How to Run Android Studio Emulator on AMD processor

New to android. This blog lists the summary of hacks and tweaks that I am to implement to successfully develop Android App. The problem I faced:- I could not run Android Studio Emulator on AMD. Thanks to Stake Again for this wonderful suggestion:- open Android AVD Manager: Tools -> Android -> AVD Manager and create an emulator: -Create Virtual Device -Choose any hardware -Now in system image you need to click on the "Other Images" tab -Select an image to install.  IMPORTANT : Notice that for AMD in the "ABI" column it has to say:  ARM EABI v7a  or  ARM 64 v8a -Install it and restart Android Studio This works for me.
