POAndroid appWidget multiple instances

copied!<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> <pre><code> public class PhcaAppWidgetProvider extends AppWidgetProvider { private static final String ACTION_CLICK = "com.skipmorrow.phca.PhcaAppWidgetProvider.WIDGET_CLICKED"; private final String widgetPageName = "_widget"; private static final String PREFS_NAME = "PHCA"; private static final String PREF_PREFIX_KEY = "prefix_"; private static String MY_DEBUG = "PhcaAppWidget"; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Log.d(MY_DEBUG, "Provider.onUpdate"); } @Override public void onReceive(Context context, Intent intent) { String intentAction = intent.getAction(); Log.d(MY_DEBUG, "Provider.onReceive(); action = " + intentAction); Bundle extras = intent.getExtras(); // make a list of all extras, just so I can see what is in there... if (extras!=null) { Set<String> ks = extras.keySet(); Iterator<String> iterator = ks.iterator(); while (iterator.hasNext()) { String s = iterator.next(); Log.d(MY_DEBUG, "Provider.Key found: " + s); } } else { Log.d(MY_DEBUG, "Provider.extras was null"); } int[] appWidgetIds1 = intent.getIntArrayExtra("appWidgetIds"); if (extras!=null && extras.containsKey("appWidgetIds")){ // sometimes the intent comes back with an array of appWidgetIds, and sometimes the appWidgetId is stored // in the one extra "appWidgetId" Clicks never come with the array of appWidgetIds.

A virtual e-beer awaits the person who can solve this :)</p>
