Unable to locate adb for Android Studio 3.0.1

Question

Regarding error message: Unable to locate adb .

I followed what people said on other threads but none of them worked. So I uninstalled Android SDK platform-tools in SDK manager. Android studio didn't like me doing that so after 30 minutes I canceled the uninstalling. Now it has been doing "Stopping -Installing Android SDK" and shows my this message: "Cannot run program "C:\\Users\\admin\\AppData\\Local\\Android\\Sdk\\platform-tools\\adb.exe": CreateProcess error=2, The system cannot find the file specified"

I have no idea what to do. I'll put the error message below. Many thanks for any reply.

Answer 1

I got this error when I upgraded my Android Studio from 2.3.2 to 3.0.1, too. It happened because there's no file named adb.exe in adb-path. But now it's solved. I hope my answer could help you.

First, I downloaded the latest version of SDK Tools in: https://developer.android.com/studio/releases/platform-tools.html

Second, I extracted the file into Android Studio SDK's directory (in my case is "E:/SDK/"). But it will rewrite the old files with the new one.

Third, open terminal in Android Studio. run this :

• cd "adb-path" (eg : cd "E:/SDK/platform-tools")
• adb devices

Done :)

Answer 2

Open CMD as Administrator and simply run the command given below:

cd <adb-path> cd c:\Users\Pilot\AppData\Local\Android\sdk\platform-tools\

Then run

adb devices

Answer 3

I had a similar issue. Apparently, My Anti-virus, in my case AVG, blocks the ADB. To solve it, just ignore the error message above. go to your anti-virus make sure adb isn't blocked. restart your android studio.
