我是 android 开发人员的新手。我正在关注http://developer.android.com/training/basics/firstapp/building-ui.html。当我第一次在模拟器上运行简单的 hello world 应用程序时。现在我正在尝试运行下一个应用程序。应用程序未安装在模拟器上，即模拟器没有显示应用程序名称和应用程序图标。然后我从包资源管理器中删除了两个应用程序并重新启动笔记本电脑。然后我再次创建第二个应用程序并尝试安装在 emulator.Emulator 上再次没有显示应用程序。然后我尝试在模拟器上安装 hello world 应用程序，这也不起作用。我检查了最小值。android manifest.xml 中的 sdk 版本和目标 sdk 版本都是正确的。Hello 是第二个应用程序的项目名称。
控制台正在显示

安装 libGL.so 后控制台不显示 Failed to load libGL.so [2012-12-28 21:23:45 - Emulator] 错误 libGL.so：无法打开共享对象文件：没有这样的文件或目录 [2012-12 -28 21:23:45 - Emulator] Failed to load libGL.so [2012-12-28 21:23:45 - Emulator] error libGL.so: cannot open shared object file: No such file or directory but still application won ,t 安装在模拟器上。
这是 hello 应用程序的 androidmanifest.xml 文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.second"
