1. Solution 1: Set up ADB Environment Variables

When you see the error “ADB_Vendor_Keys” not set, it means that your system does not have the necessary environment variables set up for Android Debug Bridge (ADB) to work. Luckily, this is an easy fix.

There are two ways to set up the environment variables: manually or using a script. We’ll go over both methods below.

Method 1: Manually Set Environment Variables

This method involves setting the environment variables manually in your system settings. The exact steps will vary depending on your operating system, but we’ll give general instructions for Windows and macOS.

Windows:

1. Open the Control Panel and go to System > Advanced system settings.
2. Click the Environment Variables button at the bottom of the window.
3. In the System variables section, click New… and add a variable named ANDROID_HOME with a value of the path to your Android SDK directory (e.g., C:\Users\username\AppData\Local\Android\Sdk).
4. Click OK to save your changes and close all open dialog boxes/windows.
5. Restart any command prompt or terminal windows you have open so that the changes can take effect.
6 Method 2: Use a Script

This method uses a script to automatically set the environment variables for you. It’s a bit more complicated than method 1, but it’s also more flexible.

1. Download the set-adb-env-vars.sh script from here: 2. Copy the script to a directory on your computer. For example, you could create a new directory named “adb” in your home directory and copy the file there.
3. Open a terminal or command prompt window and navigate to the script’s directory (e.g., cd ~/adb).
4. Make the script executable: chmod +x set-adb-env-vars.sh
5. Run the script: ./set-adb-env-vars.sh
6 After running the script, close and reopen any open terminal or command prompt windows so that the environment variable changes can take effect.

2. Solution 2: Check for Conflicting Programs
If you still see the error after setting up your ADB environment variables, it’s possible that another program is using the same port as ADB. To check for this, open a command prompt or terminal window and type netstat -a -n -o | findstr “5037” (without the quotes). This should return a list of all programs using port 5037 on your computer (the default port for ADB). If you see anything other than “LISTENING” next to the ADB program, kill the process using the Task Manager (on Windows) or Activity Monitor (on macOS).

3. Solution 3: Restart ADB
If you’re still seeing the error, try restarting ADB. To do this, open a command prompt or terminal window and type adb kill-server followed by adb start-server. This should restart the ADB service and fix any connection issues.

4. Solution 4: Update ADB
If you’re still seeing the error, it’s possible that your version of ADB is outdated. To update ADB, simply download the latest version from the Android Developer website and replace your existing ADB binary with the new one.

2. Solution 2: Update Android SDK Platform-Tools

If you’re still seeing the “ADB_Vendor_Keys” not set error, try updating your Android SDK Platform-Tools. This is the software that allows your computer to communicate with your Android device.

If you’re getting the “ADB_Vendor_Keys” not set error when trying to use ADB, it’s because your system is missing a critical piece of hardware information. The “ADB_Vendor_Keys” file contains this information, and without it, ADB will not work.

There are two ways to fix this problem: either by manually adding the missing hardware information to the “ADB_Vendor_Keys” file, or by using a tool that will automatically do this for you.

We’ll walk you through both methods so that you can choose the one that’s best for you.

Adding hardware information to “ADB_Vendor_Keys” manually:

1. Open the file in a text editor like Notepad++ or Sublime Text.

2. Find the section labeled “[Hardware]” and add the following lines underneath it:

How do I fix unauthorized ADB?

If you’re getting the “ADB_Vendor_Keys” not set error, it means that your Android Debug Bridge (ADB) is not authorized for debugging on your device. To fix this, you’ll need to add a new line to your adb_keys file with the public key of the computer you’re using for debugging.

To do this, open up a Terminal window and enter the following commands:

cd ~/.android

mkdir adbkeys

cd adbkeys

Now, use your text editor of choice to create a new file called adbkey.pub and paste in the contents of your public key. For example:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDIw6FHu43zKMnVKiWf4vmg5aqyhwRlU/XgSs8xoVOe4Z4ujJCYqgzUXIP0pDJUc7AJgmTNDGmP+LRFBCkBT179qUmYCZP3HfgazD5MgUGWN/yIjoRyt+AO9ThnvOILbuMDjtLGVWQqiCIwbYFTD5sktFhfLRDyEkkFSF0fhX34SxijfdJTYZewEGdCLu table

How do I authorize my ADB device?

If you’re developing Android applications, you need to authorize your development machine in order to access the ADB debugging interface. To do this, you need to add your machine’s public key to the ~/.android/adbkey file on your device.

The easiest way to do this is to use the adb command line tool that comes with the Android SDK:

First, connect your device to your development machine using a USB cable.

Next, open a terminal window and run the following command:

adb devices

You should see a list of all connected devices, including your own. If you don’t see your device listed, make sure that it’s properly connected and that you have enabled USB debugging in the Android Settings menu.

Once you’ve verified that your device is connected, run the following command:

adb keys // Prints all authorized public keys stored on the device

ADB Vendor Keys Error in ADB Sideload

If you’re getting the “ADB_Vendor_Keys” not set error when trying to sideload an update using ADB, it’s most likely because you’re using an outdated version of the Android SDK. To fix this, simply update your Android SDK to the latest version and try again.

If you’re still having trouble, make sure that your ADB vendor keys are properly set. You can do this by running the following command:

adb shell getprop ro.product.vendor.keys

If you see a message saying “not set”, then your keys are not properly set and you’ll need to edit your .bashrc file to add them. Add the following lines to your .bashrc file, substituting in the path to your vendor keys:

export ANDROID_VENDOR_KEYS=/path/to/your/vendor/keys

Once you’ve done that, save and close the file, then run the following command to source it:

source ~/.bashrc

Restart ADB Server

If you’re running into the “ADB_Vendor_Keys” not set error when trying to use ADB, it’s most likely because your ADB server isn’t properly restarted. To fix this, simply restart the ADB server by running the following command:

adb kill-server

adb start-server

Once the server has been restarted, try using ADB again and it should work without any issues.

Revoke USB Debugging

If you’re getting the “ADB_Vendor_Keys” not set error, it means that your Android device’s USB debugging setting has been turned off. To fix this, simply go to your Android device’s Settings menu, then tap on “Developer options.” From there, scroll down until you see the “USB debugging” option and make sure it is enabled.
