“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

For anyone who is having the issue now and non of the solutions worked. Try this:

I was having the same issue and it was actually caused by android Q preview. I created a device with Pie and everything just works.

Answer 2

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"

Answer 3

I had a similar problem when updated my android studio. Somehow it changed my SDK path. I just changed it to my updated SDK path and it worked.

Android Studio -> File -> Settings -> Appearance & Behaviour -> System Settings -> Android SDK

Here you will find Android SDK location just click on edit link in front of that and browse and select the Android SDK from the file browser. Select and click on Apply.

Select AVD manager and start Emulator. This solution worked for me.

Answer 4

Try this.

Click on App-->Edit configuration

choose "Specified activity".

Then in activity, choose your main activity(or whatever name you gave it), then click Ok.

Then in "target" choose "open select deployment target dialog".

Click "Apply" then "Ok".

Answer 5

First delete your exiting emulator than recreate it. Now run again hope it will fix your error.

Answer 6

• first delete your AVD from tools>avd manager
• close android studio and restart computer
• open android studio click on run button on toolbar and click on create new virtual device from there

worked for me
