android - Retrieving specific data from Firebase Database -

i'm creating chat app on android using firebase database , java. whenever user first registered, stores username database under nodes "user", userid, "profile", "username". username stored using user class. username value stored. when try

mdatabase.child("users").child(userid).child("profile").child("username").tostring(); 

this gives me path username not username itself. know how value of username itself?

edit: gives me error when run

datasnapshot.child("users").child(muserid).child("profile").child("username").getvalue().tostring(); 

here firebase database shows under userid.

you aren't getting value properly. need attach listener child , updates. this:

// reference user final firebasedatabase database = firebasedatabase.getinstance(); databasereference ref = database.getreference("server/path/to/profile");  // attach listener read data @ profile reference ref.addvalueeventlistener(new valueeventlistener() {     @override     public void ondatachange(datasnapshot datasnapshot) {         profile profile = datasnapshot.getvalue(profile.class);         system.out.println(profile.getusername());     }      @override     public void oncancelled(databaseerror databaseerror) {         system.out.println("the read failed: " + databaseerror.getcode());     } }); 

you can find more information , examples on firebase website. keep in mind don't make requests data firebase. attach listeners children , data listener. example assumes have profile model, method username. return profile object , enable whatever data need off of object.
