Subject [jira] [Commented] (CB-12560) InAppWebBrowser throws NullPointerException when attempting Callback
Date Wed, 26 Apr 2017 01:35:04 GMT


ASF GitHub Bot commented on CB-12560:

Github user filmaj commented on the issue:
    @dblood in [CB-12560]( you showed some
pretty detailed logs and mentioned a monitor script that leverages inappbrowser to check a
URL every second. Could you share this code, or a rough semblance of it, so that we could
try to reproduce?
