First, remember that PendingIntents may not be unique w.r.t extra bundles, which is why you want to use the setData() Uri.
In the Activity or Service that you trigger with the PendingIntent, you can use getIntent().getData() to read back the Uri used to launch it, which includes any data you set when building the widget update. Here's an example where I used the setData() approach to sharing the appWidgetId. When opening the forecast details page, you need to know the source widget the user clicked on: http://code.google.com/p/android-sky/source/browse/trunk/Sky/src/org/jsharkey/sky/MedAppWidget.java#166 http://code.google.com/p/android-sky/source/browse/trunk/Sky/src/org/jsharkey/sky/DetailsActivity.java#98 j On Thu, May 7, 2009 at 2:58 AM, Carlos <[email protected]> wrote: > > Ok. > But how to find the id to join it in the intent? > > > When i update my widget, i do : > updateViews.setOnClickPendingIntent(R.id.widget, pendingIntent); > the pendingintent has an extra value with the widget id.
