Error initializing ADB: Unable to create Debug Bridge: Unable to start ADB server

I need some help with this error. When no other of these questions are helping me, then this means I need to remove and reinstall Android Studio..

Here's the error:-

Error initializing ADB: Unable to create Debug Bridge: Unable to start ADB server: adb server version (36) doesn't match this client; killing... could not read OK from ADB server * failed to start daemon error: cannot connect to daemon 'C:AndroidSdkplatform-toolsadb.exe start-server' failed -- run manually if necessary.

There are a couple of solutions for your question depending on what exactly is causing the problem.

So, just follow the following steps.

Step 1:- Close Android-Studio.
Step 2:- Open Command prompt or win + r, type cmd and press Enter.
Step 3:- Navigate to your platform-tools, in most of the cases the location is:

cmd

platform-tools

C:Users[user]AppDataLocalAndroidandroid-sdkplatform-tools`


but in your case, the location is:

C:AndroidSdk


Step 4:- Type adb.exe start-server, Press Enter
Step 5:- Open Android-Studio again.

adb.exe start-server

Android-Studio

The problem should be solved!

If the problem persists, then follow these steps-

Step 1:- Close Android-Studio.
Step 2:- Press Alt + Ctrl + Del on your keyboard, then choose Start Task Manager.

Android-Studio

Start Task Manager

Windows Task Manager opens.

Windows Task Manager

Step 3:- Go to the processes tab.
Step 4:- Look for adb.exe and select that.
Step 5:- Press End Process.
Step 6:- Open Android Studio again.

processes

adb.exe

End Process

Android Studio

That's it. Now your problem must be solved!

But if the problem is still there (which I don't think will happen), then there is something wrong (or might be missing) in your platform-tools.

platform-tools

To fix that, delete platform-tools from your computer, then download them again from Official Android Developer website

platform-tools

Extract the downloaded file.

Now place the extracted file, where platform-tools were located before deleting.

platform-tools

Default Location of platform-tools is

platform-tools

C:Users[user]AppDataLocalAndroidandroid-sdk


But in your case, the location is

C:AndroidSdk


I spent around a complete day to look for the solution but couldn't find an exact one.
Finally what i did was that I uninstalled my antivirus and after that it worked like a charm.
So, here I shortlist the steps to check whether you are solving for the correct problem or not:-

adb start-server

I've faced a similar problem and noticed the adb was missing from the platform-tools. This
SO answer helped me to fix that by reinstalling the platform-tools package.
