ActivityForResult from Widget
<p>I have a button in my main activity (act1) and in a widget. That button starts a different activity (act2).</p>

<p>In act1, I start act2 by doing startActivityForResult. When it's done, I handle it with onActivityResult.</p>

<p>However, in the widget, I start act2 by using a PendingIntent. When act2 is finished, it returns to act1 but does not trigger onActivityResult.</p>

<p>How do I make it hit onActivityResult when it returns to act1 or at least find out if act2 was started by the widget?</p>
