Issue after updating android-maps-extensions to a newer version

Question

I had been using an older version of the said library in a project of mine. However, today when I updated to the latest version, I realized that its package names etc had changed (major version switch from 1.x.x to 2.x.x).

From pl.mg6.android.maps.extensions.SupportMapFragment it was now com.androidmapsextensions.SupportMapFragment.

I made the necessary import changes. However, the following line in my code that worked fine before is now showing an error:

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

map is of type GoogleMap (com.androidmapsextensions.GoogleMap).

Here is the map in my XML

<fragment
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    class="com.androidmapsextensions.SupportMapFragment" />

As you can see I've changed the XML from pl6.... to the new package name too.

What am I doing wrong?
