i want upload number of files stored on android device seems stuck in doinbackground method of asynctask. no errors. dialog popsup , stays active eliminated dialog , no effect. other part of project decode json files uploaded , store them in database thats later.

you not implement @override onpostexecute.
modify onpostexecute assignature this:
@override protected void onpostexecute(void result) { this resolve problem. happening: not overriding onpostexecute asynctask method, creating new one.
