If the emulator doesn't work with the IDE release you are using, you could revert back to a working version. https://developer.android.com/studio/emulator_archive.

I went through a lot of posts. But none of them seemed to work for me. Every time I tried to start the emulator, the process seemed to be "not responding" after a minute or so. I tried restarting my PC, adb, created new devices, even re-installed Android Emulator, but nothing worked. Surprisingly enough, what worked though was to move the emulator out of Android Studio.

  • Go to Preferences -> search for Emulator -> Uncheck Launch in a tool window

I am using Mac M1 Pro with Android Studio Bumblebee | 2021.1.1

I tried everything here and other questions too, but the only solution for me was to create a new AVD. Also downgraded from Pixel3XL to Pixel2, not sure if it matters. (Kept same android version)

This Worked for me:

GoTo SDK Manager -> SDK Tools -> Check that the android emulator has the latest version and If doesn't install the updates.

I had the same error described here.

Hope This Helps

Click on app: edit configurations;

In Launch Options: choose Specific Activity

In Activity: specify your main class: com.example.budgetapp.MainActivity

And, run.

  1. Open the AVD Manager.
  2. Create a new AVD or edit an existing AVD.
  3. In the Verify Configuration page, specify the Emulated Performance: Graphics change to sofware or hadware

good luck

I was also facing this timeout error. Here is the solution worked for me

Launch Task Manager -> Search for adb.exe in process list->End the process->Try relaunching the emulator it will start.

Although there could be various reasons for this behaviour.... Mostly it may be due to error in system images or the API version you are using

better you download latest system images and make sure the compatibilty of API version you are using.

enter image description here

If problem exists

I would like to suggest some fixes: Try them

1)Uninstall/Reinstall Android SDK to folder.

OR

2) delete the emulator and create another emulator targeted at the appropriate API Level.

OR

3)create a new Virtual Device.

OR

4)set "Max VM application heap size" hardware property to 192 or higher and pick the QVGA skin.

hope it helps.
