Android determines the network status

Android determines the network status. In the Android operating system, how can we correctly determine whether the network we connect is disconnected? Today, we will make a detailed analysis on this application technique.

Public class ConnectionChangeReceiver extends
BroadcastReceiver
{
@ Override
Public void onReceive (Context context, Intent intent)
{
ConnectivityManager connectivityManager =
(ConnectivityManager) context. getSystemService
(Context. CONNECTIVITY_SERVICE );
NetworkInfo activeNetInfo = connectivityManager.
GetActiveNetworkInfo ();
NetworkInfo mobNetInfo = connectivityManager. getNetworkInfo
(ConnectivityManager. TYPE_MOBILE );
If (activeNetInfo! = Null)
{
Toast. makeText (context, "Active Network Type:" +
ActiveNetInfo. getTypeName (), Toast. LENGTH_SHORT). show ();
}
If (mobNetInfo! = Null)
{
Toast. makeText (context, "Mobile Network Type:" +
MobNetInfo. getTypeName (), Toast. LENGTH_SHORT). show ();
}
}
}
