try this one to check internet connection availability

public boolean isNetworkAvailable(Context context) {
ConnectivityManager connectivity =   (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null) {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null)
    for (int i = 0; i < info.length; i++)
        if (info[i].getState() == NetworkInfo.State.CONNECTED) {
            return true;
        }
    }
    return false;
}

Use this one to check every 40 sec

Timer  networkTimer = new Timer();
NetWorkTimerTask networkTimerTask = new NetWorkTimerTask();
networkTimer.schedule(networkTimerTask, 0,40*1000);
public class NetWorkTimerTask extends TimerTask {

    @Override
    public void run() {
        networkHandler.sendEmptyMessage(0);
    }
}; 
@SuppressLint("HandlerLeak")
Handler networkHandler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        isOnline = isNetworkAvailable(getApplicationContext());
    }
};

Add permission in AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

I make some changes, try it. – Ramki Anba Jun 02 '14 at 09:32 — Ramki Anba, Jun 02 '14 at 09:32

public boolean isOnline() {
    ConnectivityManager cm =
        (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo netInfo = cm.getActiveNetworkInfo();
    if (netInfo != null && netInfo.isConnectedOrConnecting()) {
        return true;
    }
    return false;
}

and add this

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

public boolean isOnline() {
        ConnectivityManager conMgr = (ConnectivityManager) getApplicationContext()
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = conMgr.getActiveNetworkInfo();

        if (netInfo == null || !netInfo.isConnected() || !netInfo.isAvailable()) {
            /*
             * Toast.makeText(getActivity(), "No Internet connection!",
             * Toast.LENGTH_LONG).show();
             */
            return false;
        }
        return true;
    }

and Call it like

if (isOnline()) {
//code if net available
}
else
{
Toast.makeText(MainActivity.this,"No Internet connection available  ",
                            Toast.LENGTH_SHORT).show();
}

And if you want to check on Interval then put if condition in thread
