how to use service to detect network status in android
<p>I am using <code>BroadCastReceiver</code> to monitor network status on a activity. But it's not working out. Could anyone please help me.</p>

<pre><code>import android.app.ListActivity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.widget.Toast;

public class GTChat extends ListActivity {

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

    }

    // /////////////////////////////////////////////////////////////////

    private BroadcastReceiver mConnReceiver = new BroadcastReceiver()

    {

        @Override
        public void onReceive(Context context, Intent intent)

        {

            NetworkInfo info = (NetworkInfo) intent
                    .getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);

            if (info.getState().equals(NetworkInfo.State.CONNECTED))

            {

                GTalkChatDetails.chat(getApplicationContext());
                GTalkChatDetails.adddMsgListener(getApplicationContext());

            }

            else

            {

                Toast.makeText(getApplicationContext(),
                        "Network not connected", Toast.LENGTH_LONG).show();

            }

        }

    };

    // //////////////////////////////////////////////////

    protected void onPause()

    {

        unregisterReceiver(mNetworkReceiver);

        super.onPause();

    }

    protected void onResume()

    {

        registerReceiver(mNetworkReceiver, new IntentFilter(
                ConnectivityManager.CONNECTIVITY_ACTION));

        super.onResume();

    }
}
</code></pre>
