I'm new to android so my suggestion may look guffy but what if you'll just create a reference to your activity as a private property and assign that in OnCreate method? You can even create your CustomActivity with OnCreate like that and derive all your activities from your CustomActivity, not generic Activity provided by adnroid.

class blah extends Activity{
  private Activity activityReference;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        activityReference = this;
    }

}

after that you could use that the way you want, i.e. in

Intent i = new Intent(activityReference, SomeOtherActivity.class)

etc
