I am new to Android Studio and Ubuntu. I downloaded SPP App from GitHub, and when I tried to open it in Android Studio, I found that the file is not listed in the folder chooser in Android Studio. When I checked the folder containing that file on the hard drive, I found that this folder was marked with a locker sign.
Is the file not getting opened in the studio because it is marked with a locker sign? How to solve this issue?
