I installed Android Studio, but it’s missing in the menu. Where placed Android Studio in the system?
How did you install it?
I would guess it would be under .bin but as said just guessing.
By installer from https://developer.android.com/studio#command-line-tools-only
From the page you linked
Command-line tools are included in Android Studio. If you do not need Android Studio, you can download the basic Android command-line tools above.
Maybe install from the AUR?
yay -S android-studio
Fixed, It just installs in the folder from archive.
