Question

Running slightly modified example of Google Maps throws BadParcelableException in the Google Maps code. The LatLng class is parcelable but it canno

Answer 1

I tried the two previous answers without success, but I found another workaround :

When saving the state, be careful to forward the MapView.onSaveInstanceState call before adding your data to the Bundle (you did it well) :

@Override
public void onSaveInstanceState(Bundle outState) {

    // Forward the call BEFORE adding our LatLng array, else it will crash :
    _mapView.onSaveInstanceState(outState);

    // Put your Parcelable in the bundle:
    outState.putParcelableArray("myLatLng", new LatLng(0, 0) );
}

When restoring the state in the onCreate / onRestore, check if the bundle is not null, if so, get your parcel, and then remove it from the bundle before forwarding the call :

@Override
public void onCreate(Bundle savedInstanceState) {

    // If the bundle is not null, get your Parcelable :
    LatLng myLatLng = null;
    if(savedInstanceState != null) {

        myLatLng = (LatLng) savedInstanceState.getParcelable("myLatLng");

        // Remove your Parcelable from the bundle, else it will crash :
        savedInstanceState.remove("myLatLng");
    }

    // Forward the call :
    _mapView.onCreate(savedInstanceState);
    setUpMapIfNeeded();
}
