FireBase Authentication mAuth.createUserWithEmailAndPassword(email, password) error

So I'm trying to add an Authentication and Sign in service to my app, I'm following all of the steps told on FireBase although I can't get through this part, it says that the error is
createUserWithEmailAndPassword(Java.lang.String, Java.lang.String) in
FireBaseAuth cannot be applied to (Android.widget.text,
Android.widget.text)
Thanks in advance for any help given. The code is the following:
public void Register(View view) {
Intent intent = new Intent(LoginActivity.this, BottomActivity.class);
startActivity(intent);
attemptLogin();
mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener( this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d( TAG, "createUserWithEmail:success" );
FirebaseUser user = mAuth.getCurrentUser();
updateUI( user );
} else {
Log.w(TAG, "createUserWithEmail:failed");
Toast.makeText(LoginActivity.this, "Authentication failed", Toast.LENGTH_SHORT).show();
updateUI( null );
}
}
} );
}
email/password:
private AutoCompleteTextView email;
private EditText password;

use like this
mAuth.createUserWithEmailAndPassword(email.getText().toString(), password.getText().toString()).addOnCompleteListener( this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d( TAG, "createUserWithEmail:success" );
FirebaseUser user = mAuth.getCurrentUser();
updateUI( user );
} else {
Log.w(TAG, "createUserWithEmail:failed");
Toast.makeText(LoginActivity.this, "Authentication failed", Toast.LENGTH_SHORT).show();
updateUI( null );
}
}
} );

From reading the error you're getting, it's saying that the type of the parameters you're passing are not matching what the method expects. It expects String objects. So you'd need to extract that value from your TextView and EditText.
Try passing email.getText().toString() and password.getText().toString as parameters instead of email and password.
So
mAuth.createUserWithEmailAndPassword(email.getText().toString(), password.getText().toString())...

The answer is very simple you should add a classpath 'com.google.gms:google-services:4.3.8' in dependencies of built.gradle
and then add id 'com.google.gms.google-services' in built.gradle(app)
that's all.

Firebase User Verification Email

I am using Firebase as the Backend for an Mobile Android Application. When a User registers, I would like to have a verification email sent to that user.
When the User Clicks the "SignUp" button, the following logic is run through: First of all a number of variables are set from the filled in boxes. Then a few checks are performed on validity of the filled in parameters. If the checks are passed, a user is created in the Database. This is all functioning..
Then I would like to send a verification email to the user to check if the email is valid. I have also put this in the onClick method of the Button but this is not functioning yet.
I do not receive the verification email.
What is the reason behind this and the fix?
My onCreate Method
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_sign_up_page);
setFontType();
screen = (EditText)findViewById(R.id.SchermNaam);
mail = (EditText)findViewById(R.id.EmailAdres);
knop = (Button)findViewById(R.id.SignUp_Button_SignUp);
firebaseAuth = FirebaseAuth.getInstance();
}
The onClick method for the "SignUp" Button:
public void onClickSignUpPage(View view){
String schermnaam = screen.getText().toString().trim();
String emailadres = mail.getText().toString().trim();
String paswoord = pass.getText().toString().trim();
if(TextUtils.isEmpty(schermnaam)){
Toast.makeText(this,"Schermnaam invullen", Toast.LENGTH_SHORT).show();
return;
}
if(TextUtils.isEmpty(emailadres)){
Toast.makeText(this,"Email invullen",Toast.LENGTH_SHORT).show();
return;
}
if(!schermnaam_ok(schermnaam)){
Toast.makeText(this,"schermnaam minstens 5 en maximum 15 tekens", Toast.LENGTH_SHORT).show();
return;
}
if(!paswoord_ok(paswoord)){
Toast.makeText(this,"paswoord tussen 6-12 karakters en minstens 1 cijfer", Toast.LENGTH_SHORT).show();
return;
}
firebaseAuth.createUserWithEmailAndPassword(emailadres.trim(),paswoord)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
Toast.makeText(SignUpPage.this, "Nieuwe Speler Geregistreerd", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(SignUpPage.this, SignInPage.class);
startActivity(intent);
}
else {
FirebaseAuthException e = (FirebaseAuthException) task.getException();
Toast.makeText(SignUpPage.this,"Fout in de SignUp"+e.getMessage(), Toast.LENGTH_SHORT).show();
Log.d("LoginActivity", "Failed Registration", e);
return;
}
}
});
FirebaseUser user = firebaseAuth.getCurrentUser();
user.sendEmailVerification()
.addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Email sent.");
}
}
});
}

Changed it up to a sequential procedure, as suggested by the post quoted by #cramopy. Thank you for this!
Now you first need to "Sign Up" as a user, and then verify in another step, through another button. Then I receive the confirmation email.
Here my code for the onClick method for the 2 Buttons.. From a UX point of view, need to look at how to position the buttons. This is a functional viewpoint.
public void onClickSignUpPage(View view){
String schermnaam = screen.getText().toString().trim();
String emailadres = mail.getText().toString().trim();
String paswoord = pass.getText().toString().trim();
if(TextUtils.isEmpty(schermnaam)){
Toast.makeText(this,"Schermnaam invullen", Toast.LENGTH_SHORT).show();
return;
}
if(TextUtils.isEmpty(emailadres)){
Toast.makeText(this,"Email invullen",Toast.LENGTH_SHORT).show();
return;
}
if(!schermnaam_ok(schermnaam)){
Toast.makeText(this,"schermnaam minstens 5 en maximum 15 tekens", Toast.LENGTH_SHORT).show();
return;
}
if(!paswoord_ok(paswoord)){
Toast.makeText(this,"paswoord tussen 6-12 karakters en minstens 1 cijfer", Toast.LENGTH_SHORT).show();
return;
}
firebaseAuth.createUserWithEmailAndPassword(emailadres.trim(),paswoord)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(task.isSuccessful()){
Toast.makeText(SignUpPage.this, "Nieuwe Speler Geregistreerd", Toast.LENGTH_SHORT).show();
}
else {
FirebaseAuthException e = (FirebaseAuthException) task.getException();
Toast.makeText(SignUpPage.this,"Fout in de SignUp"+e.getMessage(), Toast.LENGTH_SHORT).show();
Log.d("LoginActivity", "Failed Registration", e);
return;
}
}
});
AddDataFireBase();
}
public void onClickVerify(View view){
FirebaseUser user = firebaseAuth.getCurrentUser();
assert user != null;
user.sendEmailVerification()
.addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Email sent.");
}
else {
Log.e(TAG, "sendEmailVerification", task.getException());
Toast.makeText(SignUpPage.this,
"Failed to send verification email.",
Toast.LENGTH_SHORT).show();
}}
});
Intent intent = new Intent(SignUpPage.this, SignInPage.class);
startActivity(intent);
}

Your code should work. But I suggest you to follow the next steps to verify the email:
Create account
Check if creation was successful
Check if the email is verified with user.isEmailVerified()
Reload your user to update the instance with user.reload(). You should do this because some methods on Firebase ask you to reload or reauthenticate the user before realize some operations. Reload in this case will update the cache and data of your user.
Send the email using sendEmailVerification()
Something like:
authInstance.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener {
if (it.isSuccessful) {
//Create accountData in the database
if (it.result!!.user.isEmailVerified) {
it.result!!.user.reload()
.addOnCompleteListener {
if (it.isSuccessful) {
authInstance.currentUser!!.sendEmailVerification()
.addOnCompleteListener {
Log.i("TAG", "Yay! verificationSent")
}
} else {
//Manage error
}
}
}
} else {
//Manage error
}
}
Also, you should know that sometimes the email verification takes some time in Debug environments(at least from my experience I have saw delays of 1-3 minutes, but never on release versions).
Finally, before call user.verify() you should need to call again user.reload() to update the data of your user in the Firebase Cache, if not, even if you have click on Verify my email on the email sent to your account, the FirebaseAuthor.currentUser().isEmailVerified() will continue returning you false.

Firebase Send Verification Email doesn't work

I was wondering if anybody else has the same problem, I'm working on a project using Firebase Email and Password for login, everything works fine except Verification Email, here's the code down there does anybody else has this problem? is it belong to Google? or it's something that I'm doing it wrong?
because the signUp method works fine and the user will be created after user press the Register button, but sendVerificationEmail method never been called
this is the signUp method which includes sendVerificationEmail method:
if (checkSignUpFormFields()) {
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(LaunchActivity.this, "Your account successfully created", Toast.LENGTH_SHORT).show();
sendVerificationEmail();
FirebaseAuth.getInstance().signOut();
} else {
Toast.makeText(LaunchActivity.this, "something went wrong, Check your information",
Toast.LENGTH_SHORT).show();
updateUI(null);
}
}
});
}
and this is the method for sending verification method:
private void sendVerificationEmail(){
FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
if (user != null){
user.sendEmailVerification().addOnCompleteListener(new OnCompleteListener<Void>() {
#Override
public void onComplete(#NonNull Task<Void> task) {
if (task.isSuccessful()){
Toast.makeText(LaunchActivity.this, "Verification Email has been sent.", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(LaunchActivity.this, "Something went wrong!", Toast.LENGTH_SHORT).show();
}
}
});
}
}

There's some issue with Firebase itself, I received an Email for a registration I've made about an hour ago, it's just taking so long more than an hour or so, and must be Googles issue.

Having created a new account, I automatically enter it

Having created a new account, I automatically enter it.
How do I prevent my account from being created?
firebaseAuth.createUserWithEmailAndPassword(em, pass).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(getApplicationContext(), "Пользователь добавлен", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
} else {
Toast.makeText(getApplicationContext(), "Пользователь не добавлен", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}
});
May be need workes whis admin sdk?
May be who worked with admin sdk firebase android?
Are there any examples or lessons on working with admin sdk?
For I do not understand how to work with this.

The way I understand Firebase to work is that if the task is successful then Firebase actually actually signs in the user.
firebaseAuth.createUserWithEmailAndPassword(em, pass).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
FirebaseAuth.getInstance().getCurrentUser();
//Ther will be a current user at this point. This is the way Firebase just works.
progressDialog.dismiss();
} else {
Toast.makeText(getApplicationContext(), "Пользователь не добавлен", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}
});
So you can actually get the user after the task is successful because the user is automatically set if the task is successful. If you would not like there to be any user when the task is successful. You can call
FirebaseAuth.getInstance().signOut();
This will sign out the user and when you call
Firebase.getInstance().getCurrentUser()
This will return nothing, that way there will be no user in your system.
firebaseAuth.createUserWithEmailAndPassword(em, pass).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
FirebaseAuth.getInstance().getCurrentUser();
//Ther will be a current user at this point. This is the way Firebase just works.
FirebaseAuth.getInstance().signOut();// sign out the user
Firebase.geInstance().getCurrentUser(); // this will now be null
progressDialog.dismiss();
} else {
Toast.makeText(getApplicationContext(), "Пользователь не добавлен", Toast.LENGTH_SHORT).show();
progressDialog.dismiss();
}
}
});

Check if email and password are correct Firebase

I'm currently working on an app that shows users in a listview and when you click on a user, you get to see the details.
Now you can 'add' users by filling in editText field with his or her info. Now I want that only the person himself can add his or her info. I added a editText asking for your email and an editText asking for a password. These credentials should match an account previously created in the app in Firebase. I do not seem to accomplish it.
This is my code:
String email2 = mEmailField.getText().toString();
String pw = mPassword.getText().toString();
firebaseAuth.signInWithEmailAndPassword(email2, pw).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
When the user fills in his email and password everything works, but when the incorrect password is entered, it works as well and that should not happen. What did I do wrong?

Inside OnComplete check if the Authentication was successful.
public void onComplete(#NonNull final Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(getContext(), "Authentication Successful", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getContext(), "Authentication failed.",Toast.LENGTH_SHORT).show();
}
}

mAuth.signInWithEmailAndPassword(et_LogIn_Email.getText().toString(),et_LogIn_Pasword.getText().toString())
.addOnCompleteListener((EntryActivity) requireActivity(), new OnCompleteListener<AuthResult>() {
#SuppressLint("SetTextI18n")
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText((EntryActivity) requireActivity(), "LogIn...", Toast.LENGTH_SHORT).show();
loadingDialog.stopLoading();
gotoUiPage();
} else {
Toast.makeText((EntryActivity) requireActivity(), "Error! try again...", Toast.LENGTH_SHORT).show();
tv_LogIn_warning.setText("Enter Carefully!...");
loadingDialog.stopLoading();
}
}
})
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
tv_LogIn_warning.setText(e.getMessage());
}
});
onFailureListener provide an exception by which you handle it.
