This example describes how Android determines the type of network. Share to everyone for your reference, specific as follows:
To determine whether the network type is WiFi, or 3G, or 2G network, different processing of different networks, now will be judged by the method of sorting out for reference
Note: The following data used to move 2G, Unicom 2G, Unicom 3g,wifi I have been tested, the temporary hand

This article has introduced the network state of the judgment, but after testing found that the method can only determine whether WiFi connectivity, and now the smart machine can be WiFi, 3G, or even 2G. So if you don't use the above method, you need to make changes so that it's not connected to the network (WiFi, 3G, 2G). The code is as follows
