AVD manager disabled in Android Studio


I’m new to the nativescript. I installed nativescript step by step and I have a question about running android emulator.
I want to setup android emulator by this document:

But I can’t find AVD manager located in Tools > Android > AVD Manager in my android studio. My android studio doesn’t have Android Menu under Tool menu.
And the AVD button in android studio toolbox is disabled in my android studio.

I searched but I can’t find any solution. How I can do?


make sure that ANDROID_HOME and ANDROID_SDK_ROOT environment variables are correctly defined. and restart your Android studio in administrator mood if you are on windows.
