I have a number of child nodes in my firebase db and I want to delete only one child node.
Firebase firebase=new Firebase("..address..");
firebase.push().setValue(classObj);
//here classObj is a class object which has a getter and setter for an integer id
Now that I have pushed multiple objects I want to delete only one based on the id in the classObj
To remove data:
firebase.child(id).removeValue();
You might do well to have a look at the Firebase documentation for Android btw, which covers this and many more topics.
