Appium 退回到直接的W3C远程端连接和会话NotCreateDexception:无法创建新的远程会话

运行appium脚本时，会引发异常：

Unable to create new remote session

即使我在appium设置上覆盖了它的会话。 我通过configuration.properties为脚本提供URL和其他参数

…表示AndroidDriver无法启动/生成新的远程会话

您的主要问题是所使用的二进制文件版本之间的不兼容，如下所示：

您使用的是java.version1.8.0_152-release，它非常古老。 解决方案 将JDK升级到最新级别。 重新启动系统。 执行测试。

你的问题的答案在于你所设置的能力

您需要根据自己的能力修改这些行

cap.setCapability(AndroidMobileCapabilityType.APP_PACKAGE,"cfg.getAppPackage()");
cap.setCapability(AndroidMobileCapabilityType.APP_ACTIVITY, "cfg.getAppActivity()");

对,

实际上，您在引号中调用了您的方法，这是不应该做的。直接调用它，就像调用URL和AutomationName一样。

是否有证据表明问题出在Java版本？这听起来像是一个推测性的疑难解答提示，而不是一个有效的答案。您的print语句显示您正试图访问位于的selenium服务器，该服务器不可路由。服务器可能绑定到0.0.0.0，这意味着所有接口。但是您必须使用真正的IP访问它，如127.0.0.1（如果是本地的），或真正的IP（如果是远程的），谢谢您宝贵的时间。通过重新安装io.appium.setting&unlock.apk以及更改功能，问题得以解决。我的情况

cap.setCapability (AndroidMobileCapabilityType.APP_PACKAGE, cfg.getAppPackage());
cap.setCapability (AndroidMobileCapabilityType.APP_ACTIVITY, cfg.getAppActivity());
