OSMdroid - error: no suitable constructor found for Overlay(no arguments) constructor Overlay.Overlay(Context) is not applicable

Question

While extending OSMdroid Overlay class in an application

import org.osmdroid.views.overlay.Overlay;
...
public class MapOverlayArea extends Overlay implements TextToSpeech.OnInitListener, OnTouchListener  {

...

I receive an error:

error: no suitable constructor found for Overlay(no arguments) constructor Overlay.Overlay(Context) is not applicable

Answer 1

As indicated by the error message, the required constructor was missing.

public class MapOverlayArea extends Overlay implements TextToSpeech.OnInitListener, OnTouchListener  {

    public MapOverlayArea(Context ctx) {
        super(ctx);
    }

    //....
}

Including the constructor as above, and calling it correctly from main activity using

MapOverlayArea mapOverlayArea = new MapOverlayArea(context);

solves the problem.
