3、非空注解

一些API上添加了非空注解，如：

• Fragment.getActivity()

• Fragment.getContext()

可能导致Kotlin编译错误

4、fragment 元素共享渐变动画

5、RoundedDrawable 支持XML定义

6、废弃API被移除

如： android.support.v7.NotificationCompat (use v4 NotificationCompat instead)

KeyEventCompat,

ParallelExecutorCompat

SearchViewCompat

Support 27.0.1-27.0.2

Bug fixes

Support

Support 27.1.0

1、DialogFragment的 getDialog 在onDestroyView之前都是非空的（以前通过dismiss置空），可以通过getDialog().isShowing()判断是否显示

2、ListAdapter  、AsyncListDiffer优化RecycyclerView 在后台线程计算List diffs

3、FragmentActivity和Fragment implement ViewModelStoreOwner

4、Fragments 有 requireContext(), requireActivity(), requireHost(), 和 requireFragmentManager() 方法,返回对应非空对象或者 throw anIllegalStateException.

5、findviewbyid的非空实现 requieviewbyid 被加入到windowcompat，activitycompat中，如果找不到对象将抛异常

6、LoaderCallbacks 非空、可空注解优化

7、SortedList.ReplaceAll可以更新sortedlist中的数据，并支持动画
