If it must implement with AIDL? And please kindly provide an example, thanks.
EDIT: There are several solutions, Does anyone know which is better?
回答1:
You might be looking for the ResultReceiver class (http://developer.android.com/reference/android/os/ResultReceiver.html).
You extend it, pass it along with the intent you invoke the Service with (it's parcelable), then when your task completes in the Service, you call the ResultReceiver's onReceiveResult() method with the results.
