Question

    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();

最后一行代码导致我的Nexus 4出现以下错误，我试图谷歌，但无法找到任何相关信息，那么任何人都可以帮助解释错误发生的原因吗？

应该是一个简单的解决方案。当您浏览应用程序时（即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();
