Just updated to Android Studio 4.2.1 on Mac and now emulator no longer works

Question

I just updated Android Studio to its latest version 4.2.1 and the emulator stopped working. Every time I try to launch a new virtual device it crashes and AVD Manager shows me this error:

"The emulator process for AVD Pixel_C_API_30 was killed"

Here is what I have tried so far:

1. Cold boot restart.

2. Deleted and recreated the virtual device inside AVD manager.

3. Removed and re-installed the emulator SDK package (version 30.7.4)

4. Quit and restarted Android Studio as well as the emulator.

5. Created a new virtual device from scratch.

6. Tried several different virtual devices.

All of the above gives me the same exact result: the emulator crashes and AVD manager shows me the error above.

And here is the error I get from MacOS (just the an excerpt of it):

Any ideas? I am on MacOS 10.15.6, Android Studio version 4.2.1, Runtime version: 11.0.8+10-b944.6916264 x86_64

Update: I tried to launch it from the terminal like this:

./emulator -avd Pixel_C_API_30

And I got the following output right before its crash:

Answer 1

All of the answers are too confusing to follow. Replace SDK or upgrade OS. The quickest way I found is to:

Tools > SDK Manager > SDK Tools

De-select Android Emulator, then click Apply. - The Android Emulator will be deleted.

Now, by default the Emulator version shown will be 30.6.5. Select the checkbox and click apply. This version of emulator will be installed.

That is it, just 2 minutes of you time.

Update: 1 Jul 2021 Issue solved with latest Emulator version 30.7.5

Answer 2

I've had the same exact error. It's caused by Android Emulator 30.7.4 in combination with macOS Catalina. You can track the issue here

• https://issuetracker.google.com/issues/191799887
• https://issuetracker.google.com/issues/191805460

The work around that worked for me was upgrading to Big Sur.

Answer 3

I manually reverted to 30.6.5 and it works back again.

Answer 4

you must downgrade emulator for Catalina

1. download emulator 30.7.3
2. unzip emulator-darwin_x64-7425822.zip
3. do command "xattr -rc *" to remove all extended attributes
4. replace your emulator folder(/Users/xxx/Library/Android/sdk)
5. modify package.xml to <revision><major>30</major><minor>7</minor><micro>3</micro></revision>

Answer 5

You can download the emulator and palce it into SDK folder. It worked for me. Here I found the files. How to download android emulator without using android studio

Answer 6

With the help of this link able to downgrade the version to v30.6.5; Now able to run the emulator
