I was also facing this issue. I sort of solved it by calling the below method in my Activity's onCreate()

/**
     * Initialize Push Messaging Service and subscribe to all-users channel
     */
    private void initParsePushMessaging() {
        ParseInstallation parseInstallation = ParseInstallation
                .getCurrentInstallation();
        //You might skip this if
        if (ParseUser.getCurrentUser() != null) {
            parseInstallation.put("user",
                    ParseUser.getCurrentUser());
        }
        if (parseInstallation.getObjectId() != null)
            parseInstallation.saveInBackground(new SaveCallback() {

                @Override
                public void done(ParseException e) {
                    PushService.subscribe(getApplicationContext(),"channel_name",
                            MainHomeActivity.class);
                }
            });

    }

Even though it didn't completely solve my problem but now my app doesn't hang and no more ANR's due to this Parse implementation. If i re install an app and run it now then the app creates a new installation record and remove's the last one. The only problem is that the channel_name is not subscribed on this run but on the next run the channel are successfully subscribed.
