We use custom AsyncTasks for networking operations that will add extra data/params when calling our endpoints. In most cases, we use them normally by calling Task.execute() to trigger doInBackground() and onPostExecute().

However, in an exceptional case, we want the AsyncTask to block so that we can wait for the return value of the network call. In this case we use get() instead of execute() while running on a worker thread.

However- when using get() instead of execute(), the call just throws a TimeoutException, and it doesn’t seem that doInBackground() is called at all. As it turns out, I ALWAYS get this TimeoutException unless I actually call Task.execute().get()

My problem- because this is a blocking call, I need to run on a worker thread (so I am running on an annotated @WorkerThread method), but because I need to call execute() I am getting warnings that execute() needs to be called from the main thread.

 void cancel() {
            synchronized (LOCK) {
                mmIsCanceled = true;
                close(mmSocket);
            }
         }
