Implement IPC communication on the android Upper Layer

The android upper layer implements the IPC Communication Server, and directly goes to the Code:

Package COM. KZ. server; import android. app. service; import android. content. intent; import android. OS. bundle; import android. OS. handler; import android. OS. ibinder; import android. OS. message; import android. OS. messenger; import android.

The main process is the above two categories, some interfaces are not published, and reference materials are the topics of services on the official website.
