public class main extends Activity

you should use either AppCompatActivity or FragmentActivity, E.g.

public class mai extends AppCompatActivity

instead of

public class main extends Activity

ERROR: Cannot cast from Fragment to MapFragment – Rishabh Srivastava Sep 27 '13 at 10:13
What happens is that when you extend Fragment Activity instead of Activity, it means that you will not be able to call your activity from another activity that does not extend Fragment activity and this becomes a challenge. I have tried to do this but what I have been getting is NoClassDefFoundError. In this instance how does one call the activity in another class – olasammy Oct 10 '13 at 16:05
