CodePudding user response：

To delete a node from the database you call removeValue() on a DatabaseReference to that node.

So you can create the entire Chats node with:

DatabaseReference root = FirebaseDatabase.getInstance().getReference();
root.child("Chats").removeValue();

To delete a lower-level node, you can specify the entire path to that node:

root.child("Chats/hI151.../messages").removeValue();

You will need to know/specify the entire hI151... value in this code.
