Notification Every Time Wifi Is Disconnected

I need my application to give a notification whenever WiFi goes offline. I got it to give a notification every time the WiFi connection changes. But I need it to only give a notifi

Solution 1:

use this line in onReceive() of BroadCastReceiver

if(!isNetworkConnectionAvailable(ctx)){
        Toast.makeText(ctx, "Network Connection Available ", Toast.LENGTH_LONG).show();
    }

the code for isNetworkConnectionAvailable() is

publicstaticbooleanisNetworkConnectionAvailable(Context context)
{
    booleanisNetworkConnectionAvailable=false;

    ConnectivityManagerconnectivityManager= (ConnectivityManager)context.getSystemService("connectivity");
    NetworkInfoactiveNetworkInfo= connectivityManager.getActiveNetworkInfo();

    if(activeNetworkInfo != null) 
    {
        isNetworkConnectionAvailable = activeNetworkInfo.getState() == NetworkInfo.State.CONNECTED;
    }
    return isNetworkConnectionAvailable;
}

comment me about result

Solution 2:

Use this to check connectivity InetAddress.isReachable, the method returns true if you have connectivity else false
