I cannot seem to connect to Firestore database to save user's data-CodePudding

I'm currently working on an Android project and I've been stuck with this problem for a few hours now.

I'm trying to connect to my Firestore database. The idea is to store documents with additional info from the users. It's created on-register and then sent to the database.

Here's the code:

    auth.createUserWithEmailAndPassword(email, password)
        .addOnCompleteListener(this) { task ->
            if (task.isSuccessful) {
                // Sign in success
                Log.d("RegistroFirebase", "createUserWithEmail:success")
                val user = auth.currentUser

                // Create user's database document

                writeNewUser(
                    user!!.uid, user!!.email, binding.signUpName.text.toString(),
                    binding.signUpSurname.text.toString(), "623623623")
                    Log.d("Crear documento usuario", "Success?")

                reload("main")`

And the function:

private fun writeNewUser(userId: String, email: String?, name: String, surname: String, phone:String) {
    val user = User(email, name, surname, phone)

    db.child("users").child(userId).setValue(user)
}

Also I have a class for users:

data class User(val email:String? = null, val name:String? = null,
                val surname:String? = null, val phone:String? = null) {}

As for the error, I this single line from the logcat.

2021-11-16 13:56:25.826 12534-12665/com.example.senato W/PersistentConnection: pc_0 - Firebase Database connection was forcefully killed by the server. Will not attempt to reconnect. Reason: Firebase error. Please ensure that you spelled the name of your Firebase correctly

Any help would be appreciated. Thank you in advance

CodePudding user response：

You say:

I cannot seem to connect to Firestore database to save user's data

And it makes sense, since when using the following lines of code:

val user = User(email, name, surname, phone)
db.child("users").child(userId).setValue(user)

You are trying to write data to the Realtime Database and not to Cloud Firestore. While both, databases are a part of Firebase services, they are different databases with different mechanisms. To be able to write data to Firestore, please use the following line of code:

FirebaseFirestore db = FirebaseFirestore.getInstance();
CollectionReference usersRef = db.collection("users");
usersRef.document(userId).set(user)

You can also attach a listener to the complete operation, to see if something goes wrong.

CodePudding user response：

Similar to user creation, the setValue function can also be listened to with addOnCompleteListener, addOnSuccessListener, addOnFailureListener.

Ref: Add a Completion Callback.

You need to diagnose the result through these.
