adb server version (41) doesn't match this client (40); killing...的解决办法

这个问题的原因是因为你的电脑上已经启动了一个旧版本的 ADB 服务，而你的客户端（比如 Android Studio 或命令行）正在尝试连接到一个新版本的 ADB 服务。为了解决这个问题，你需要执行以下步骤：

1. 首先，在命令行中输入以下命令来停止旧版的 ADB 服务：

adb kill-server

2. 然后，输入以下命令来启动新版的 ADB 服务：

adb start-server

3. 如果你仍然遇到问题，可以尝试在 Android Studio 中选择 "Invalidate Caches / Restart" 选项来清除缓存并重新启动 Android Studio。

希望这些步骤能够解决你的问题。

adb server version (41) doesn't match this client (36); killing...

这个问题是由于 Android Debug Bridge (adb) 服务端和客户端版本不匹配导致的。可以尝试以下解决方法：

1. 确保你的 adb 版本和设备上的 adb 版本一致。
2. 尝试重启 adb 服务，可以使用以下命令：

   adb kill-server
   adb start-server

3. 如果以上方法都无效，可以尝试卸载并重新安装 Android SDK。

adb server version (41) doesn't match this client (39); killing..

This error message indicates that the version of the Android Debug Bridge (ADB) server running on your computer does not match the version of the ADB client you are using. This can happen if you have multiple versions of the Android SDK installed on your computer or if you have updated one component without updating the other.

To resolve this issue, you can try the following steps:

1. Update the ADB client to match the version of the ADB server running on your computer. You can do this by updating your Android SDK or by downloading the latest version of ADB from the Android Developer website.

2. Restart the ADB server by running the following command in a terminal or command prompt:

adb kill-server
adb start-server

3. If the problem persists, try restarting your computer and then starting the ADB server again.

By ensuring that your ADB client and server are running the same version, you should be able to connect to your Android device and debug your applications without any issues.
