  • 0

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,

    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.
