USAGE

import GoogleFit, { Scopes } from 'react-native-google-fit'

Authorize:

To check whethere GoogleFit is already authorized, simply use a function

    GoogleFit.checkIsAuthorized()

Then you can simply refer to GoogleFit.isAuthorized boolean.

// The list of available scopes inside of src/scopes.js file
const options = {
  scopes: [
    Scopes.FITNESS_ACTIVITY_READ_WRITE,
    Scopes.FITNESS_BODY_READ_WRITE,
  ],
}
GoogleFit.authorize(options)
  .then(authResult => {
    if (authResult.success) {
      dispatch("AUTH_SUCCESS");
    } else {
      dispatch("AUTH_DENIED", authResult.message);
    }
  })
  .catch(() => {
    dispatch("AUTH_ERROR");
  })

// ...
// Call when authorized
GoogleFit.startRecording((callback) => {
  // Process data from Google Fit Recording API (no google fit app needed)
});

Alternatively you can use event listeners (deprecated)

 GoogleFit.onAuthorize(() => {
   dispatch('AUTH SUCCESS')
 })
     
 GoogleFit.onAuthorizeFailure(() => {
   dispatch('AUTH ERROR')
 })

Retrieve Steps For Period

const options = {
  startDate: "2017-01-01T00:00:17.971Z", // required ISO8601Timestamp
  endDate: new Date().toISOString(), // required ISO8601Timestamp
  bucketUnit: "DAY", // optional - default "DAY". Valid values: "NANOSECOND" | "MICROSECOND" | "MILLISECOND" | "SECOND" | "MINUTE" | "HOUR" | "DAY"
  bucketInterval: 1, // optional - default 1. 
};

GoogleFit.getDailyStepCountSamples(options)
 .then((res) => {
     console.log('Daily steps >>> ', res)
 })
 .catch((err) => {console.warn(err)})

// shortcut functions, 
// return weekly or daily steps of given date
// all params are optional, using new Date() without given date, 
// adjustment is 0 by default, determine the first day of week, 0 == Sunday, 1==Monday, etc.
GoogleFit.getDailySteps(date).then.catch()
GoogleFit.getWeeklySteps(date, adjustment).then().catch()

Response:

 [ { 
  sourceName: 'Android',
  device: 'Android',
  sourceId: 'com.google.android.gms',
  calories: 764.189208984375,
  quantity: 6,
  end: 1539774300992,
  tracked: true,
  activityName: 'still',
  start: 1539727200000 },

  device: 'Android',
  sourceId: 'com.google.android.gms',
  calories: 10.351096153259277,

  end: 1539774486088,
  tracked: true,
  distance: 88.09545135498047,
  activityName: 'walking',
}]

Where:

sourceName = device - 'Android' or 'Android Wear' string
sourceId - return a value of dataSource.getAppPackageName(). For more info see: https://developers.google.com/fit/android/data-attribution
start/end - timestamps of activity in format of milliseconds since the Unix Epoch
tracked - bool flag, is this activity was entered by user or tracked by device. Detected by checking milliseconds of start/end timestamps. Since when user log activity in googleFit they can't set milliseconds
distance(opt) - A distance in meters.
activityName - string, equivalent one of these https://developers.google.com/fit/rest/v1/reference/activity-types 
calories(opt) - double value of burned Calories in kcal.
quantity(opt) - equivalent of steps number

Note that optional parametrs are not presented in all activities - only where google fit return some results for this field. Like no distance for still activity.

Retrieve Hydration

You need to add FITNESS_NUTRITION_READ_WRITE scope to your authorization to work with hydration.

const startDate = '2020-01-05T00:00:17.971Z'; // required

Save Hydration

This method can update hydration data. An app cannot update data inserted by other apps.

const hydrationArray = [
  {
    date: Date.parse('2020-02-01'), // required, timestamp
    waterConsumed: 0.225, // required, hydration data for a 0.225 liter drink of water
  },
  {
    date: Date.parse('2020-02-02'),
    waterConsumed: 0.325,
  },
];

GoogleFit.saveHydration(hydrationArray, (err, res) => {
  if (err) throw "Cant save data to the Google Fit";
});

Delete Hydration

An app cannot delete data inserted by other apps. startDate and endDate MUST not be the same.

const options = {
  startDate: '2020-01-01T12:33:18.873Z', // required, timestamp or ISO8601 string
  endDate: new Date().toISOString(), // required, timestamp or ISO8601 string
};

GoogleFit.deleteHydration(options, (err, res) => {
  console.log(res);
});

Retrieve Sleep

    GoogleFit.getSleepData(options, (err, res) => {
  console.log(res)
});

Other methods:

observeSteps(callback); // On Step Changed Event

unsubscribeListeners(); // Put into componentWillUnmount() method to prevent leaks

isAvailable(callback); // Checks is GoogleFit available for current account / installed on device

isEnabled(callback); // Checks is permissions granted

deleteWeight(options, callback); // method to delete weights by options (same as in delete hydration)

openFit(); //method to open google fit app

saveHeight(options, callback);

deleteHeight(options, callback); // method to delete heights by options (same as in delete hydration)

disconnect(); // Closes the connection to Google Play services.
