For using RoboVM on OSX, I need to edit a file called info.plist, which resides inside the contents of the application called Android Studio.
Last year I managed to edit the file for Android Studio 1.5 (right image), but I now installed Android Studio 2.13 and I didn't succeed (left image).
It seems that the contents of this application are read only. How do I edit this file? I only need to change one value.
