Insert data to Realtime Database does not works

Question

I'm trying to create an app if someone want to use my app they must create a user. When they register they will insert first name, last name, phone and email address. After I confirm that the phone is theirs by using Firebase authorization I want to insert his data to a table named Users in my RealTime Database.

When I tried to do it by using this function:

**EDIT: I added the onComplete function but it doesn't execute **

private void storeNewUserData() {
        FirebaseDatabase rootNode = FirebaseDatabase.getInstance();
        DatabaseReference reference = rootNode.getReference("Users");
        User user = new User(phone,firstName,lastName,email);
        reference.setValue(user).addOnCompleteListener(this);
    }


@Override
public void onComplete(@NonNull Task<Void> task) {
    if(task.isSuccessful()){
        Toast.makeText(this, "Inserted User: "+phone+firstName+lastName+email, Toast.LENGTH_SHORT).show();
    }
    else{
        Toast.makeText(this, task.getException().toString(), Toast.LENGTH_SHORT).show();
    }
}

The database has not been updated but the Toast appeared (with all the data).

I don't think there is a problem in my code maybe it's a problem in my Firebase account.. Anyway I add the rules to this database and an image of the table.

Rules

{
  "rules": {
    ".read": "true",
        ".write": "true"
  }
}

build.gradle(app)

    implementation platform('com.google.firebase:firebase-bom:26.8.0')
    implementation 'com.google.firebase:firebase-analytics'

    mAuth.signInWithCredential(credential).addOnSuccessListener(new OnSuccessListener<AuthResult>() {
        @Override
        public void onSuccess(AuthResult authResult) {
            progressDialog.dismiss();
            User user = new User(phone,firstName,lastName,email);
            storeNewUserData();
            Toast.makeText(PhoneAuthActivity.this, "Logged in as "+phone, Toast.LENGTH_SHORT).show();
            startActivity(new Intent(PhoneAuthActivity.this, MainActivity.class));
        }


    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            progressDialog.dismiss();
            Toast.makeText(PhoneAuthActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });
}

You should use a `ValueEventListener` to track changes in a specific node/branch. — Shubham Panchal, Mar 30 '21 at 01:32
Have you tried to attach a complete listener to the setValue() method? Please respond with @AlexMamo — Alex Mamo, Mar 30 '21 at 06:50
@AlexMamo I haven't tried please attach code so I can try it — FridregJohn, Mar 30 '21 at 10:55
@AlexMamo the task is not successfully completed how can I know why? — FridregJohn, Mar 30 '21 at 11:27
Try to log the message that comes when the task is not successful, right? — Alex Mamo, Mar 30 '21 at 11:28
@AlexMamo I just find out that onComplete doesn't execute... — FridregJohn, Mar 30 '21 at 11:52
Which Toast message is displayed? Are you also sure you have an internet connection on the device/emulator? — Alex Mamo, Mar 30 '21 at 12:07
@AlexMamo I used this in my manifest: I get no Toast onComplete doesn't execute — FridregJohn, Mar 30 '21 at 12:11
Most likely, you don't have an internet connection on the device/emulator, right? — Alex Mamo, Mar 30 '21 at 12:12
@AlexMamo I does get the Toast in onSuccess (after storeNewUserData()) — FridregJohn, Mar 30 '21 at 12:14
Internet permissions are not necessary when writing data in Firebase. So most likely you don't have an internet connection (**not** internet permission) on the device. — Alex Mamo, Mar 30 '21 at 12:55
@AlexMamo I tried using my physical device but still no change.. — FridregJohn, Mar 30 '21 at 13:37

I could resolve this issue by changing my device's internet connection network. The app won't work on mobile data, but it worked on the WIFI of some other device.

The reason behind the problem isn't clear yet.
