这个错误表明在Appium配置中缺少必需的deviceName参数。虽然你的配置中已经包含了appium:deviceName，但可能由于格式问题未被正确识别。以下是解决方案：

正确的Desired Capabilities配置

{
  "platformName": "Android",
  "deviceName": "2MN0224907000001",
  "platformVersion": "23",
  "appPackage": "com.leiting.xian",
  "appActivity": "com.gbits.hook.HookUnityPlayerActivity"
}

或者使用带命名空间的格式（Appium 2.0+推荐）：

{
  "platformName": "Android",
  "appium:deviceName": "2MN0224907000001",
  "appium:platformVersion": "23",
  "appium:appPackage": "com.leiting.xian",
  "appium:appActivity": "com.gbits.hook.HookUnityPlayerActivity"
}

常见问题排查

1. Appium版本兼容性：

   • 如果你使用的是Appium 1.x，请使用第一种格式（无命名空间）
   • 如果是Appium 2.x，两种格式都应该支持

2. adb设备验证：
   确保设备已连接且被识别：

   adb devices
   

   应该能看到你的设备ID 2MN0224907000001

3. 完整Java代码示例（如果你是用Java客户端）：

   DesiredCapabilities caps = new DesiredCapabilities();
   caps.setCapability("platformName", "Android");
   caps.setCapability("deviceName", "2MN0224907000001");
   caps.setCapability("platformVersion", "23");
   caps.setCapability("appPackage", "com.leiting.xian");
   caps.setCapability("appActivity", "com.gbits.hook.HookUnityPlayerActivity");
   

如果问题仍然存在，建议：

1. 检查Appium服务器日志获取更详细的错误信息
2. 尝试使用Appium Desktop客户端验证你的capabilities
3. 确保设备USB调试已开启且已授权电脑连接
