“waiting for target device to come online” in Andr

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 but nothing seems to work. After running gradle and showing "waiting for target device to come online" in task bar nothing happens and program doesn't run.

Kindly help

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.

Answer 2

Upgrade your Display driver ... this worked for me!

Answer 3

if you docker is running you should close it.

Answer 4

I tried doing a “Cold Boot Now” in the device, but got an error saying: AVD Pixel_API_24 is already running. If that is not the case, delete the files at /.android/avd/Pixel_API_24.avd/*.lock.

After deleting a .lock file in the suggested folder the “Cold Boot Now” worked and the device was back to normal.

Answer 5

maybe you do not have SDK of your simulator,please check File->Settings->Appearance&Behavior->SystemSetting->Android SDK

Answer 6

I had the same problem ,I was using

Linux LinuxRobot 4.14.0-kali3-amd64

and getting this

host doesn't support requested feature: CPUID.80000001H:ECX.abm

and this message

waiting for target device to come online

Solution Close debugging and current emulator then

Open Avd Manager ,you will be able to see your device there then click on play button

Or Try Cold Boot

Open Android virtual device manager,click on drop button after select cold boot. read this
