模拟器没有安装应用程序

Question

我是安卓开发者的新手。我关注http://developer.android.com/training/basics/firstapp/building-ui.html。当我第一次制作简单的 hello world 应用程序时，应用程序在模拟器上运行。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这两个应用程序并重新启动笔记本电脑。然后我再次制作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 无法加载 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 - 模拟器] 无法加载 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 但应用程序仍然无法安装在模拟器上。

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"
  android:versionCode="1"

Answer 1

看起来您正在 Linux 上进行开发。您需要将一个工作 libGL.so 符号链接到您的 32 位 lib 目录中。这可以像“sudo ln -s /usr/lib/libGL.so.1 /usr/lib/libGL.so”一样简单。

Answer 2

libGL.so 属于 Mesa libGL 运行时库。模拟器抱怨，因为它找不到 32 位 Mesa 库。为 i386 / i686 架构安装 Mesa：
