Error getting location on Activity in Android

Question

I have to put the actual value of my location in a variable but I have this error:

java.lang.IllegalStateException: Could not execute method of the activity

My code is:

@Override
public void onLocationChanged(Location location) {
    mCurrentLocation = location;
    Latit = mCurrentLocation.getLatitude();

    Location objLoc = new Location("");
    objLoc.setLatitude(location.getLatitude());
    objLoc.setLongitude(location.getLongitude());
}

@Override
public void onConnected(Bundle bundle) {
    startLocationUpdates();
}

public void locInicio(View v) {
    TextView inicioLat = (TextView) findViewById(R.id.eInicioLat);
    Latit = mCurrentLocation.getLatitude();
    inicioLat.setText((int) Latit);

}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.adicionar);
    buildGoogleApiClient();
}

In other activity I can get the value with onLocationChanged but it always returns an error.

You simply need to take care of cases where location is null in onLocationChanged. e.g. if (location == null) return; as the fist line in the method. — cYrixmorten

You simply need to take care of cases where location is null in onLocationChanged. e.g. if (location == null) return; as the fist line in the method.

@Override
public void onLocationChanged(Location location) {
    if (location == null) return;

    mCurrentLocation = location;
    Latit = mCurrentLocation.getLatitude();

    // by the way - why do you do this??
    Location objLoc = new Location("");
    objLoc.setLatitude(location.getLatitude());
    objLoc.setLongitude(location.getLongitude());
}

public void locInicio(View v) {
    TextView inicioLat = (TextView) findViewById(R.id.eInicioLat);

    // here is your problem
    if (mCurrentLocation == null) return; 

    Latit = mCurrentLocation.getLatitude();
    inicioLat.setText((int) Latit);

}
