android - Pjsip Crashed on RegState callback

In my class that extends SipAccount class I've onRegState() callback which i receive frequently I've notice that after few callback later at any callback like 4th or 5th time it crashes.

this is the code from onRegState() callback 

 @Override
    public void onRegState(OnRegStateParam prm)
    {
        Log.d(TAG, "onRegState...");
        PresenceStatus prsenStatus =  new PresenceStatus();

        if (prm.getCode().swigValue()/100 == 2)
        {
            Log.d(TAG, "Going online!");
            listener.onLogIn(true);
            prsenStatus.setStatus(pjsua_buddy_status.PJSUA_BUDDY_STATUS_ONLINE);
        }
        else
        {
            Log.d(TAG, "Going offline!");
            listener.onLogIn(false);
            prsenStatus.setStatus(pjsua_buddy_status.PJSUA_BUDDY_STATUS_OFFLINE);
        }

        try
        {

            sipAccount.setOnlineStatus(prsenStatus);

        }
        catch (Exception e)
        {
            e.printStackTrace();
        }

    }

This is the log from pjsip client.

Preface

I was also struggling on this problem for several months and got the same on the real-world app usage (crashes form the play market). And used your code to handle registration results.

The difficult was that we couldn't experience that issues during our tests on any of our devices but our users got it approx 500 crashes per 1000 installs (very high).

Initially I was dealing with Pjsip from UI thread, then I tried to create my own thread for the Pjsip (with uaConfig.setThreadCnt(0) and uaConfig.setMainThreadOnly(true)) but it failed to work at all, or I don't know how to do this right and there is no clue about it anywhere. Then I moved all our business logic from UI to worker thread and worked with Pjsip from worker thread. Nothing helped and the issues were the same.

Finally yesterday we were able to catch this issue and at the same time we had Pjsip logs turned on level 9.

And here is the full log for this crash with preceding info (I've replaced actual server credentials for obvious reason):
