ADB Connection Error: Unable to create Debug Bridge: Unable to start adb server: Unable to detect adb version, adb output [duplicate]

Answer 1

Replacing old platform tools fixed my problem too. Thanks "RealDogBoy".

Download the 23.0.1 files with this link: https://dl-ssl.google.com/android/repository/platform-tools_r23.0.1-linux.zip

1. I renamed the old "platform-tools" folder to platform-tools_23.1
2. unzipped the above zip file into the sdk folder.
3. restarted the Android Studio.

Started working fine.
