Now that you have the Maps API set up, you need to create a map. Maps are displayed, appropriately enough, in a MapView. MapView is like other views, mostly, except in one way: For it to work correctly, you have to forward all of your lifecycle events, like this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    mMapView.onCreate(savedInstanceState);
}

This is a huge pain in the neck. It is far easier to let the SDK do that work for you instead by using a MapFragment or, if you are using support library fragments, SupportMapFragment. The MapFragment will create and host a MapView for you, including the proper lifecycle callback hookups.

Your first step is to wipe out your old UI entirely and replace it with a SupportMapFragment. This is not as painful as it might sound. All you need to do is switch to using a SupportMapFragment, delete your onCreateView(…) method, and delete everything that uses your ImageView.

public class LocatrFragment extends SupportMapFragment Fragment{
    private static final String TAG = "LocatrFragment";
    private static final String[] LOCATION_PERMISSIONS = new String[]{
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION,
    };
    private static final int REQUEST_LOCATION_PERMISSIONS = 0;

    private ImageView mImageView;
    private GoogleApiClient mClient;
    ...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_locatr, container, false);

        mImageView = (ImageView) v.findViewById(R.id.image);

        return v;
    }
    ...
    private class SearchTask extends AsyncTask<Location,Void,Void> {
        ...
        @Override
        protected void onPostExecute(Void result) {
            mImageView.setImageBitmap(mBitmap);
        }
    }
}

SupportMapFragment has its own override of onCreateView(…), so you should be all set. Run Locatr to see a map displayed (Figure 34.1).
