How can I get the Key from my Firebase Database

Question

I want to get the id from Firebase, I am build android app using Java

You'll need to be keeping the key you need in the `Upload` class in order to be able to look it up in your click listener. — Frank van Puffelen, Aug 09 '20 at 15:03

Putting suggestion by Sir Frank van Puffelen in action -

You can get key value from documentSnapShot -

@Override
public void onDataChange(@NonNull DataSnapshot snapshot) {
    String docuementKey = documentSnapshot.getReference().getId();

    //toast message 
    Toast.makeText(getApplicationContext(), docuementKey, Toast.LENGTH_SHORT).show();
}

then you can save it in your Upload POJO.

Happy Coding !

thanks for the answer Nikhil Sharma but the issue is I need to get key from database not on Firestore :( – Kneelon Aug 09 '20 at 23:15
`Toast.makeText(getApplicationContext(), docuementKey, Toast.LENGTH_SHORT).show()` will give you the key value you have marked red on your question image, and if Firebase Firestore is not your database then which database you are referring to ? – Nikhil Sharma Aug 10 '20 at 02:56
I want to get the key from My Firebase Database, not from Firestore, yes my companyName and imageUrl is from Firestore, but I need to get the KEY from FIREBASE DATABASE, thanks for your Response Nikhil Sharma I really appreciate it, Thank you, Still waiting for the response Sir Nikhil – Kneelon Aug 10 '20 at 06:41
could you post a screen shot distinguishing FIREBASE DATABASE KEY and FIRESTORE KEY, according to your understanding of both and are you referring to [Realtime Database](https://firebase.google.com/docs/database/rtdb-vs-firestore) – Nikhil Sharma Aug 10 '20 at 06:57
Yes I'm referring to Firebase Realtime database. thank you Nikhil, thumbs up to you, I need to get the key of my Realtime database – Kneelon Aug 10 '20 at 10:24
`FirebaseDatabase.getInstance().getReference("your_document_path").getId()` .. have you try that ? – Nikhil Sharma Aug 10 '20 at 10:31
