Adding Firestore document doesn't Fail or Succeed

I am trying to add documents to Firebase Firestore from my android app. This is the code that I currently have.

FirebaseFirestore db = FirebaseFirestore.getInstance();


Map<String, Object> newuser = new HashMap<>();
        newuser.put("Username",username);
        newuser.put("Password",password);
        newuser.put("Nickname",userNickname);
        newuser.put("Code", "ffff");
        newuser.put( "Othercode", "ffffffff");
        newuser.put("Age", "0");
        
        //Point 1

        db.collection("Users").document(username).set(newuser)
                .addOnSuccessListener(new OnSuccessListener<Void>() {
                    @Override
                    public void onSuccess(Void aVoid) {
                        //Point 2
                    }
                })

                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        //Point 3
                    }
                });
//Point 4

When I run this code it will reach Point 1 and Point 4, but never Point 3 or Point 2. I'm pretty new to android and java so I'm not sure what the things in the Logcat mean either:

It was functioning, but suddenly it stopped working, so I'm not sure what I did. If you need any more code, I can provide it as well. Thank you in advance!

You probably need to Wipe Data from the current AVD you are using and try running it agian.

I think that the AVD Internet wasn't working correctly, or too much was running on it so when I wiped the data this was solved. I don't think that this can happen on a real device, but I'm not sure. Hopefully this is works for anyone else with this issue.

I had the same problem and for me it was the emulator. I've downgraded it to v31.2.10 and all the attempts when the inserts didn't work to the Firestore completed after the downgrade.

You can get older emulator versions from https://developer.android.com/studio/emulator_archive
