Step to reproduce:
- configure the DevDrawer with your package (com.example.*)
- add the widget your home
- install an application with the com.example. ... package from Eclipse or with ADB anyway
- look at the widget: it stay empty
For me the widget is updated only after a long time the app has been installed (dunno if that happen when Android decide to kill the widget and thus it is re-created or not).
Tested on a Samsung Nexus S.
