Sometimes do Android development need to use the network to connect to the server, if there is no network to prompt. The code is simple and the code is as follows:public static Boolean isnetworkavailable (context context) {Connectivitymanager mgr = (connectivitymanager) Context.getsystemservice (Context.connectivity_service); Networkinfo[] info = mgr.getallnetworkinfo (); if (info! = null) {for (int i = 0;
The magic problem is that after ThinkPad e0000c recovers from the STANDBY state, the wireless network is no longer available. In Windows 7, you can press FN + F8 or F7 to adjust the screen brightness,F9 + FN does not respond either.

Determine the network connection status of the mobile phone
Sometimes Android development requires a network to connect to the server. If there is no network, a prompt is displayed. The code is simple. The Code is as follows:
Public static boolean isNetworkAvailable (Context context) {ConnectivityManager mgr = (Con

Sometimes doing Android development requires a network to connect to the server. Assume that there is no network to prompt. The code is very easy and the code is as follows:public static Boolean isnetworkavailable (context context) {Connectivitymanager mgr = (connectivitymanager) Context.getsystemservice (Context.connectivity_service); Networkinfo[] info = mgr.getallnetworkinfo (); if (info! = null) {for (i
