Purpose: used millet mobile phone have the function of a shortcut to open the flashlight
1. Press power button twice to open flash
2. Then press power key to turn off your flash twice
How convenient, this function is to go to the toilet at night touch phone press 2 times power key to open the flashlight can complete one hand operation
Now in huawei mobile phone without this function with unaccustomed to unlock the screen every time to find a flashlight to open again, need hands to finish operation
May even if someone don't understand how hard it's not the things with their hands to do more than just the 2 steps things there is no need for this thing entanglements
But my idea is:
1. Want to ask, the train of thought to solve the problem of the
2. You can take to get to know mobile phone application development train of thought and method (before have no contact with mobile phone app development)
Thank you very much!

can't, this is all belong to internal functions as a mobile phone is not a function of the app

There are two obstacles: 1, the default start and has been running the service, listens for keys or receive events. 2, open the flashlight function, the number and the hardware control, still do not know whether mobile phones can provide public services and permissions,
