I have seen this issue and i don't have any idea why it's happening. When i stop application from ddms under device tab it doesn't stop it appears again even thought i saw it gets closed on the device but it shows again and i have to stop it again and again then its don't appear again.
So what's the problem there is there are multiple instance of application run there or it start again when i stop it?
Note: i am using an intent service which runs under while(true) loop (I am thinking may b that's why that behavior happens)
