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.
這篇報(bào)道詳述了Android框架核心API在兩個(gè)版本之間的更新。下面羅列了包、類、方法、變量的新增、修改和刪除。該報(bào)道還包括了一般的統(tǒng)計(jì)特征的程度和類型的差異。
這篇報(bào)道基于Android API規(guī)格書的對(duì)比，在頁面的右上角已經(jīng)給出了。To代表新的API，F(xiàn)rom代表舊的API。注意所有相對(duì)舊API的變化。比如，API元素被標(biāo)記為已刪除那這個(gè)API就不會(huì)出現(xiàn)在To（新API）規(guī)格文檔中了。
可以使用頁面左邊的“選擇變化的索引”和“過濾索引”來導(dǎo)航當(dāng)前文檔。報(bào)道使用文本格式標(biāo)記接口名稱，查看：links to reference documentation , 和 links to change description。統(tǒng)計(jì)數(shù)據(jù)可以在右上角的“統(tǒng)計(jì)”連接中查看。
