Then write it in a flat file. That works too. There is nothing all that special about this: your app is exiting (finishing); you apparently want to restore some state that was saved from the last time it run; so write it into persistent storage somewhere when you are done and read it back when you start again. You go about this like you would on most other platforms, and we don't have any specific special support in Android for this particular case.
