Cannot cancel running AsyncTask in AsyncTaskLoader

Question

I want to cancel running AsyncTask (in AsyncTaskLoader) when the user clicks the home button. Here is what I created so far:

package cz.davidliska.android.lo         


        

Answer 1

public boolean cancelLoad() {
    ...
    boolean cancelled = mTask.cancel(false);
}



        @Override
        public Date loadInBackground() { // AsyncTaskLoader only
            Log.d(TAG, "Loader.loadInBackground()");

            try {
                // there will be some HttpClient.execute()
                while(true) {
                    Thread.sleep(100);
                    Log.d(TAG, "Loader.loadInBackground() still running");

                   if(cancelled)                 <---------
                      return new Date();         <----------
                }

            } catch (InterruptedException e) {
                Log.d(TAG, "Loader.loadInBackground() interupted");
            }
            Log.d(TAG, "Loader.loadInBackground() finished");
            return new Date();
        }
