Use this code to check connectivity:

final ConnectivityManager conMgr =  (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
final NetworkInfo activeNetwork = conMgr.getActiveNetworkInfo();
if (activeNetwork != null && activeNetwork.isConnected()) {
    //being here means you are connected
} else {
    //being here means you are not connected
} 

And also include this in your manifest:

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

So you can set a boolean to true or false depending on connectivity and use it to determine if you should open the menu or not.
