For instance in Google Music, if you are playing music then the the notification cannot be swiped away. However if you pause the music it can. This is completely different to how it is implemented on Android 4.4, where the notification starts only when you leave the app and removes itself when you go back into the app. I can't see how to implement

问题 my app crashes when it comes back to foreground after some time playing with others applications and I can't find out how to fix it. My app has a splash screen activity where it loads some data from web services and put it in global static variables declared in a class extending Application, as explained in this SO question.

问题 Update : I have not found a true solution to the problem. What I did come up with was a method of automatically reconnecting to a previous bluetooth device anytime the connection is lost. It's not ideal, but it seems to work fairly well. I'd love to hear any more suggestions regarding this though. I'm having much the same issue as in this question: Service being killed while holding wake lock and after calling startForeground including the device (Asus Transformer), the length of time before
