Obviously I used Tweak, (in addition to this I also installed Apkenv-QML), I created, from Tweak, the Angry Birds and Ftuit Ninja shortcut (obviously the game with right name were in the right folder, but when I clicked on one of them, the spinning indicator on icon turns, but nothing happened, and the same happened when created and started a game from Apkenv-QML.
For this I tried to run it from terminal, to know what was the problem.. and the problem is the error message described in my previous post.
