Android Studio guest hasn't come online in 7 seconds

When I first start the emulator in Android Studio I get an information message,

> guest hasn't come online in 7 seconds retrying

I am curious as to how to stop this because while it is on my screen for about 40 seconds I cannot do anything in the emulator.

Actually 'Cold Boot Now' may work in this situation

I had the same problem. Selecting Cold Boot Now in AVD manager solves the problem.

But I have to open AVD manager each time when I want to launch Emulator and I just want to click on Run app button and select device, without opening AVD manager.

To solve this: open AVD manager -> Edit device -> Show Advanced Settings -> Boot option -> select Cold Boot instead of Quick boot.

tools->Android->AVD Manager

Choose the device then Cold Boot Now

maybe it's bug from intel haxm 6.2.1, because after i update i got same problem.

I solved by recreate emulator and testing again

I managed to solve this issue by updating the .ini file manually. (I was not able to find a corresponding setting in the GUI.)

The location of the .ini file, relative to your home directory, is:

~/.android/avd/MyDevice.avd/config.ini

where MyDevice refers to the configured device name.

Depending on your operating system, you may find your home directory according https://en.wikipedia.org/wiki/Home_directory.

Change the entry within config.ini from no to yes:

fastboot.forceColdBoot=yes

1. I specified AVD memory 2048 Mbyte instead of 1536 Mbyte. Things started to work again. (I'm developing on macbook.)
2. I tried "Kuldeep Chandel" solution which is to duplicate AVD and my app runs again too. Because of that I specified RAM again as 1536 Mbyte. Guess what... It worked...

I think AVD confuses to handle things and we need to duplicate the current AVD, and use it instead of the problematic one.

In "Your Virual Device" - Click on Duplicate OR Duplicate your Device. It will work like Charm.

I faced this issue on using Android API 28 emulator with Android Studio 3.0.1. Android API 28 requires Studio 3.1 and above. Once I updated Studio to 3.1.4 and Android Emulator to the latest version, it worked.

Seting default settings for problem device from Android Device Manager resolved issue for me.
