Android源引用缺少类 [英] Android source referencing missing classes

问题描述

我克隆了一些来自Android开源项目的树木来看一看在code，但我不能建立他们，因为他们引用这似乎并不存在的类。

有关例如，该音乐应用<一href=\"http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=src/com/android/music/AlbumBrowserActivity.java;h=ba3e2127606f310f61b1f32fe2d01656cd81a57e;hb=master\"相对=nofollow>这里引用 android.media.MediaFile 它根据的包摘要不存在，以及之类的东西 ArrayListCursor 里面有一个老左右，但的javadoc 是的当前文档缺席。

所以，从公布的SDK开源项目脱节？此外，有没有与当前的SDK来构建这些开源软件包的方式？

谢谢，

原来是开源项目脱节
  从发布的SDK？

股票Android应用程序都没有任何关系的SDK。大多数人的SDK存在之前写的。

因此​​，例如，有一个<一个href=\"http://www.google.com/$c$csearch/p?hl=en#uX1GffpyOZk/media/java/android/media/MediaFile.java&q=package%3aandroid%20MediaFile&sa=N&cd=1&ct=rc\"相对=nofollow> android.media.MediaFile 类，和<一个href=\"http://www.google.com/$c$csearch/p?hl=en#uX1GffpyOZk/core/java/com/android/internal/database/ArrayListCursor.java&q=package%3aandroid%20ArrayListCursor&sa=N&cd=1&ct=rc\"相对=nofollow> ArrayListCursor 类。他们不是SDK的一部分，但是你可以快速使用谷歌$找到源为他们C $ C搜索和包：机器人预选赛

  

此外，有没有建立这些办法
  开源软件包与当前
  SDK？

如果通过开源软件包你的意思是应用程序，那么一般不，他们不能使用SDK构建的。有一天，也许他们可以，但不能没有在某些情况下，大量的工作。

I cloned some of the trees from the Android Open Source Project to take a look at the code, but I can't build them because they reference classes which don't seem to exist.

For instance, the music application here references android.media.MediaFile which according to the package summary does not exist, as well as things like ArrayListCursor which has an old javadoc around but is absent in current documentation.

So is the open source project disjoint from the released SDK? Also, is there a way to build these open source packages with the current SDK?

Thanks,

解决方案

So is the open source project disjoint from the released SDK?

The stock Android applications have nothing whatsoever to do with the SDK. Most were written before the SDK existed.

So, for example, there is an android.media.MediaFile class, and an ArrayListCursor class. They are not part of the SDK, but you can find the source for them quickly using Google Code Search and the package:android qualifier.

Also, is there a way to build these open source packages with the current SDK?

If by "open source packages" you mean applications, then generally no, they cannot be built using the SDK. Someday, perhaps they can be, but not without substantial work in some cases.
