I am working on step count implementation and for that i am using the google fit api of android.
Below is my code.
public class GoogleFitDemoActivity extends AppCompatActivity {
public static final String TAG = "BasicSensorsApi";
private GoogleApiClient mClient = null;

super.onCreate(savedInstanceState);
setContentView(R.layout.google_fit_main);
progressDialog = new ProgressDialog(this);
if (!checkPermissions()) {
requestPermissions();
Debug.displayToast(this, "Requesting for permisstion ");
}
stepsCountTextView = (TextView) findViewById(R.id.sample_logview);
}

}

return;

mListener)

} else {

}
}
});
}

Below are issue in this code which i am facing.
(Let suppose I have started walking and steps count is 10 and I kill my all and again start app once my onConnected() is called I register for getting data point and I get the dataPoint value 10 while it should give 0 to start from first
1 The step value does not reset to 0 and continues to increment.
2 Every-time I run the code the steps value doesn't reset to 0, so it is taking in some past values.
3 Not getting the steps count update as frequently it is taking time to update.(when i walk for 5 min then it gives first step count)
4 Even after killing app and again relaunching app get the previous steps count,steps count not start form 0 start from old.(As I am not storing any values in preference or database. How I am getting the previous step count like 10)
Please see the result log
Detected DataPoint value: 1 >>>>>>>>>> at this it should be start from 0
Detected DataPoint field: steps Detected DataPoint value: 1
Detected DataPoint field: steps Detected DataPoint value: 6
Detected DataPoint field: steps Detected DataPoint value: 6
Detected DataPoint field: steps Detected DataPoint value: 7
Detected DataPoint field: steps Detected DataPoint value: 7
Detected DataPoint field: steps Detected DataPoint value: 2
Please help where i am making the mistake.
