Receiver not registered exception error?

Question

In my developer console people keep reporting an error that I cannot reproduce on any phone I have. One person left a message saying he gets it when they try to open the set

Answer 1

I used a try - catch block to solve the issue temporarily.

// Unregister Observer - Stop monitoring the underlying data source.
        if (mDataSetChangeObserver != null) {
            // Sometimes the Fragment onDestroy() unregisters the observer before calling below code
            // See http://stackoverflow.com/questions/6165070/receiver-not-registered-exception-error
            try  {
                getContext().unregisterReceiver(mDataSetChangeObserver);
                mDataSetChangeObserver = null;
            }
            catch (IllegalArgumentException e) {
                // Check wether we are in debug mode
                if (BuildConfig.IS_DEBUG_MODE) {
                    e.printStackTrace();
                }
            }
        }
