Android-determine the network status

Android mobile phones support both WIFI and 3G, determine the network connection, and determine the network type (WIFI or 3G ).

Permission:

Determine network connection

/*** Determine whether the Network is available. This method is used to check network requests in advance to save resources. ** @ return available status */public static boolean isNetAvailable () {Context context = App. getAppContext (); ConnectivityManager manager = (ConnectivityManager) context. getSystemService (Context. CONNECTIVITY_SERVICE); NetworkInfo = manager. getActiveNetworkInfo (); return (info! = Null & info. isAvailable () & info. isConnected ());}

Determine the network type

ConnectivityManager conMan = (ConnectivityManager)     context.getSystemService(Context.CONNECTIVITY_SERVICE);// 3GState mobile = conMan.getNetworkInfo(0).getState();// WIFIState wifi = conMan.getNetworkInfo(1).getState();if (mobile == NetworkInfo.State.CONNECTED     || mobile == NetworkInfo.State.CONNECTING) {    // TODO: in mobile do something} else if (wifi == NetworkInfo.State.CONNECTED             || wifi == NetworkInfo.State.CONNECTING) {    // TODO: in wifi do something}
