unable to execute adb in Ubuntu. Downloaded file is meant for x86-64 while I have i686 [duplicate]

Answer 1

Yes, Android Studio aims to support only 64-bit systems.

I used it on 32-bit systems last year, and remember a warning explaining that 32-bit will not be supported in the long-term.

You can follow this "issue" here.

Answer 2

https://dl.google.com/android/repository/platform-tools_r23.0.1-linux.zip is the last 32-bit version. Use that instead.
