HI Al, I have tried putting the logs & my observations are as follows:
Case 1: when the local service not started up on boot up complete. >From UI Call bindService() to start the service. Since the service is not yet started onCreate() is called followed by onBind() of the local service. From onServiceConnected() UI get the instance of service, register a callback handler(so that service can inform UI once the desired operation is complete) & invoke the desire operation. Once the operation is completed the UI calls unbindService(). In this case the service is killed on unbindService(). Also as mentioned by me earlier in this case the binding / unbinding works multiple times & each time ui is able to communicate with service. Case 2: LocalService is started on boot up complete. On Bootup complete event the service is started by calling startService (). This invokes onCreate() followed by onStart() of the local service. The service is started at this point. On user action UI now invokes bindservice() to bind the service with UI.From onServiceConnected() UI get the instance of service, register a callback handler(so that service can inform UI once the desired operation is complete) & invoke the desire operation. Once the operation is completed the UI calls unbindService(). In this case the service is not killed since stopself() or stopservice() is not called. >From this point on I cannot bind again with the service, i.e. bindService() returns true...but onBind() is never called.
