Android8.1 and 5.1 versions recognize sdcard and U disk and create file solutions

Overview

Recently, I was writing test tools under Android, and seeing the different APIs of various versions in Android, I really hope that Qt will work harder in cross-platform. Well, for the Android 8.1 system, if we need to mount a U disk or external sdcard, we need to use reflection to handle it. In addition, in order to automatically recognize this mounting behavior, we also need to implement a broadcast reception器BroadcastReceiver.
