title: Android appWidget multiple instances
body: <p>This question is pretty much a duplicate of <a href="https://stackoverflow.com/questions/4225197/android-multiple-appwidgets-playing-diferent-sounds">Android - Multiple appWidgets playing different sounds</a>, but my code isn't working. I am adding an intent extra with the widget id, with log statements to prove it, but whenever I click on one of my widgets when there are multiple instances of it, I only get the last appWidgetId. It looks like the intent of the first widget is changing after the second one is added. If the code in that other post should work, then I must be overlooking something because I believe mine is set up pretty much the same way.</p>

  <p>I've been working on this for two days and I do hope that someone can point out the err of my ways. A virtual e-beer awaits the person who can solve this :)</p>
