Thanks a lot for response, Hackborn. My case is that a native process have to send some messages to a java runtime service to broadcast some notification. So it's going across process.
I know I can use socket, but I want to know if the Binder can be used in this case. In other words, can binder be used as a new full duplex IPC mechanism or it's only suitable for a client-server mode.
