I have been testing MoodleMobile 3.1.3 on Android device and getting error when I try to open SCORM content. There was no such error on previous versions, but on 3.1.3 Android version is giving the error. I am able to open same SCORM content on iOS with Moodle Mobile 3.1.3 version.
I found a bug on tracker: https://tracker.moodle.org/browse/MOBILE-1666
Do you also get the same error on your Android device? Is is platform based or Android device/version based?
