I add a configure/settings Activity in my AppWidget and started gotting some problems. At first, I didn't knew what is the cause, so I commented some parts of the code to figure it out. So what I've found is that the AlarmManager code is causing it. I already tried changing simulator's version, cleared the project and everything. I'm dealing with this problem for almost 3 days...
Here are a screen shot showing it. Note that there are 2 widgets in the home screen, completely different, but both are the same! I mean... Both are my AppWidget, they should look as the lower one, but with 2 TextViews... The 2 ImageButtons are there, but they don't always show. :/ http://www.flickr.com/photos/76149280@N08/8169290591/in/photostream? So, my question is: what do I have to do to make it work? Do I have to create a "service", do I have to change same code, even use another thing instead of AlarmManager or what? P.S.: I already asked on Stack Overflow ( http://stackoverflow.com/questions/13322168/alarmmanager-destroying-an-appwidget-android-sdk ), but noting...
