android - com.example.android.apis.R 在哪里？

Question

所以我正在尝试完成这里的示例:

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/SurfaceViewOverlay.html

在导入的最后一行，它说

//Need the following import to get access to the app resources, since this
//class is in a sub-package.
import com.example.android.apis.R;

问题是我从哪里得到包含这个的包？我在网上发现的信息很少，而且显然还没有，因为在我输入时它带有红色下划线。我知道这可能是一个新手问题，但嘿，我们都从某个地方开始......
