Answer 1

Create an inner class in the non Activity class and define your activity results handler therein:

class singletonActivity extends Activity{
  protected void onActivityResult(...){
    // do whatever ..
  }
}

intantiate it to call startActivityForResult

Activity actv = new singletonActivity(..)
actv.startActivityForResult(intent ..)

your handler will be called. :)

ps: you may have to include some overrides. just leave them empty.

pps: this is old school java mouseListenerAdapter style ~Oo>
