Your error trace shows ClassCastException

java.lang.ClassCastException: com.google.android.gms.maps.MapFragment cannot be cast to android.support.v4.app.Fragment

It means You are using API less than 11 with FragmentActivity and MapFragment. Try to update API > 11 with Activity and MapFragment.

If you want to continue with API < 11 then use SupportMapFragment instead of MapFragment.

Refer this to implement MapFragment with API > 11 Google Map v2

In your layout it looks like your using a MapFragment. Use android:name="com.google.android.gms.maps.SupportMapFragment" instead and in your onCreate, get the MapFragment like so:

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapFragment); //your SupportMapFragment's id will need to be set to this in your layout.

See my blog posts i have tried to summarize all there is needed to build an App with Google Maps API V2 for Android.

  1. Solution to Problems with Maps API V2(using google_play_services_lib).
  2. Creating an Android App with Maps API V2 for minSDK=8 (Android 2.2 Froyo).
  3. Creating an Android App with Maps API V2 for minSDK=11 (Android 3.0 HoneyComb).

If you want to implement Google maps in your application and you want your application to target API < 11 then you will have to use the FragmentActivity. FragmentActivity is part of google-support-v4 library and basically gives you support for fragment for system prior to API level 11. in this case you would have to import this library. you can get an idea of how it's done by reading step 4 of this blog post I wrote on Google Maps integration:

Google Maps API V2

You just have to remember that if this is the way you go you should use the SupportMapFragment object for you map instead of the MapFragment you are using currently.

If on the other hand you develop you app to API's level 11 and higher this step is not necessary and you simply can use a simple Activity with a MapFragment.
