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


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:\Android\Sdk\platform-tools\adb.exe start-server' failed -- run manually if necessary.

Solution

  • There are a couple of solutions 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:

    C:\Users\[user]\AppData\Local\Android\android-sdk\platform-tools
    

    but in your case, the location is:

    C:\Android\Sdk\
    

    For Mac users the path is

    /Users/[user]/Library/Android/sdk/platform-tools
    

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

    For Mac the command is just adb start-server

    The problem should be solved!


    If the problem persists, then follow these steps-

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

    Windows Task Manager opens.

    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.

    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.

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

    Extract the downloaded file.

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

    Default Location of platform-tools is

    C:\Users\[user]\AppData\Local\Android\android-sdk\
    

    But in your case, the location is

    C:\Android\Sdk\
