ContentResolver类有一个名为getSyncStatus(...)的隐藏方法。
为了使其公开可见，我尝试在support {4}的ContentResolverCompat中添加一个包装器方法。
到目前为止，这在Eclipse中有效，但当我调用make时，它失败并出现以下错误：
ERROR: /development/android/frameworks/support/v4/java/android/support/v4/content/SyncStatusInfo.java:91: android.content.SyncStatusInfo cannot be resolved to a type

我的想法只是@hide is a documentation thing，我可以从AOSP课程中访问它。但是，当我想访问隐藏的类/方法时，为什么我无法构建我的更改？
注意：我不想构建Android应用，我想更改/构建Android源代码本身。
修改：这不是@hide class not found的副本，因为@hide意味着它已从JavaDoc中删除，但仍可从Android源代码本身访问。
