In official android.jar library i've not Fragment and FragmentList classes

In official开发者_运维技巧 android.jar library i've not Fragment and FragmentList classes, where i can find them? Thank u very much, guys!

To include fragments in your projects you need to add the compatibility package jar for your project which is a library of api's that was developed for honeycomb. If should be in your sdk folder, for eg in path like

E:\Softwares\Android\android-compatibility\v4\android-support-v4.jar

In Compatibility package, or in later android SDK (3.0 and higher).
