Joe Huang from ADF Mobile Product Management answered a question on OTN regarding changes in Google Play that cause ADF mobile applications to fail deployment if accessed from a tablet. The OTN question and answer is referenced from this link: https://forums.oracle.com/thread/2575378
However, Joe went the extra mile and wrote a blog summary of what happened at Google Play and how you can fix this for current ADF Mobile applications (up to version 11.1.2.4, as I expect a fix to be added to any future versions of ADF Mobile): https://blogs.oracle.com/mobile/entry/android_device_permissions_and_form
