Unable to create Google map fragment

Question

Trying to implement google map API in my android project and getting the warning error that is under my java code

GoogleMap gMap;

gMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

LatLng Jamaica = new LatLng(18.1155173, -77.2760026);

gMap.moveCamera(CameraUpdateFactory.newLatLngZoom(Jamaica, 13));

gMap.addMarker(new MarkerOptions()
    .title("Jamaica")
    .snippet("The greatest country in the world")
    .position(Jamaica));
gMap.setMyLocationEnabled(true);

Logcat:

03-18 12:45:00.140: W/ActivityThread(10477): ClassLoader.loadClass: The class loader returned by Thread.getContextClassLoader() may fail for processes that host multiple applications. You should explicitly specify a context class loader. For example: Thread.setContextClassLoader(getClass().getClassLoader());

Answer 1

1. Run `cmd` and genereate a new "SHA1" key.
2. Browse to https://code.google.com/apis/console/?noredirect `API Console` page.
3. Replace the old "ShA1" with the new "sha1" key.
4. Then replace your new map key.

Your problem solved. I also had this problem. (I only changed my map key)

Answer 2

Did you add

<uses-library android:name="com.google.android.maps" />

to your manifest under the application tag?
