType: SpikeDataTypes.steps,
});

// OR you can provide same day
const today = new Date(); // could be any day
const data = await conn.extractAndPostData({
  dataType: SpikeDataTypes.steps,
  from: today,
  to: today,
});

// conn was created in the previous step

// Send yesterday's and today's steps data to webhook
const today = new Date();
const yesterday = new Date();
yesterday.setDate(today.getDate() - 1);
const data = await conn.extractAndPostData({
  dataType: SpikeDataTypes.steps,
  from: yesterday,
  to: today,
});

Background deliveries (iOS Only)

Background delivery enables asynchronous data delivery to the customer backend by means of webhooks. It enables data updates to be sent to the backend even when the application is hidden or closed. Background delivery is only supported on iOS devices at the moment. Background deliveries will send whole day data to the webhook.

Configure for background deliveries

Under your project Signing & Capabilities section enable Background Delivery for HealthKit. Call Spike configure methods on each app start to trigger background deliveries tasks. Add Spike initialization code to ios/<Project Name>/AppDelegate.mm file inside application:didFinishLaunchingWithOptions: method.

If you plan on supporting background delivery, you need to set up all observer queries in your app delegate. Spike SDK will do it by calling configure() method. Read more Receive Background Updates.

import <SpikeSDK/SpikeSDK-Swift.h>
...

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  ...
  [Spike configure];
  ...

}

Register connection for background deliveries

Ensure callbackUrl was provided to SpikeConnection, otherwise you will get SpikeCallbackURLNotProvidedException error. Provide required Spike Data types to enableBackgroundDelivery method, it could be called after connection is created.

await conn.enableBackgroundDelivery([
  SpikeDataTypes.activitiesSummary,
  SpikeDataTypes.steps,
]);

• If dataTypes is not empty, then a daemon task is started which will listen for data updates coming from the platform and send them via webhooks in the background; the operation is not compound and each method call will override enabled background data types list;

• If dataTypes parameter is empty or null, then background data delivery is stopped for this connection if it was enabled;

You can check if connection have active background deliveries listeners. If background delivery is not enabled, an empty set is returned.

const dataTypes = await conn.getBackgroundDeliveryDataTypes();

Logging

Internally, the React Native SDK supports logging on various levels to assist with troubleshooting. However, to avoid imposing additional third-party dependencies on library users, the SDK expects a concrete logging implementation to be provided externally. This can be done by implementing the SpikeLogger class and providing it when creating a connection.

Below is an example of how to implement a simple console logger.

class ConsoleLogger implements SpikeLogger {
  isDebugEnabled() {
    return true;
  }

  isInfoEnabled() {
    return true;
  }

  isErrorEnabled() {
    return true;
  }

  debug(connection: SpikeConnection, message: string) {
    console.log(`[SPIKE_DEBUG] ${message}`);
  }

  info(connection: SpikeConnection, message: string) {
    console.log(`[SPIKE_INFO] ${message}`);
  }

  error(connection: SpikeConnection, message: string) {
    console.log(`[SPIKE_ERROR] ${message}`);
  }
}

Spike SDK provides background delivery process logs. This can be done by implementing the SpikeBackgroundDeliveriesLogger class and providing it though connection's setListener method.

Below is an example of how to implement a simple console logger.

class BackgroundDeliveriesLogger implements SpikeBackgroundDeliveriesLogger {
  onBackgroundLog(log: string) {
    console.log(`[BACKGROUND_LOG] ${log}`);
  }
}
