Ran it on a Droid running Android 2.2. I entered a bunch of information for a team and pressed save. It gave no indication that the data was saved. I pressed back to get back to the main menu to load the team and found that the list was empty. So, it seems that data is not being saved correctly.
Also, you have a force close situation if the user clicks 'load team' without having a team selected or having an invalid team number.
Another minor gripe is that your icon does not follow the
Android standards. You'll probably want to come up with a simple design and make it look a little more professional.
