Unable to start receiver com.parse.ParseBroadcastReceiver : ConcurrentModificationException

I am getting a crash on Samsung Note 2 with parse sdk version 1.5.1 and below is my Application class code.

@Override
    public void onCreate()
    {       
        super.onCreate();

        try
        {


            Parse.enableLocalDatastore(this);
            // Live acc
            Parse.initialize(this, "XXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXXXXX");

            //Enable to receive push
            PushService.setDefaultPushCallback(this, RespondToPushActivity.class);

            Log.d("System out", "Parse ID----> "+ParseInstallation.getCurrentInstallation().getString("deviceToken"));
            Constants.PARSEID = ParseInstallation.getCurrentInstallation().getString("deviceToken");



            ParseInstallation.getCurrentInstallation().saveInBackground();
        }
        catch (Exception e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }    


    }

Now I got the stacktrace below:

I had the same issue. As it appears in your stacktrace, you encountered a java.util.ConcurrentModificationException when iterating over a LinkedList:

at java.util.LinkedList$LinkIterator.next(LinkedList.java:124)

One solution is to protect your code in a synchronized block or method.

Another solution, which I chose, is to use a collection specifically made for concurrent accesses. In my case I wanted an random accessed list (like ArrayList) so I used instead the java.util.concurrent.CopyOnWriteArrayList provided in Android package java.util.concurrent. I did not find any concurrent access collection for LinkedList but maybe the CopyOnWriteArrayList is enough for you. It is specifically made to read the list a lot and update it rarely.

Wwhile I cannot guarantee I found the exact right solution (it is a concurrent access issue, so this is hard to test), I do not have the bug any more, I consider my issue resolved.

Try fully uninstalling the app from your phone and re-deploy it. I just had the same issue and uninstalling (include deleting cache and configs!) fixed it for me.

Did you make sure to register your custom Application class in the Android Manifest?

<application
        android:name=".MyApplication"
...>
.

</application>
