firebase How to get push key value from Firebase Database? Android Example
Example
Let's assume we have a Dogs application, then our model will be a Dog class.
DatabaseReference reference = FirebaseDatabase.getInstance().getReference().child("dogs");
This is how to send a Dog to the database, a new unique dog and set the dog with the key.
String key = reference.push().getKey();
Dog dog = new Dog("Spike");
dog.setKey(key);
reference.child(key).setValue(dog);
The reference.child(key).setValue(dog); is equivalent of reference.push().setValue(dog); And add the benefit of getting the key inside the Dog object.
