Appium不会启动

Question

我改变了我的配置，尝试一次运行两个appium会话，这样我就可以检查并在并行端口上运行自动化。不知何故，我打破了监管官的AVD启动。我试图恢复一切，killall会话，停止appium的所有命令行实例，但问题仍然存在。

完整的错误信息：

Answer 1

请检查（打勾）以下选项：

Android Settings -> Basic -> Package [possible cause of failure] 
Android Settings -> Advanced -> SDK 

顺便说一句，这将是刚刚在你想要使用的UI功能（可能使用Appium检查独立）来运行你的应用程序的情况下，否则，如果您正在使用一些client来设置capabilities，很高兴看到您的设置的代码建议任何所需的更改。

Answer 2

缺少应用程序包和活动名称。需要将包和活动名称添加到期望的功能
