“waiting for target device to come online” in Android Studio 2.3

Question

Recently upgraded to Android Studio from 2.2.3 to 2., running on Win10

Emulator stopped working since then. Tried installing other images(25 rev 4)/upgrading for AVD

Answer 1

After trying Cold Boot and other stuff, I removed Android Emulator from SDK Tools, and then reinstalled. But first, I reinstalled HAXM too, because I recalled that I had an error message when installing by first time.

To install HAXM I had to disable Hyper-V on Windows 10, basically running:

bcdedit /set hypervisorlaunchtype off

like stated here: https://github.com/intel/haxm/issues/105#issuecomment-430484231

After that, I reinstalled Android Emulator. It's just unchecking the box, applying the change, checking it again and applying the change. But you can follow more detailed steps here: https://www.technipages.com/android-emulator-stuck-waiting-for-target-to-come-online

After that, I have my AVD running.
