我有谷歌地图的问题。当我开始扩展 MapActivity 的新活动时，我收到 NoClassDefFoundError。我已使用 google api 将构建目标设置为 2.2，并且

<uses-library android:name="com.google.android.maps" />

<application>标签内的定义。我也有 mapsApiKey ，我需要让它工作，但它没有。

android尝试放 android:name="NewNormalNoteActivity" as this android:name=".NewNormalNoteActivity"

作为

机器人：名称

The name of the class that implements the activity, a subclass of Activity. 
The attribute value should be a fully qualified class name (such as, "com.example.project.ExtracurricularActivity").
 However, as a shorthand, if the first character of the name is a period (for example, ".ExtracurricularActivity"), 
 it is appended to the package name specified in the <manifest> element.

Android 清单：为什么有时是“.<classname>” 而不仅仅是“<classname>”？

AndroidManifest.xml 中的活动名称是否需要以点开头？
