There are 3 buttons on the screen! Start, View Map, Stop
When I click View Map, it should go to a new screen that shows the map! But something goes wrong and the app is getting force closed! I believe the problem is with the xml files. Please someone correct it.

In addition to the Map button block, this also has blocks for start and stop, but they work correctly.

You need to create a separate layout .xml file for your map view. Create a new xml called map.xml in res->layout and past this in.
Note: your MapViewer class should extend a MapActivity, not a MainActivity.
Make sure you set the content view to the new file in your map activity.
