How to downgrade Android Emulator

Google support said I could download old Android Emulator versions as follows:

http://dl.google.com/android/repository/emulator-darwin-4266726.zip (for Mac) http://dl.google.com/android/repository/emulator-windows-4266726.zip http://dl.google.com/android/repository/emulator-linux-4266726.zip

Basically, just put the # (the one in major.minor.patch-#) along with darwin/windows/linux if you'd like to download any previous build.

To install on my Mac computer, I did as follows:

1. Download http://dl.google.com/android/repository/emulator-darwin-4266726.zip via Chrome into ~/Downloads

2. Backup the main emulator directory: mv ~/Library/Android/sdk/emulator ~/Downloads/emulator-backup

3. Replace the main emulator directory: mv ~/Downloads/emulator ~/Library/Android/sdk/

4. Restart Android Studio

After that, the Android Emulator version was downgraded to 26.1.4-4266726.

1. Download an older version of emulator from emulator-windows-5395263.zip and replace it with the existing emulator in ..AppData\Local\Android\Sdk\emulator.
2. Restart the Android studio and in terminal run the following command emulator -avd avd_name -gpu mode, and this will initialize emulator. Mode can be host, guest.. etc For more clarification visit the following link
