android uiautomator导致“很遗憾，设置已停止”错误
提问于 2013-10-23 13:57:21
getUiDevice().pressHome();
new UiObject(new UiSelector().description("Apps")).click();
new UiObject(new UiSelector().text("Apps")).click();
new UiScrollable(new UiSelector().scrollable(true)).setAsHorizontalList().scrollIntoView(new UiSelector().text("Settings"));
new UiObject(new UiSelector().text("Settings")).click();
new UiScrollable(new UiSelector().scrollable(true)).scrollTextIntoView("Accessibility");
new UiObject(new UiSelector().text("Accessibility")).click();最后一行代码在我的Nexus4上导致了以下错误，我试着谷歌了一下，但找不到任何相关的信息，所以有人能帮助解释为什么会发生这个错误吗？

这应该是个简单的解决方法。当您在应用程序中导航时(例如，加载应用程序或新页面，或任何需要加载的内容)，而不是使用
new UiObject(new UiSelector().description("Apps")).click();
new UiObject(new UiSelector().text("Apps")).click(); 尝试使用
new UiObject(new UiSelector().description("Apps")).clickAndWaitForWindow();
new UiObject(new UiSelector().text("Apps")).clickAndWaitForWindow(); 页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
