 nInfo.getActiveNetworkInfo().isConnectedOrConnecting();
 Log.i(TAG, "Net avail:"
 + nInfo.getActiveNetworkInfo().isConnectedOrConnecting());
 ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
 NetworkInfo netInfo = cm.getActiveNetworkInfo();
 if (netInfo != null && netInfo.isConnectedOrConnecting()) {
 Log.i(TAG, "Network is available");
 return true;
 } else {
