What is the extension of a Android Studio project file?
android-studio
Solution
Use the `import project` function on the `build.gradle` file in your project root (not the folder itself!) to open the project again in Android Studio.
Problem
What is the Android Studio equivalent of Solution file in (.sln) file in Visual Studio ? I created a project in Android studio and closed it. Now I am not sure which file should I open to reload it into Android studio.
