This is also valid for Ubuntu and other Ubuntu-based distributions.

Anbox is a discontinued free and open-source compatibility layer that aims to allow mobile applications and mobile games developed for Android to run on Linux distributions.
To install Anbox we open a terminal from Applications

From the terminal we write:
sudo apt update
And then we need to install snapd
sudo apt install snapd
We can check the version of snapd that has been installed
snap –version
We are ready to install the beta version of Anbox
sudo snap install –devmode –beta anbox
And now we only have to install android-tools-adb
sudo apt install android-tools-adb
It is time to restart the device to be able to access Android Application Manager from the applications menu.

Now we can download applications for Android and install them in Anbox, to do this we open a terminal again and write the application installation command
adb install My_apk.apk
that once installed will also appear within the Android Application Manager
