Answer 1

You class must extend FragmentActivity. Make sure you have added support library.

SupportMapFragment fm = (SupportMapFragment)   getSupportFragmentManager().findFragmentById(R.id.map);
mMap = fm.getMap(); 

Also in your xml

<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Also make sure you have imported

 import android.support.v4.app.FragmentActivity;  
 import com.google.android.gms.maps.SupportMapFragment;  

Answer 2
