ObjectiveRecent research on the implementation of Android push, studied for two days a night, with a little harvest, write down both for sharing, but also to spit groove. What needs to be explained is that some things are biased to the bottom of the hardware and communications industry, I am ignorant of these, can only speak their own understanding.Why study Android
