Question

I have a class which is used to get media file thumbs. This Loader like class starts an AsyncTask for every ImageView (is called in SomeAdapter#getView()). The task itself does a lot of things, and one of them is calling DiskLruCache, but when the SD card is unmounted, while the tasks are still running the application crashes.

I know how to register if the card state is changed.

So I need an approach how to stop all the running tasks. Any help would be nice.

Answer 1

just iterate through all list & use the following which will cancel all running asynctask.

if(myAsyncTask.getStatus().equals(AsyncTask.Status.RUNNING))
 {
     myAsyncTask.cancel(true);
 }
