How can I create a system service in framework base package ?

[Huy Hoàng Nguyễn]

I want create a sample system service in framework/base with system permission, it can be the same with LocalTransport service

But my sample service is keeping removed by ActivityManager and cannot run. This is the logcat I collected:
