Android Studio - ADB not responding. If you'd like to retry, then please manually kill “adb” and click 'Restart'

Question

So I've wanted to run a basic app I just made and then this message popped up.

ADB not responding. If you'd like to retry, then please manually kill " adb " and click ' Restart '

I did try a couple of fixes I could find but nothing worked so far, any help is greatly appreciated.

I am running Linux 15.10 32BIT

Edit: Everything I tried:

1)

Use this command:

adb kill-server

followed by:

adb start-server

2) Go to Tools -> Android -> Enable ADB entegration . Untick this. Make sure its status appears as unticked. Now go to task manager and killed the process adb.exe

3) Also reinstalled Android Studio and Java SDK

Answer 1

C:\\Users\\sdk\\platform-tools files are missing in the platform-tools. Complete the missing files will be resolved(It must be like the second image)
