fragment

Why Since honeycomb (API level 11), Google has introduced a new set of APIs to help developers build better app, including Fragment and property animation. These new APIs are great, but they are not quite compatible with older devices, thus Google provided a support library to solve this problem. While building my app, I’m trying to use the compat fragment to support as many devices as possible, meanwhile, I want to take advantage of new set of animation apis to create animation easier.
