On top of what SOB said, this is a bad idea - don't block the user from doing anything, especially if it's going to take a long time. If I press back while you're doing some long-running operation (presumably with a progress dialog running) I expect that operation to cancel out - not to sit there trying to finish what it started. If you ignore that and make me wait or hit the Home screen to exit your ongoing process, you can be fairly certain your app will not be installed for long...
