Android MapFragment Runtime Error - Could not find class 'maps.jk'

I am using SupportMapFragment with complete success. I do not have any problems.

However, while the application is running, I get an error message. I work for Gingerbread Phone and it has the very latest GooglePlay. Also note that I am using SupportMapFragment and other support classes to serve pre-Honeycomb.

Could not find class 'maps.j.k', referenced from method maps.y.ae.a`

An error occurs as soon as I inflate my idea.

inflater.inflate(R.layout.fragment_map, container, false);

My layout file (fragment_map.xml):

<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1" />

My fragment class (contains SupportMapFragment)

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    super.onCreateView(inflater, container, savedInstanceState);

    View v = inflater.inflate(R.layout.fragment_maps, container, false);
    return v;
}

I have all the necessary permissions in my manifest, as described here .

This does not cause any problems, but I wonder what that means. I did not find the answers
