机器人 - 支持旧设备（姜饼）

Question

更新谷歌地图API的Android V2：

在我的Android SDK管理器，我已经安装了Android支持库。在我的Downloads/android-sdk-macosx/extras/android/support目录中，我有一个v4，v7和v13。我将android-support-v4.jar复制到libs文件夹。右键单击并选择“构建路径”>“配置构建路径”。在活动布局添加以下（使用supportmapfragment而不是mapfragment）：

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.SupportMapFragment"/> 

但我仍然得到这个错误：

04-16 17:42:00.928: E/AndroidRuntime(363): FATAL EXCEPTION: main 
04-16 17:42:00.928: E/AndroidRuntime(363):

inflating class fragment 

下面是完整的跟踪：

任何想法？

Answer 1

仅在API级别12后才支持MapFragment。建议使用SupportMapFragment代替。

要使用此功能，您需要将Android支持库添加到您的路径中。按照这些instructions将支持库添加到您的项目。

UPDATE：

此外，Fragment类不可用，直到API等级11，我相信你的目标姜饼这是API等级10。这就是为什么你越来越以下错误：

Caused by: java.lang.ClassNotFoundException: android.view.fragment in loader dalvik.system.PathClassLoader

看到这个Question，它看起来是一个类似的问题。
