-// Call RequestAppProcessList() / RequestSystemProcessList() on the main UI

-// [System Process]
-// The system process here is defined by the scope. If the process is produced
-// under system_server in Android, we regard it as one of Android app process.
-// Otherwise, the processes that are introduced by init would then be regarded
-// as System Process. RequestAppProcessList() is responsible for app processes
-// while RequestSystemProcessList() is responsible for System Processes.
