Question

Android Studio is unable to install an application throwing the following error:

adb server version (40) doesn't match this client (41); killing

I tried answers from this stackoverflow question but they didn't work for me.

Answer 1

What I did to solve this issue is that,

1 - download the latest version of platform-tools from here platform-tools,
2 - in your computer go to C:\Users"YOURCOMPUTERNAME"\AppData\Local\Android\Sdk
3 - change your old platform-tools file to platform-tools77 just to back it up
4 - Put the new platform-tools you downloaded from step 1.

That all ! if it not works download another version (older) from same link and try again till you find the one match your software.

Answer 2

I have Android SDK and tools already installed and adb is present in $HOME/Library/Android/sdk/platform-tools/adb

In my case, just removing adb from my /usr/local/bin/adb which I got from adb version using rm /usr/local/bin/adb solved the issue.
