I've got an old Nvidia Shield Clamshell (the one released in 2013) running Android 5.1. The website claims that Android 5.0 and above is supported.
When I try to start up Launchbox on my shield, I get several different exceptions that I'm including below and then the app hangs on "Loading data". Some of them appear to be about permissions failing, but Andoid indicates that I've given full network access, SD card access, and a couple of other permissions to LaunchBox.
I'm using LaunchBox 0.42 for reference as this was the apk made available in the email.
