My app uses GoogleApiClient to get the current location. It works well for the first time but if I close my app and then open it again, it crashes (on Sony Xperia Z3, Google Pixel).

On Asus, Samsung, ... it doesn't crash

android.os.DeadObjectException

I found the line of code that causes a crash is GoogleApiClient.connect(), I also use try-catch, update to the latest Google API 11.8.0 but can not find a possible solution. Here is my code

@Override
public void onLocationChanged(Location location) {
    if (location != null) {
        Log.v(">>>", "onLocationChanged Longitude = " + Constants.location.getLongitude() + ", Latitude = " + Constants.location.getLatitude());
        //Toast.makeText(this, "onLocationChanged Longitude = " + Constants.location.getLongitude() + ", Latitude = " + Constants.location.getLatitude(), Toast.LENGTH_SHORT).show();
        saveLocation(location);
    }
}

@Override
public void onConnected(@Nullable Bundle bundle) {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
            && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        try {
            Location mLastLocation = LocationServices.FusedLocationApi
                    .getLastLocation(mGoogleApiClient);
            if (mLastLocation != null) {...}

                //Toast.makeText(this, "onConnected Longitude = " + Constants.location.getLongitude() + ", Latitude = " + Constants.location.getLatitude(), Toast.LENGTH_SHORT).show();
            }
            startLocationUpdates();
        } catch (Exception ex) {
            // This will catch the exception, handle as needed
        }
    }
    //Toast.makeText(this, "onConnected", Toast.LENGTH_SHORT).show();
}

@Override
public void onConnectionSuspended(int i) {
    mGoogleApiClient.connect();
}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    Log.d("Location service", "onConnectionFailed");
}

@Override
protected void onResume() {
    super.onResume();
    checkPlayServices();
    // Resuming the periodic location updates
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        startLocationUpdates();
    }
    Log.v(">>>", "onResume");
}

@Override
protected void onStart() {
    super.onStart();
    if (mGoogleApiClient != null) {
        mGoogleApiClient.connect(); // CRASH HERE
        Log.v(">>>", "GoogleApiClient.connect()");
    }
    Log.v(">>>", "onStart");
}

@Override
protected void onStop() {
    if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
        mGoogleApiClient = null;
        Log.v(">>>", "GoogleApiClient.disconnect()");
    }
    super.onStop();
    Log.v(">>>", "onStop");
}

@Override
protected void onPause() {
    stopLocationUpdates();
    super.onPause();
    Log.v(">>>", "onPause");
}

DeadObjectException - The object you are calling has died, because its hosting process no longer exists.That is service had already stopped - either killed from the OS, or stopped from your application.

Override your onDestroy() method and watch what event leads to DeadObjectException. If you catch DeadObjectException without going through this method, your service should have been killed by the OS.

In onLocationChanged(location), saveLocation(location) uses RealmIO to save user's last location.

If I remove saveLocation(location), everything works well.

I found that if I use (RealmIO) or (SharedPreferences with Gson) to save data, the problem occurs

The temporary solution is using SharedPreferences without Gson:

SharedPreferences prefs = context.getSharedPreferences(
           LAST_LOCATION, Context.MODE_PRIVATE);
    prefs.edit().putString(LAST_LOCATION_LONGITUDE, location.getLongitude() + "").apply();
    prefs.edit().putString(LAST_LOCATION_LATITUDE, location.getLatitude() + "").apply();

I don't know why the crash just happens in some specific devices. Hope this help someone!
