Android getResource() undefined error

I want to draw bitmap on draw method in MyPositionOverlay extends Overlay class but I get this error: The method getResource() is undefined for the type MyPositionOverlay

Where I'm wrong?

Here is code form draw method:

  Bitmap bmp = BitmapFactory.decodeResource(getResource(), R.drawable.icon); 
     canvas.drawBitmap(bmp, screenPts.x, screenPts.y-50, null);

Thanks

use

   Bitmap bmp = BitmapFactory.decodeResource(this.getResources(), R.drawable.icon);

or 

Bitmap bmp = BitmapFactory.decodeResource(Context.getResources(), R.drawable.icon);

The getResources() method is not a member of the Overlay class. getResources() is a member of the Context class. You need to pass a reference of a Context to your Overlay subclass so that it can load the Drawable resource:

Bitmap bmp = BitmapFactory.decodeResource(context.getResources(), R.drawable.icon);

You also don't want to load a bitmap in your draw method as it is very memory intensive and will slow down your application, you should save a member variable of the bitmap in the constructor of the overlay so that it only gets loaded once.
