“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

None of these solutions worked for me. After removing and installing the emulator from scratch several times, and also SDK Tools, I saw under developer options in the emulator that USB debugging was not active.

• Settings
• About Emulator Device
• Click several times on Build Number until it says that you are a developer
• Go back
• Get into developer options
• Put a check on "USB debugging"
