请问2.3新增的CNE模块是做什么用的?
1. 在ConnectivityService.java同级目录下多了一个CNE.java;2. 在ConnectivityService初始化时，也初始化了Cne
3. 在log中大量看到Cne的信息.
4. 在ConnectivityService的处理中，多出用到了Cne相关的条件判断。
请问有大牛知道，2.3新增的CNE是个什么功能模块吗？
能给详细的解释解释吗？
十分感谢！

求解释 --------------------编程问答-------------------- 我下的2.3的源码,没找到cne.java...可能是版本低了点... --------------------编程问答-------------------- 你用的是Qualcomm的平台吧，这是Qualcomm加的东西，不是google的；
CNE = Connectivity Engine

我在android代码里也看到了这个类。原来是高通的啊。
补充：移动开发 , Android
