Android WiFi Methods

The first thing to emphasize is that WiFi can only be tested on a real machine!

In Android, all WiFi operations are performed in android.net. wiFi bag, And the commonly used classes only use a few. For general developers, the commonly used operations are also limited and do not need to be deliberately remembered, when I use it, I can check it now. The following is an example of WiFi in the secrets of Android Application Development. I personally feel that it is quite complete. I 'd like to share it with you!

I will not explain the detailed description in it. When will it be used? It will be okay when I find it here!
