I downloaded several projects ready for study purposes in Android Studio. They are projects like calculator, agenda, etc. But I can not open them in Android Studio in the way that, I think, is correct. I can open separate files, such as xml ... But I do not know how to open the whole project.
In summary, is there any way to open the downloaded project just as we do, for example, in Visual Studio when running the .sln file?
As simple as it is, I searched extensively and tried many times without success.
Thank you!
