$ sudo apt install google-android-emulator-installer
This package will download Google’s Android emulator binary package, create a Debian package, and install it.
The Android SDK includes an Android device emulator — a virtual device that runs on your computer. The Android Emulator lets you develop and test Android apps without using a physical device.
WARNING: Installing this Debian package causes android-emulator to be downloaded from dl.google.com and/or from other suggested mirrors. The End User License Agreement of this binary package is available at developer.android.com.
