If everything is given right then check whether nullpointer exception occur in myMapview object. since you have declared at top then inside onCreate you are using MapView mymapView=(MapView) findViewById(R.id.mapview); so when you use mymapview object inside setStallite() it will take only the object which was declare at the top. so try this

  myMapView = (MapView) findViewById(R.id.mapview);

but you to declare myMapview at top as MapView myMapview;

check this if not please post your error in logcat
