A React Native bridge module for interacting with Google Fit

Package Exports

  • google-fit

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (google-fit) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

USAGE

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

  2. Authorize:

    // 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')
 })

  3. Retrieve Steps For Period

    const options = {
  startDate: "2017-01-01T00:00:17.971Z", // required ISO8601Timestamp
  endDate: new Date().toISOString() // required ISO8601Timestamp
};

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

    Response:

    [
  { source: "com.google.android.gms:estimated_steps", steps: [
    {
      "date":"2019-06-29","value":2328
    },
    {
      "date":"2019-06-30","value":8010
      }
    ]
  },
  { source: "com.google.android.gms:merge_step_deltas", steps: [
    {
      "date":"2019-06-29","value":2328
    },
    {
      "date":"2019-06-30","value":8010
      }
    ]
  },
  { source: "com.xiaomi.hm.health", steps: [] }
];

  4. Retrieve Weights

    const 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);
});

    Response:

    [
  {
    "value":72,
    "endDate":"2019-06-29T15:02:23.413Z",
    "startDate":"2019-06-29T15:02:23.413Z",

    "startDate":"2019-07-26T08:06:42.903Z",
    "day":"Fri"
  }
]

  5. Retrieve Heights

    const opt = {
  startDate: "2017-01-01T00:00:17.971Z", // required
  endDate: new Date().toISOString(), // required
};

GoogleFit.getHeightSamples(opt, (err, res) => {
  console.log(res);
});

    Response:

    [
  {
    "value":1.7699999809265137,
    "endDate":"2019-06-29T15:02:23.409Z",
    "startDate":"2019-06-29T15:02:23.409Z",
    "day":"Sat"
  }
]

  6. Save Weights

    const opt = {
  value: 200,
  date: new Date().toISOString(),
  unit: "pound"
};

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

  7. Blood pressure and Heart rate methods (since version 0.8)

    const options = {
  startDate: "2017-01-01T00:00:17.971Z", // required
  endDate: new Date().toISOString(), // required
}
const callback = ((error, response) => {
  console.log(error, response)
});

GoogleFit.getHeartRateSamples(options, callback)
GoogleFit.getBloodPressureSamples(options, callback)

    Response:

    // heart rate
[
  {
    "value":80,
    "endDate":"2019-07-26T10:19:21.348Z",
    "startDate":"2019-07-26T10:19:21.348Z",

// blood pressure
[
  {
    "value":120,
    "value2":80,
    "endDate":"2019-07-26T08:39:28.493Z",
    "startDate":"1970-01-01T00:00:00.000Z",
    "day":"Thu"
  }
]

  8. Get all activities

      let options = {
    startDate: new Date(2018, 9, 17).valueOf(), // simply outputs the number of milliseconds since the Unix Epoch
    endDate: new Date(2018, 9, 18).valueOf()
  };
  GoogleFit.getActivitySamples(options, (err, res) => {
    console.log(err, res)
  });

    Response:

     [ { 
  sourceName: 'Android',
  device: 'Android',
  sourceId: 'com.google.android.gms',
  calories: 764.189208984375,
  quantity: 6,
  end: 1539774300992,
  tracked: true,
  activityName: 'still',
  start: 1539727200000 },
{ sourceName: 'Android',
  device: 'Android',
  sourceId: 'com.google.android.gms',
  calories: 10.351096153259277,
  quantity: 138,
  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.

  9. Retrieve Calories For Period

      const opt = {
    startDate: "2017-01-01T00:00:17.971Z", // required
    endDate: new Date().toISOString(), // required
    basalCalculation: true, // optional, to calculate or not basalAVG over the week
  };

  GoogleFit.getDailyCalorieSamples(opt, (err, res) => {
    console.log(res);
  });

    Response:

    [
  {
    "calorie":1721.948974609375,
    "endDate":"2019-06-27T15:13:27.000Z",
    "startDate":"2019-06-27T15:02:23.409Z",
    "day":"Thu"
  },
  {
    "calorie":1598.25,
    "endDate":"2019-06-28T15:13:27.000Z",
    "startDate":"2019-06-27T15:13:27.000Z",
    "day":"Thu"
  }
]

  10. Retrieve Distance For Period:

      const opt = {
    startDate: "2017-01-01T00:00:17.971Z", // required
    endDate: new Date().toISOString(), // required
  };

  GoogleFit.getDailyDistanceSamples(opt, (err, res) => {
    console.log(res);
  });

    Response:

    [
  {
    "distance":2254.958251953125,

    "day":"Sun"
  }
]

    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 save weights)

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