android - 从Marketplace下载带有两个Launcher组件的应用程序后，点击 "Open"会导致崩溃

Question

创建一个带有两个启动器图标的示例应用程序。例如，两个 组件如:

<application ...> 
  <activity ... android:name="TestActivity01"> 
    <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 
  </activity> 
  <activity ... android:name="TestActivity02"> 
    <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 
  </activity> 
</application> 

通过从 Marketplace 下载安装应用程序，或通过 应用程序安装程序。当消息框询问您是否要运行 应用程序，抛出异常:

崩溃的发生是因为 com.android.internal.app.ResolverActivity 是 试图找到解决以下 Intent 的(单个)组件:

  <action android:name="android.intent.action.MAIN" /> 
  <category android:name="android.intent.category.LAUNCHER" /> 

请注意，这已经通过 AppInstaller 和 真实设备上的真实市场。

Mike 的解决方案对我有用:

请注意， Activity 别名标签必须在您引用的 Activity 标签之后声明(在 xml 中)。

参见 http://code.google.com/p/android/issues/detail?id=6579

要获得适当的解决方法，请将此 Activity 别名添加到您的 list 中:

<activity-alias android:name="com.android.internal.app.ResolverActivity"
                android:targetActivity=".Main" android:exported="true">

将 .Main 替换为您要在启动时作为默认值启动的 .ClassName 在这种情况下点击打开按钮
