Android bindService() notice

There are roughly two ways of using the service in Android,Context.startService() and Context.bindService().

Context.startService(): can be used only by one application.
Context.bindService(): could be exposed to other applications.

Here we focuse on Context.bindService().

bindService() -> onCreate() -> onBind() ->onServiceConnected()-> running.

There is one thing we have to notice.

The onServiceConnected() may not be called immediately and this might cause some problem!
