these are my codes to open GPS
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.setTestProviderEnabled("gps", true);
and the permission in my xml
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"/>
but the apps crashed.
