I'll comment only on what I've experienced: Android market will not let you have package version conflicts. It examines the package and if the new version is less than or equal to the old version it will refuse the upload (it did with me).

我只评论我所经历的内容:Android市场不会让你有包版本冲突。它检查包,如果新版本小于或等于旧版本,它将拒绝上传(它与我一起)。

All updates appear as a patch to the user, although I believe they aredownloading a whole new package and not just the changed bytecode.

所有更新都显示为用户的补丁,但我相信他们正在下载一个全新的包,而不仅仅是更改的字节码。
