Android AVD, No Target Selected

I am trying to create an AVD, but after selecting the target also, it is showing "No Target Selected".

Why is my AVD not working?

On ChromeOS, Android Virtual Devices (AVDs) might fail to launch because the libnss3 dependency is missing. To launch the AVDs successfully, run sudo apt install libnss3 to manually install the libnss3 library.

Why AVD Manager is not working?

SDK Build Tools are not installed If it fails then you may have to install it again. You look at the build tab at the bottom of the screen, it will display the error message and option to install the Build tools. Install it and you should be able to see the AVD Manager. Another way is to go to the SDK Manager.

to solve the problem. install one of CPU System Images. for example: ARM EABI v7a System Image
