public class

WifiManager

java.lang.Object

↳

android.net.wifi.WifiManager

This class provides the primary API for managing all aspects of Wi-Fi connectivity. Get an instance of this class by calling [Context.getSystemService(Context.WIFI_SERVICE)](http://api.apkbus.com/reference/android/content/Context.html#getSystemService(java.lang.String)).
It deals with several categories of items:

The list of configured networks. The list can be viewed and updated, and attributes of individual entries can be modified.
The currently active Wi-Fi network, if any. Connectivity can be established or torn down, and dynamic information about the state of the network can be queried.
Results of access point scans, containing enough information to make decisions about what access point to connect to.
It defines the names of various Intent actions that are broadcast upon any sort of change in Wi-Fi state.

This is the API to use when performing Wi-Fi specific operations. To perform operations that pertain to network connectivity at an abstract level, use [ConnectivityManager](http://api.apkbus.com/reference/android/net/ConnectivityManager.html).
