Updating the data on Firebase Android

In Firebase To update specific value you can use it...

ref.child("myDb").child("awais@gmailcom").child("leftSpace").setValue("YourDateHere");

or you can move into child using "/" as follow :

ref.child("myDb/awais@gmailcom/leftSpace").setValue("YourDateHere");

you can assign new value in same child,like

  Firebase firebase = new Firebase("your database link/myDb");
    firebase.child("[email protected]").child("leftSpace").setValue("newValue");
