You shouldn't need that. The point of AsyncTask is to do things in a
background thread. Hence, use synchronous operations, not asynchronous
ones, from calls originating *inside* AsyncTask's doInBackground().

Why, then, are you using an AsyncTask?

Either write everything as synchronous and then use AsyncTask to move it
to the background, or write everything as asynchronous and get rid of
the AsyncTask. Using an AsyncTask won't make background work be even
*more* background, after all.
