Nowhere on the app's page does it say it is a test version, or why it is blocked from every device, nor give a G+ link. Here is an article which is where I saw this first, along with links to install: http://venturebeat.com/2015/02/27/vlc-gets-first-major-relea...
This is all very confusing, and quite frankly a rather hostile user experience.
As for poorly edited, here is the press release: http://www.videolan.org/press/vlc-2.2.0.html
It says the Android version is released today. Note no mention that Android is in beta, limited to testers only or anything similar.
I have no issue with VLC and like it well. They have done a great new release, which is welcome. They even went to the trouble of writing a long press release, getting quotes, and apparently talking to people at venture beat.
But then prevent installation of the android version without any clue as to why, undermining that previous effort.
That is usually the most common reason for Play Store errors like that.
No, it's just the beta version. You need to be in the G+ community.
I get told "This app is incompatible with all of your devices." and for each device says "This item is not compatible with your device". I have 7 different devices on my account, most with Android 4.2+ which is marked as the minimum version.
