我有两个库（.so），我在java代码中加载。如何使用本机活动？它可以与传统活动结合吗？
但是有几个具体的操作需要Java（Activity）< - > C++（.so files）调用。
我可以使用Native Activity来实现这些功能的一部分吗？本土活动是传统活动的补充或我必须选择哪种类型的活动？

有一组事件可以在本机代码由native activity

因为我知道我的部分代码（应该在特定事件后调用）是用C++编写的，我认为它会更好通过本地活动在C++中处理。不过，我也有代码必须在Java中的句柄事件后调用。
问题是...我可以有我的活动的本地版本（本机界面），这将有助于我的一些事件，并在这同一时间的同一活动的传统java界面？
据我了解@noisy你的问题是，“你无法加载两个本地库”我是否正确？ – 100rabh 2011-03-21 09:59:09
