Use of android.os.Binder for the organization of asynchronous interaction in the Android

1 year, 7 months ago
One of natural and first tasks when developing under the Android – the organization of asynchronous interaction. For example, the appeal to the server from some activity and display of result on it. Difficulty consists that for access time to the server other activity or other application can be atop open, initial activity can be irrevocably complete (the user clicked Back) etc. Here we received result from the server, but activity "is inactive". Under "is active", depending on circumstances, it is possible to understand, for example, what is between onStart and onStop, onResume and onPause (or, as at us in the project, between onPostResume and the first of onSaveInstanceState and onStop). How to understand, activity finally (and the result needs to be given to a garbage collector) is complete or is only temporarily inactive (the result needs to be kept, and to display as soon as activity becomes active)?

Surprisingly, but in documentation, the Internet, at personal contact I never met correct and is acceptable a universal method. I want to share non-paid a solution which we apply two and a half years in mobile Internet banking. The application is installed (as part of larger system) at several hundred banks, about one million users at the moment have.
