我在测试包含google maps API的Android应用程序时遇到了一些麻烦。正式的API示例工作得很好，但如果我将代码复制到我自己的项目中，它会一直说：“应用程序意外停止”。我多次查看密钥库中的密钥并在谷歌上注册。甚至尝试重新安装SDK。有人知道问题是什么吗？Google Maps Api android key
在此先感谢

基本上我的代码是：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//connect to server
//get current map scope
//get media within map scope + a bit
//init and show map
setContentView(R.layout.main);
//add zoom controls
mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
//add menu
}

XML文件第6行是：
<com.google.android.maps.MapView android:id="@+id/mapview" ...
其后是其他的XML参数行
能否请您发表以下异常和一些代码？ 这个问题一定是别的，一个错误的API键不会导致强制关闭对话框，它只是显示一个空白的网格而不是地图。 – 2010-05-16 12:49:50
