Question

My application has one service which runs until user pressed exit button. I know giving exit button in android is not good design but in my application it is desired.

In my application I also have a thread to send Http request, download a file and then parse it in background so that UI will not block. In my thread’s run method there are sequential steps (like download a file, then parse it), there is no while or for loop in it.

When user presses exit button, is there any way to stop the background thread if it is running without kill process (using Process.kiil(pid) or System.exit(0)) ?

I have tried AsyncTask also. Whatever in run method of thread, i put it in doInBackground method. When user presses exit button i have canceled asynctask. Cancelling task not stop the background thread completely because after file download it will go in parser to parse the file (i.e. parsing is done in background thread but it at the time of parsing it is not in doInBackground or run method. It will in parsing method of parser class or in Default handler class for parsing.)

From googling I read many blogs and other stackoverflow questions about thread but still I cannot find any solution for it.
Please help….thanks in advance..

Answer 1

Stop thread at instance (when exit event occurred from UI) is not possible without using

Process.killProcess(Process.myPid());
