In part 2 of the app widget tutorial, we add a configuration activity to our app, which starts when our widget is dragged onto the homescreen and where we can do an initial setup. We get our appWidgetId from the intent with the AppWidgetManager.EXTRA_APPWIDGET_ID key and can then make changes to this widget with help of the RemoteViews class. We will give the user the option to set his own button text and as in the last video we set a PendingIntent to our button which will open our MainActivity when clicked. We will also save the button text to SharedPreferences and then finish our activity with RESULT_OK and pass the appWidgetId back. In case we don’t get passed a valid id, our appWidgetId will be set to AppWidgetManager.INVALID_APPWIDGET_ID.
In our AppWidgetProvider class we retrieve the button text from shared preferences in our onUpdate method and reset it together with the pending intent to our button.
In our AndroidManifest.xml file we have to set the android.appwidget.action.APPWIDGET_CONFIGURE intent filter for our config activity and in the info xml file we have to add the android:configure attribute.
