Android Firebase check connection status?


I have an App with the Firebase Realtime Database. This app should display a ProgressBar if it isn’t connected. How can I do that? I tried it with “.info/connected”, but the results seem pretty random. I need to check the connection to the online database, not the offline database. (basically, i want to disable offline capabilities, and show the user if they are offline)


var firebaseRef = new Firebase('');
firebaseRef.child('.info/connected').on('value', function(connectedSnap) {
  if (connectedSnap.val() === true) 
    /* we're connected! */
  else {
    /* Give a custom Toast / Alert dialogue and exit the application */

You can also add this check

public static boolean isNetworkAvailable(Context con) {
        try {
            ConnectivityManager cm = (ConnectivityManager) con
            NetworkInfo networkInfo = cm.getActiveNetworkInfo();

            if (networkInfo != null && networkInfo.isConnected()) {
                return true;
        } catch (Exception e) {
        return false;

Then check this in your Activity/Fragment

if (isNetworkAvailable)
//Do you task
/*No internet so  Give a custom Toast / Alert dialogue and exit the application */
