ParseUser and ParseObject on streams call ANR

Question

ParseUser and ParseObject on streams call ANR

I have a problem with my android app. When the application tries to save the ParseObject, sometimes it will block the UI and generate an ANR. According to the traces.txt generated, only one of the methods I wrote is involved, i.e. saveClimbing. This method simply calls onSaveBackground on the ParseObject:

public static void saveClimbing(final ParseObject p_climbing, final Climbing l_climbing){
p_climbing.saveInBackground(new SaveCallback() {    
                @Override
                public void done(ParseException ex) {
                    if(ex == null){
                        //no problems
                        l_climbing.setSaved(true);
                        ClimbApplication.climbingDao.update(l_climbing);
                        Log.i(getClass().getName(), "Climbing correctly saved in Parse");
                    }else{
                        l_climbing.setSaved(false);
                        ClimbApplication.climbingDao.update(l_climbing);
                        Log.e(getClass().getName(), ex.getMessage());
                    }

                }
            }); 
}

Another method involved is ParseUser.saveCurrentUserAsync and it causes hunger, but I cannot figure out when it is called and it is causing that. Am I doing something wrong?

EDIT : In the meantime, I also save the ParseUser object using the saveInBackground method elsewhere in my code. It seems that the ANR is called while the ParseUser object's saveInBackground is executing and the saveInBackground called by saveClimbing is trying to execute. ANR only happens occasionally, not every performance. Am I doing something wrong?

EDIT : This seems to be a bug ( https://developers.facebook.com/bugs/591538734311827/ ). I'm going to try the new Parse SDK single to see if the dead end is gone.

Solved: I was using Parse Android SDK v1.7.1 which has a bug. This error causes a deadlock and sequentially locks the UI and generates an ANR. A bug has been fixed in the new version 1.8.0.

ParseUser and ParseObject on streams call ANR
