I am working on an application where I want to read user's step count as well as other fitness related information like heart rate (when connected to a smart band) from both mobile sensors as well as any other fitness devices supported by Google Fit SDK.

I am trying to use Google's Fit SDK for android and trying to access the data through Sensor API but every time the code is executed I get an error: "SIGN IN REQUIRED". I don't want the user to sign in to a particular google account. I have my own login system. I also don't want to store the data in fitness store as I have my own back-end. All I want is to access the data from sensors.

Here is the dummy code which I tried:

private GoogleApiClient googleApiClient;



private static final int REQUEST_OAUTH = 1001;



private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener

        = new BottomNavigationView.OnNavigationItemSelectedListener() {



    @Override

    public boolean onNavigationItemSelected(@NonNull MenuItem item) {

        switch (item.getItemId()) {

            case R.id.navigation_home:

                mTextMessage.setText(R.string.title_home);

                return true;

            case R.id.navigation_dashboard:

                mTextMessage.setText(R.string.title_dashboard);

                return true;

            case R.id.navigation_notifications:

                mTextMessage.setText(R.string.title_notifications);

                return true;

        }

        return false;

    }

};



@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_home);



    mTextMessage = (TextView) findViewById(R.id.message);

    BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);

    navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);



    googleApiClient = new GoogleApiClient.Builder(this)

            .addApi(Fitness.SENSORS_API)

            .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))

            .addConnectionCallbacks(this)

            .addOnConnectionFailedListener(this)

            .build();

    googleApiClient.connect();



    PendingResult<Status> pendingResult = Fitness.SensorsApi.add(

            googleApiClient,

            new SensorRequest.Builder()

                    .setDataType(DataType.TYPE_STEP_COUNT_DELTA)

                    .setSamplingRate(1, TimeUnit.MINUTES)  // sample once per minute

                    .build(),

            new OnDataPointListener() {

                @Override

                public void onDataPoint(DataPoint dataPoint) {

                    Log.e("Data Point", dataPoint.toString());

                }

            });

}



@Override

public void onConnected(@Nullable Bundle bundle) {



}



@Override

public void onConnectionSuspended(int i) {



}



@Override

protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {

    if (requestCode == REQUEST_OAUTH && resultCode == RESULT_OK) {

        googleApiClient.connect();

    }

}



@Override

public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    if (connectionResult.getErrorCode() == FitnessStatusCodes.NEEDS_OAUTH_PERMISSIONS) {

        try {

            connectionResult.startResolutionForResult(this, REQUEST_OAUTH);

        } catch (IntentSender.SendIntentException e) {

        }

    }

}

Is it possible to achieve this through fitness sdk without login and if not what is the other alternative to access this information in Android.

I read somewhere that I can use sensor manager but I guess with it I have to make all the calculations myself like removing bad data points received from sensor due to sudden jerk etc which I think fitness-sdk is already doing.
