I have a Google Nexus 7 that I share with my kids. I am the owner and created a second account for my child. I've found that many games work on my (the owners) account, but will not work on the second users account. One of the apps in question is Unblock me Free. It works great on my account, but on the second users account, it will get to the splash screen and then just disappear. I cannot find any app, user or security settings that could be causing this. Hoping for some insight from this group as to what is causing this. I hesitate to install a root-kit or unlock the tablet unless I can be convinced that's the best/safest way to go.
As far as Android SDK documentation goes:
Hence theoretically speaking, if the app developer had used appropriate methods this app should work normally. In that sense, I do not think you have any better way other than reporting this to the app developer.
Rooting your Nexus 7 doesn't going to solve this issue - in my opinion.
Update: I sent an email to the support team of the app developer quoting this question. I received a reply as:
which in my opinion supports my assumption.
Google Play's Family Library with app and game sharing goes live July 2, 2016.
From the relevant post on the website Android Police:
Family Library and sharing have been a long, really long, time coming on Google Play. In his different app teardowns, Cody has repeatedly discovered strings pointing out to the feature coming to Play Books, Play Movies, Play Services, the Play Store, but up until recently, the only Google entity that had benefited from any kind of family sharing was Play Music and its Family Plans.
But at this year's Google I/O, Google announced that Family Library was coming to Google Play app and games purchases with the new changes taking effect on July 2nd.
What has already changed though are the terms of the Google Play Developer Distribution Agreement. A new section 5.4 explains how a family group, with one manager and different members, can purchase the product once and share it with other members of the family. So starting July 2, any purchases you make on the Play Store will be available for sharing with your other family members.
