AppWidget ID Life

I have an application with some AppWidget s. I store some information about each widget, including its appWidgetId inside the database. I need this information to properly update each widget. The problem is that after rebooting the device I can no longer address these appWidgetId , as it seems that they are changing their values. How can I solve this problem? Thanks in advance.

It seems that only on some devices the appwidget ids change on reboot (due to an error). See this thread .

I looked at the Android source. Appwidget identifiers are indeed stored in a file in /data/system/appwidgets.xml . Your device may have the error indicated in this thread.

I can’t think of a suitable job.

I think Dheeraj is right. I am also a developer of Android Widgets and do the same as you: I save the settings for each widget, remembering WidgetId. This works flawlessly on all the devices that I know. The identifier does not change after reboot on all devices that I know. Are you confident in your observations?

The new appWidgetId propagates in R.java every time you launch the application instead of storing the id from R.java, you can store the id from android: id = "@ + id / btn_add" in your database.
