Cannot resolve method 'setTimestampsInSnapshotsEnabled' in 'Builder'

I am trying to create a register activity to allow a user to register however I keep getting the error:
Cannot resolve method 'setTimestampsInSnapshotsEnabled' in 'Builder'"
It's only the section which has the setTimestampsInSnapshotsEnabled that is giving me the issue. Do I need an implementation?
Here is my Java code:
public class RegisterActivity extends AppCompatActivity implements View.OnClickListener
{
private static final String TAG = "RegisterActivity";
//widgets
private EditText mEmail, mPassword, mConfirmPassword;
private ProgressBar mProgressBar;
//vars
private FirebaseFirestore mDb;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
mEmail = (EditText) findViewById(R.id.input_email);
mPassword = (EditText) findViewById(R.id.input_password);
mConfirmPassword = (EditText) findViewById(R.id.input_confirm_password);
mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
findViewById(R.id.btn_register).setOnClickListener(this);
mDb = FirebaseFirestore.getInstance();
hideSoftKeyboard();
}
/**
* Register a new email and password to Firebase Authentication
* #param email
* #param password
*/
public void registerNewEmail(final String email, String password){
showDialog();
FirebaseAuth.getInstance().createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());
if (task.isSuccessful()){
Log.d(TAG, "onComplete: AuthState: " + FirebaseAuth.getInstance().getCurrentUser().getUid());
//insert some default data
User user = new User();
user.setEmail(email);
user.setUsername(email.substring(0, email.indexOf("#")));
user.setUser_id(FirebaseAuth.getInstance().getUid());
FirebaseFirestoreSettings settings = new FirebaseFirestoreSettings.Builder()
.setTimestampsInSnapshotsEnabled(true)
.build();
mDb.setFirestoreSettings(settings);
FirebaseFirestoreSettings newUserRef = mDb
.collection(getString(R.string.collection_users))
.document(FirebaseAuth.getInstance().getUid());
newUserRef.set(user).addOnCompleteListener(new OnCompleteListener<Void>() {
#Override

}
});
}
else {

If I look at the current documentation for FirebaseFirestoreSettings.Builder, I don't see any setTimestampsInSnapshotsEnabled method. So that probably explains the error message: you're trying to call a method that doesn't exist.
My guess is that your code was meant for an older version of the SDK when the method did exist. Since it doesn't exist anymore now, you either have to use the version of the SDK that the code was made for, or remove the call.
Update: it looks like timestampsInSnapshotsEnabled was removed in version 22 of the Android SDK for Firestore back in October 2020.

implementing clean architecture with realtime Firebase in AndroidStudio

Hi I want to implement clean architecture while using the realtime database but is seems that it is impossible to seperate the database from the my account screen class. Ideally I would want a DatabaseManager class that would handle all database operation (getting reading and posting to the db) but it seems that because the AuthStateChangeListener needs to be in the oncreate of my files it can't work. Does anyone know of any work-arounds? Here is the code I am using this on:
public class CreateAccountScreen extends AppCompatActivity {
private Button mRegister;
private EditText mEmail, mPassword, mCPassword, mName;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener firebaseAuthStateListener;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
getSupportActionBar().hide();
setContentView(R.layout.create_account);
//------------------------------------------------------
//I would want to put this in a seperate class
//VVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV
//------------------------------------------------------
mAuth = FirebaseAuth.getInstance();
firebaseAuthStateListener = new FirebaseAuth.AuthStateListener() {
#Override
public void onAuthStateChanged(#NonNull FirebaseAuth firebaseAuth) {
final FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user !=null){
Intent intent = new Intent(CreateAccountScreen.this, HomeScreen.class);
startActivity(intent);
finish();
return;
}
}
};
//-----------------------------------------------------
//^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
//I would want this in a seperate class
//------------------------------------------------------
mRegister = (Button) findViewById(R.id.goSignIn2);
mEmail = (EditText) findViewById(R.id.username3);
mPassword = (EditText) findViewById(R.id.password2);
mCPassword = (EditText) findViewById(R.id.password3);
mName = (EditText) findViewById(R.id.username2);
mRegister.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final String email = mEmail.getText().toString();
final String password = mPassword.getText().toString();
final String cPassword = mCPassword.getText().toString();
final String name = mName.getText().toString();
if (name.equals("") || password.equals("") || email.equals("") || !password.equals(cPassword)) {
Toast.makeText(CreateAccountScreen.this, "sign up error", Toast.LENGTH_SHORT).show();
return;
}
//------------------------------------------------------
//I would want to also put this in a seperate class
//VVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV

//DatabaseManager.createUser(email, password, name, CreateAccountScreen.this);
mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(CreateAccountScreen.this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(!task.isSuccessful()) {
Toast.makeText(CreateAccountScreen.this, "sign up error", Toast.LENGTH_SHORT).show();

[Error message][1]
[1]: https://i.stack.imgur.com/8gR62.png

Intent i = new Intent((this/activity),LoginActivity.class);
(this/activity).startActivity(i);
Check your intent properly, Intent take current activity as the first param and the activity you want to load up as the second param. Also, call startActivity(i) from the activity context becuase currently you are under the context of Firebase Listener.
Also, post the error log.

onCreate() is not running when i switch to the activity or onDataChanged is getting called first

i am working on a school project and i am using firebase authentication with email and password. i have a problem when a user sing in, then returns to the sing in page and tries to create a new account. when clicking the submit button to create his new account instead of going back to the sign in page, it goes to the users main page. this only happens if a user has already singed in and then tries to sign up another account. i have tried signin out the user when he is returning to the sign in page but it didnt work. here is my code:
sign in page:
public class SignIn extends AppCompatActivity {
EditText email,pass;
private FirebaseAuth mAuth;
FirebaseUser user;
FirebaseDatabase db;
DatabaseReference mRef;
String type,name;
public ProgressDialog pd;

type=null;
name=null;

Log.e("asd","Loginoncreate");
}

Toast.makeText(getApplicationContext(), "Please fill your information.", Toast.LENGTH_LONG).show();
}else{
pd = new ProgressDialog(this);
pd.setMessage("Signing in...");
pd.show();
mAuth.signInWithEmailAndPassword(email.getText().toString(), pass.getText().toString()).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {

}
}
public void signUp (View view){
startActivity(new Intent(SignIn.this, SignUp.class));

}
}
sign up page:

if (Rbtn.getText().equals("User")){
mRef.child("/Normal").child(user.getUid()).child("/Name").setValue(name.getText().toString());
mRef.child("/Normal").child(user.getUid()).child("/Type").setValue("user");
}else{

finish();
Log.e("as","signupUserGotoSignin");
}else{
Toast.makeText(getApplicationContext(), task.getException().getMessage(),Toast.LENGTH_LONG).show();
}
}
});
}
}
}
and here are my logs:
E/asd: Loginoncreate (this is the first message i see and its when i start up the app,then i sign in and go to user main page)
E/as: loginUser (when i sign in the first time while the is opened and go to users main page)
E/asd: Loginoncreate (When i return from the users main page)
E/asd: Signuponcreate (i go to create a new account)
E/as: signupUserGotoSignin (i create the account and want to return to the sign in page)
E/as: loginUser (here i would expect the Loginoncreate message again but i never get it, i always get this message 2 times. this message is onDataChanged)
E/as: loginUser
after i click the submit button to create the new account it never returns to the sign in page. i know that firebase is asynchronous but i dont know what i am doing wrong here. why the onCreate on sign in page never gets called and it goes immediately in the onDataChanged and takes me to the users main page?

I assume that signIn (View view) method is your signIn button click event. So,
firstly, you need to remove onClick attribute from button XML code.
android:onClick="signIn"
then, create onClick button event in onCreate() method.
Like,
Button button = findViewById(R.id.SignInbutton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//put your signIn button all code here
}
});
The same thing does in the SignUp page activity.

Okay so i put everything i have inside the onDataChange under an If statement where i check temp variable if its true, and right before i am move the user to the users main page i make that variable false. this fixed my problem but if someone have an explanation on why this was happening before i would still appreciate it. thanks

android - Adding a Custom ID to Firestore document

i"m working on a project that contains a code like this one: How to add Document with Custom ID to firestore (Angular)
When I'm about to try the app, it always crashes. But the code is all the same.
The error that I get in the LogCat is this:
Invalid document reference. Document references must have an even number of segments, but Users has 1
My full code is this:

I want the "user_id" to be the document id and NOT another id generated by Firestore.
Can someone please help? And Thanks in advance.

You're setting user_id at the beginning of your onCreate, probably when the EditText registerUsername doesn't contain any text. This means user_id will always be empty, no matter what happens in this activity.
You can't pass an empty string to document(). You need an actual string value there that's also a valid Firestore document ID. Try getting the string value in registerUsername after they've filled out the form, not before.
