  • Android Studio 4.2.1 Build #AI-202.7660.26.42.7351085
  • JDK: 11.0.8
  • OS: Mac OS X 11.5.1
  • Android Studio Plugin : HMS Toolkit version: 6.0.0.300
  • SDK tools : Android SDK Platform-Tools 31.0.3 (latest)

Check adb using terminal.

adb version
  • Android Debug Bridge version 1.0.41
  • Version 31.0.3-7562133
  • Installed as /Users/mar***/Library/Android/sdk/platform-tools/adb

I had research HMS Toolkit is support Android Studio version until 4.2.1
Reinstall Android SDK Platform-Tools.
Why I had try.
Reinstall Android SDK Platform-Tools.
Reinstall HMS Toolkit.
Reinstall Android Studio.
Problem still occured.

Anyone faced same question? Any solution?

The bellowing is my path, for easy to see, I split into multiple line, default is one line.
I using zsh, references ~/.zshrc.
echo $path

The log reads: Plugin to blame: HMS Toolkit version: 6.0.0.300
… and then it literally continues with cant not found adb path:

I’ve just tried to install the HMS Toolkit on Android Studio version 4.2.2, which complains on startup (but it still kind of works, except some buttons not being well-clickable).
Make sure it downloaded it’s resources (this may have been blocked by local firewall) – and make sure that adb is on PATH.
