no, not really…
I wanted to know whether test versions of app should have to be signed being able to run them on my real device.
I see if I want to publish them via store – http://v-play.net/doc/vplay-publishing.html – there is a step “Create a distribution certificate and a private key to sign your game apk” to be performed. it is missing from steps described here: http://v-play.net/doc/vplay-deployment.html
So, is signing required before publishing only?
