I have implemented Bluetooth in several of my projects where the Android device is the user interface to a custom device with a Bluetooth module using the SPP profile (serial port replacement). But I want to clean up my code and make it more robust. Since I expect to be doing more of these projects in the future, I would like to modularize my Bluetooth Service so that it does not depend on the client class code in any way. I've got a Service working, complete with a thread to read Bluetooth data and deliver each packet of data to the client (which is generally a local Activity). But my method of delivering data back to the client is by means of a handler in that client. That means my Bluetooth Service code needs to depend on the client code. I want to get away from this method for that reason. The Binder interface when the Activity binds to the client is fine for the client calling the Service. But I can't find a similar lightweight method for the Service to communicate with the client (such as when it receives a packet of Bluetooth data). My Bluetooth thread that reads the data can post to a handler to get on the UI thread. But then I am stuck. If I could create another Binder in the opposite direction, that would be great. The client would just create the instance of Binder and my Service could call a method in that Binder without have to know anything more about the client class. But how can I pass a Binder created in the client to the Service? I don't think I can do it in the Intent passed in with bindService, because a Binder is not Parcelable, so it cannot be added to the Intent with putExtra.
I know that Messenger and AIDL exist, but I prefer the lightweight methods for performance reasons. Is there something I am missing that seems to make this job so hard? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
