     * <p/>
     * <p>All work that might turn the NFC adapter on or off must be done
     * through this task, to keep the handling of mState simple.
     * In other words, mState is only modified in these tasks (and we
     * don't need a lock to read it in these tasks).
     * <p/>
     * <p>These tasks are all done on the same AsyncTask background
     * thread, so they are serialized. Each task may temporarily transition
     * mState to STATE_TURNING_OFF or STATE_TURNING_ON, but must exit in
     * either STATE_ON or STATE_OFF. This way each task can be guaranteed
     * of starting in either STATE_OFF or STATE_ON, without needing to hold
     * NfcService.this for the entire task.
     * <p/>
     * <p>AsyncTask's are also implicitly queued. This is useful for corner
     * cases like turning airplane mode on while TASK_ENABLE is in progress.
     * The TASK_DISABLE triggered by airplane mode will be correctly executed
     * immediately after TASK_ENABLE is complete. This seems like the most sane
     * way to deal with these situations.
     * <p/>
     * <p>{@link #TASK_ENABLE} enables the NFC adapter, without changing
