This report details the changes in the core Android framework API between two API Level specifications. It shows additions, modifications, and removals for packages, classes, methods, and fields. The report also includes general statistics that characterize the extent and type of the differences.
This report is based a comparison of the Android API specifications whose API Level identifiers are given in the upper-right corner of this page. It compares a newer "to" API to an older "from" API, noting all changes relative to the older API. So, for example, API elements marked as removed are no longer present in the "to" API specification.
To navigate the report, use the "Select a Diffs Index" and "Filter the Index" controls on the left. The report uses text formatting to indicate interface names, links to reference documentation
, and links to change description. The statistics are accessible from the "Statistics" link in the upper-right corner.
For more information about the Android framework API and SDK, see the Android Developers site.
这篇报道详述了Android框架核心API在两个版本之间的更新。下面罗列了包、类、方法、变量的新增、修改和删除。该报道还包括了一般的统计特征的程度和类型的差异。
这篇报道基于Android API规格书的对比，在页面的右上角已经给出了。To代表新的API，From代表旧的API。注意所有相对旧API的变化。比如，API元素被标记为已删除那这个API就不会出现在To（新API）规格文档中了。
可以使用页面左边的“选择变化的索引”和“过滤索引”来导航当前文档。报道使用文本格式标记接口名称，查看：links to reference documentation , 和 links to change description。统计数据可以在右上角的“统计”连接中查看。
