Answer 1

in the android developer guide mentioned you can Monitor for Changes in Connectivity

1st - you create a NetworkChangeReceiver class that is a BroadCastReceive , where you implement your code to download what you want :

public class NetworkChangeReceiver extends BroadcastReceiver {

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

    final ConnectivityManager connMgr = (ConnectivityManager) context
            .getSystemService(Context.CONNECTIVITY_SERVICE);

    final NetworkInfo wifi = connMgr
            .getNetworkInfo(ConnectivityManager.TYPE_WIFI);

    NetworkInfo activeNetwork = connMgr.getActiveNetworkInfo(); 

    boolean isConnected = wifi != null &&   
                wifi.isConnected() ;

    if (isConnected ) {
        // Do something

        Log.d("Netowk Available ", "Flag No 1");
    }
  }
}

2nd - you register your BroadCastReceiver in the manifest file like the following :
