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.
