Greetings,
I use a “Tab Bar Application” as base my APP.
It have seven views.
And use a system.SetPreferences and system.GetPreferences how persistence data.
But, in Corona Simulator work fine.
I create a .APK and install in ANDROID AVD, work fine.
The .APK installed from Google Play not work.
Maybe there are some permission missing in usesPermissions?
Best regards.
