谷歌地圖android 2.2 NoClassDefFoundError

Question

我有一個谷歌地圖的問題。當我開始擴展MapActivity的新活動時，我得到了NoClassDefFoundError。我已經建立目標設置爲2.2谷歌API和

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

<application>裏面的定義標籤。我也有mapsApiKey和所有我需要使它的工作，但它不。

     MapView mapView = (MapView) findViewById(R.id.mapview); 
     mapView.setBuiltInZoomControls(true);

}

機器人嘗試把android:name="NewNormalNoteActivity" as this android:name=".NewNormalNoteActivity"

爲

的android：命名

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 Manifest: Why sometimes ".<classname>" instead of just "<classname>"?

Is the activity name in AndroidManifest.xml required to start with a dot?
