Question

我是Android开发人员的新手。我关注http://developer.android.com/training/basics/firstapp/building-ui.html。当我做简单的hello world应用程序时，第一次应用程序在模拟器上运行。现在我试图运行下一个application.application没有安装在模拟器上，即模拟器没有显示应用程序名称和应用程序图标。然后我从包浏览器中删除了两个应用程序并重新启动了laptop.then我再次进行第二次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min。 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

activity_mail.xml的代码是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">

    android:layout_height="wrap_content"
    android:hint="@string/edit_message"
    />

<Button android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/button_send"/>

 </LinearLayout>

string.xml的代码是

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">My First App</string>
<string name="edit_message">Enter a message</string>
<string name="button_send">Send</string>

安装libGL后，控制台无法显示无法加载libGL.so [2012-12-28 21:23:45 - 仿真器]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 - 仿真器]无法加载libGL.so [2012-12-28 21:23:45 - 仿真器]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仍然应用程序赢了，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"
   android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.second.Second"
        android:label="@string/app_name" android:icon="@drawable/ic_launcher"                android:theme="@style/AppBaseTheme" android:showOnLockScreen="true">

Answer 1

看起来你喜欢在Linux上开发。您需要将一个有效的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。安装适用于i386 / i686架构的Mesa：

模拟器没有安装应用程序
