doInBackground runs on another thread, so of course it can cause a race condition- anytime you have two threads, or a thread and asynchronous events incoming you can have a race condition. You always have to code to avoid them. However the return of values from doInBackground to onPostExecute will not, so you do have a safe way of passing data between the threads without a race.
