Android - How to check internet Access, not just connectivity to wifi? [duplicate]

Answer 1

Actually I used the same function isInternetOn() but I removed the connecting condition. It had to check the status of connection if connected or not and if it is trying to connect. This didn't work for me, so I removed connecting status checking and then it worked.

Thanks for all replies.

public final boolean isInternetOn()
{
  ConnectivityManager connec = (ConnectivityManager)
    getSystemService(Context.CONNECTIVITY_SERVICE);

  // ARE WE CONNECTED TO THE NET
  if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED ||
       connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED )
  {
    // MESSAGE TO SCREEN FOR TESTING (IF REQ)
    //Toast.makeText(this, connectionType + ” connected”, Toast.LENGTH_SHORT).show();
    return true;
  }
  else if ( connec.getNetworkInfo(0).getState() == NetworkInfo.State.DISCONNECTED
    ||  connec.getNetworkInfo(1).getState() == NetworkInfo.State.DISCONNECTED  )
  {
    return false;
  }

  return false;
}

You can use BroadcastReceivers that will trigger when the connection status change: there is a similar question with an answer: Broadcast intents for bluetooth, wifi and ringer mode

Answer 3

see the sample:

public static boolean isWifiEnabled() {
    if ( !gWifiManager.isWifiEnabled()) {

        if (mCanShowWifiToast) {
            new Thread(mWifiToastControl).start();
            G.gHandler.post(mNoWifiRunnable);
        }

        return false;
    } else {
        int linkspeed = gWifiManager.getConnectionInfo().getLinkSpeed();
        if (linkspeed < 5) {
            if (mCanShowWifiToast) {
                new Thread(mWifiToastControl).start();
                G.gHandler.post(mNoWifiRunnable);
            }

            return false;
        }
    }

    return true;
}
