Android detects network status to determine if the current network is available

The user's current network is available: WiFi, 2g/3g Network, users open and not open the network, and whether can be used is not the same thing. Can use refers to: users open the network and can connect to the Internet for Internet access.

To detect if the current network is available, the code is as follows:

/*** Detect when the network (WLAN, 3g/2g) status *@paramContext Context *@returnTrue indicates that the network is available*/     Public Static Booleanisnetworkavailable (Context context) {Connectivitymanager Connectivity=(Connectivitymanager) context. Getsystemservice (Context.connectivity_service); if(Connectivity! =NULL) {Networkinfo info=Connectivity.getactivenetworkinfo (); if(Info! =NULL&&info.isconnected ()) {                //the current network is connected                if(info.getstate () = =NetworkInfo.State.CONNECTED) {//the network currently connected is available                    return true; }            }        }        return false; }

Permissions added in the Androidmanifest.xml file:

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