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 = (ConnectivityManager) context. getSystemService (Context. CONNECTIVITY_SERVICE); NetworkInfo [] info = mgr. getAllNetworkInfo (); if (info! = Null) {for (int I = 0; I <info. length; I ++) {if (info [I]. getState () = NetworkInfo. state. CONNECTED) {return true ;}} return false ;}

You can directly reference it when using it, as shown in figure

IsNetworkAvailable (MainActivity. this );
