USAGE

1. import GoogleFit from 'react-native-google-fit';

2. Authorize:

   GoogleFit.authorize()
    .then(() => {
      dispatch('AUTH_SUCCESS')
    })
    .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

    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: [] },
  { source: "com.google.android.gms:merge_step_deltas", steps: [] },
  { 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);
   });

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);
   });

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, resoponse) => {
      
      })
      GoogleFit.getHeartRateSamples(options, callback)
      GoogleFit.getBloodPressureSamples(options, callback)

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. Other methods:

   observeSteps(callback); // On Step Changed Event
   
   unsubscribeListeners(); // Put into componentWillUnmount() method to prevent leaks
   
   getDailyCalorieSamples(options, callback); // method to get calories per day
   
   getDailyDistanceSamples(options, callback); // method to get daily distance
   
   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
   
   saveHeight(options, callback);
   
   deleteHeight(options, callback);
   
   deleteWeight(options, callback);
   
   disconnect(); // Closes the connection to Google Play services.
