“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 lots of attempts, stopping device from AVD(exactly from AVD, not by cross button nor power off button on emulator) and starting build again helped me.
