Can anyone tell me what I am doing wrong. Thank you in advance

Answer 1

once user model gets filled by the profile details (feilds)

Map<String, Object> childUpdates = new HashMap<>();

myRef = database.getReference("parent_node**strong text**name").child(user_profile_id);

myRef.child(user_profile_id).push();

childUpdates.put(user_profile_id, usermodel);

myRef.updateChildren(childUpdates);

The above code generates parent node with user id and the user model gets saved as a value for that id(ie user id) , you may later fetch those profile details by calling userid as a key in the Firebase Database

Hope it helps :)

Answer 2

Place all the values you want in a hashMap and save all of them together by using the setValue function.

Also, if there is by chance a small problem with your mref, try declaring it like this.

mref = FirebaseDatabase.getInstance().getReference();

I hope this helps
