Learn Android together how to get the network type and determine if it is available (20)

Connectivitymanager main management and network connection related operations , Obtained by Getsystemservice (Context.connectivity_service)

Services that take the network connection. so we can pass Connectivitymanager the getactivenetworkinfo () method under this class to get the current network

connection state, this method returns the Networkinfo Object , Networkinfo describes the current network mobile and WiFi the state. the networkinfo class has

three methods: ( 1 ) GetType () gets the type of the current network, such as Mobileor Wi-Fi . (2)gettypename () Gets the type of the current network

names, such as "WIFI" or "MOBILE". (3) Theisavailable () method is used to determine whether the current network connection is available, returns true, and returns false .

For information on how to view the current network type, see the following code:

Public  String Getnetworkstatename (context context) {    Connectivitymanager Mconnectivitymanager = ( Connectivitymanager) Context.getsystemservice (Context.connectivity_service); Networkinfo mnetworkinfo = Mconnectivitymanager.getactivenetworkinfo (), if (mnetworkinfo.isavailable ()) {//Get network type int Networktype =mnetworkinfo.gettype (); if (Networktype==connectivitymanager.type_wifi) {return "current network is WiFi";} else if (networktype==connectivitymanager.type_mobile) {return "current network is 3G";} else{return "other means";}} Else{return "currently no Network";}        }

Finally, add access permissions in the androidmainfest file:

<uses-permission android:name= "Android.permission.ACCESS_NETWORK_STATE"/>
