包com.google.android.maps解决不了

Question

我想要导入这些包 import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; 我mainactivity.java

但是Eclipse不能解决这些包，我不知道这样做的原因。

我按照电子书上的说明逐步了解了如何在应用中导入地图，并且没有提及此错误。

这里是我的文件：

右键单击您的项目--->属性---> android->选择目标名称Google ApIs。并清理项目并构建项目。

Answer 2

在你的eclipse项目中，检查你使用的是谷歌-15而不是平台的android-15，地图支持只能作为谷歌附加包中的一个额外的lib。
