that class very simple, the Activity, Fragment, Fragment of abstract methods v4 packet just under unified, convenient package BaseActivity, BaseFragment, BaseFragmentV4. For example contentViewLayoutId method is to allow developers to directly back id layout, but do not have to write code to load the layout.

Do not look at this class has 200 lines, in fact, most of the code is overloaded, in order to meet the needs of Unity end, the real way to pay attention to it so three or four, only generateIOnUnity3DCallDelegate (@NonNull UnityPlayer unityPlayer , @ Nullable bundle bundle) inherited this method requires implementers to focus on the role of this method is to generate a real end to load and display Unity view of the module, you are not off view Ye Hao, Fragment, but whatever you realized IOnUnity3DCall IUnityPlayerContainer interfaces and interfaces, you can load and view end Unity display.
By default, the class is inherited UnityPlayerActivity to load and display module Unity end view, unless you override generateIOnUnity3DCallDelegate (@NonNull UnityPlayer unityPlayer, @ Nullable Bundle bundle) method that returns the appropriate agent, this can be from initUnityPlayer (@NonNull Bundle the bundle) method intuitive see inside.
If you want to go further, to achieve the agent module IOnUnity3DCall interface and the interface IUnityPlayerContainer also want to show the other modules Unity short View, then realized the agent module IOnUnity3DCall IUnityPlayerContainer interfaces and interfaces can be achieved in IGetUnity3DCall interface rewrite generateIOnUnity3DCallDelegate (@NonNull unityPlayer unityPlayer, @ Nullable Bundle bundle) method returns the appropriate agent. Of course, in most cases we may not need to do it.
Based on the above principle, let Fragment method as a display module Unity short View of almost certain of:

achieved both exactly the same, just to make developers less a package for a Fragment. I think that when you see here, the method of how to make a heart or ViewGroup Dialog displayed View Unity side has been very clear it.
