Few days ago I tried to install two version of Google Play Store simultaneously. I used APKTool in order to change package name (it's a standard procedure for this purpose). I aligned and signed new apk and I managed to install it. But modyfied Google Play Store gets stopped (standard error, Google Play Store has been stopped) when I'm trying to execute Store. My question is how to have two Google Play Stores installed simultaneously? Of course if it's possible at all.
