 </RelativeLayout> 

Answer 1

If you use

class="com.google.android.gms.maps.SupportMapFragment"

Then you have to use the SupportMapFragment class in your activities. Example:

SupportMapFragment mapa;
mapa = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

Hope it helps
