However, I personally think the callback is good, because the code can be more neat, but it is very troublesome to use the callback. You must declare a function. If this function is a class member function, you have to d

devices currently use USB-based protocols. The equipment supporting MTP on the market has Motorola's Z6, U9, E8 and so on, as well as the Sony NWZ-A81X series. In short, more and more devices are beginning to support MTP. Microsoft Official has a PlaysForSure certification, if your device through the Microsoft test, you will be authorized to give you a PlaysForSure logo.
