My OS is ubuntu 18.04 and I installed Android-Studio 3.4 using sudo apt ~and I started getting this message whenever I run terminal. So, I uninstalled Android-Studio hoping this message disappears. And I again install Android-Studio using ‘Ubuntu Software’ which is built-in installer. But, I still get this message:

Android: command not found. 

Also, my lenovo(8 giga ram) laptop gets easily frozen on Android-Studio.

The following is the output of inxi -Fxx:

Could someone make this message(Android: command not found) disappear for me?
