Question

I have created a project, which was working fine and had 2 Activities with all the components working fine. I have zip this project and uploaded online . But now if I unzip the same project , i am unable to see the layout and my source code. Basically it showing as if I have created a new Project . For example: I had deleted the Test folders , but they came back when i unzip and opened in Android Studio.
