If you just typed “android 40 emulator” by mistake and actually want Android 14 (API 34) or Android 4.4 (KitKat):
Short answer: Use it offline.
Android 4.0 no longer receives security patches. The last security bulletin for ICS was released in October 2016. If you connect your emulator to the internet to test a modern website, you are effectively exposing a Windows XP-era security model to the web.
Best Practice: Run the emulator in a "NAT" network mode (default) or an isolated virtual network. Never log into your real Google account on an ICS emulator; attackers can extract your OAuth tokens via Stagefright vulnerabilities. | If you want

Our Recommendation: If you are a developer, use Android Studio AVD with an ARMv7 image for API 15. If you are a gamer nostalgic for Temple Run, use Genymotion for the butter-smooth frame rates. From host terminal: # Send battery low telnet
