Question

I am using a MapView with a default location. If I go to another location on the map and then change the orientation of the device, the orientation does not save my previous location. It starts from the default location!

How can I avoid this? I do not want to disable the screen-oreintation change for my application.

Answer 1

Use the method onRetainNonConfigurationInstance() to save the location and then use getLastNonConfigurationInstance() in onCreate() to restore the selected item.

@Override
public Object onRetainNonConfigurationInstance() {
    return mapView.getMapCenter();
}

@Override
protected void onCreate(Bundle icicle) {
    Geopoint center = (Geopoint) getLastNonConfigurationInstance();

    if (point != null)
        mapView.getController().animateTo(center);
}
