Well Landy I don't know about the stack trace file error but what I do know is that the methods you are trying to use for zoom controls are deprecated. The new method is getting your MapView like you have and then instead of having your linear layout you simply put:
MapView map = (MapView) findViewById(R.id.mapview); map.setBuiltInZoomControls(true); This method does all the work for you and even hides itself if the user isn't using it! I had this problem too. The tutorial is out of date and there are actually two different ones on the developer website. Hopefully this helps!
