Android app blacklist and whitelist

When the Android device system works normally, many services run in the background. The background Service is automatically killed only when the system memory is insufficient.
During the development of the Android OTT box project, the network set-top box running memory of 512 MB/1 GB is insufficient. To improve the smoothness of the system, the app blacklist and whitelist function is added during firmware compilation.

After the Android system is turned on, A BroadcastReceiver boot broadcast is sent,
