Error:Unable to obtain debug bridge in android studio

Question

After updating Android Studio to 2.0 l am getting this error unable to obtain debug bridge and Android Device Monitor does

Answer 1

I am also running the same problem when update android studio from 1.4 to 1.5 stable version. When I run adb command from terminal then i found following error :

bash: ./adb: cannot execute binary file: Exec format error

After R&d I found that this error occurs due to unsupported architecture. In my case:

I am using ubuntu14.04 LTS 32-bit. I observed that after updation, lib folder under platform-tools converted to lib64. I think above error occurs due to 32-bit architecture because after updation 32-bit support removed.

For permanent solution upgrade you system to 64-bit architecture. Quick solution is to replace the updated platform-tools folder with old one that containing the lib folder instead of lib64.

I think 32-bit architecture support for android development stopped by google for future releases. But I am not sure.
