环境详情如下：
- 该应用程序是使用Corodova ionic
开发的- Appium版本1.4.16.1
- Android版本6（牛轧糖）
由于这个问题，我的工作完全被阻止了。任何人都可以帮助我摆脱这个问题。如果需要更多信息，请退回。

答案 0 :(得分：0)
你的问题在stacktrace中非常明显：
unknown error: Device b133582d is not online
这意味着您的设备无法使用。
adb devices命令
offline 顺便说一下，还有几个要解决的问题：
答案 1 :(得分：0)
无需使用driver.context(setContext);
对于Android OS 6.0及更高版本，新的UIAutomator具有识别webView元素的内置功能。确保您已更新设备中的 Android System WebView ，如果未更新，则可以通过PlayStore进行更新。
此外，您应该拥有最新版本的Android SDK包。如果没有，那么您也可以使用Android SDK Manager更新它。
使用上述配置，您的问题应该得到解决。如果没有解决，那么您应该尝试以下选项：
要查看混合中UIAutomator Developer内的WebView，请启用＆＃34; setWebContentsDebuggingEnabled ＆＃34;在您的应用的Android源代码中。
如何检查应用的setWebCOntentDebuggingEnabled是否设置为true：
1.将设备连接到机器。 2.打开具有WebView的应用程序屏幕。 3.在机器上打开Chrome浏览器。 4.输入＆＃34; chrome：// devices /＆＃34;在Chrome浏览器地址栏中输入。
如果您在列表中看到您的设备并且要查看该选项，则会为您的应用启用webView调试。如果不可见则不启用。
