Disappearing AppWidgets for Android Development

I am developing an appwidget for android. It works fine whe开发者_如何学Gon installing and running, but whenever the device is rebooted, the program can no longer use that widget. The activity is still selectable in the launcher, but there is no way to add the widget to the home screen without reinstalling the program.

Have you hear of this happening? How can I fix this problem? Thanks so much!

Apps installed to SD cannot have widgets. If you installed an app to SD, you first need to move it back to internal storage and then reset the phone before you can see the widget.

See the documentation for a list of things that require installation to internal storage, and how to set up the manifest properly.
