Android :: GPS Application Not Installing In Sony Xperia

I created an application in 1.6 SDK. It uses GPS. But its not installing in Sony Xperia. I installed other application developed in 1.6 SDK and its working fine. But when I am using GPS its not working. The code is like this,

public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000L, 500.0f,this);}
