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.

I'm making an app where a signed-in user can create another account, so in this code, another user is already signed in, check the toasts to see the order the code is being executed.
btnCreateCompany.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
firebaseAuth.createUserWithEmailAndPassword(txtCompanyEmail.getText().toString(), txtCompanyPassword.getText().toString())
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
Toast.makeText(getApplicationContext(), "THIS TOAST IS COMING UP SECOND", Toast.LENGTH_SHORT).show();
if (!task.isSuccessful())
Toast.makeText(getApplicationContext(), "SOMETHING WENT WRONG", Toast.LENGTH_SHORT).show();
else {
Toast.makeText(getApplicationContext(), "THIS TOAST IS COMING UP THIRD", Toast.LENGTH_SHORT).show();
FirebaseUser userCreated = task.getResult().getUser();
userCreated.sendEmailVerification();
userID = userCreated.getUid();//userID is a private field
}
}
}); //After reaching the third toast the code adter onComplete doesn't execute anymore
if (userID == null)
Toast.makeText(getApplicationContext(), "THIS TOAST IS COMING UP FIRST", Toast.LENGTH_SHORT).show();
else {
companyRef = db.collection("companyData").document(userID); (...) }
Creating the user is an asynchronous operation. Any code that needs access to the newly created user, needs to be inside the onComplete method or be called from there.
So something like:
btnCreateCompany.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
firebaseAuth
.createUserWithEmailAndPassword(txtCompanyEmail.getText().toString(), txtCompanyPassword.getText().toString())
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
Toast.makeText(getApplicationContext(), "THIS TOAST IS COMING UP SECOND", Toast.LENGTH_SHORT).show();
if (!task.isSuccessful()) }
Toast.makeText(getApplicationContext(), "SOMETHING WENT WRONG", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(getApplicationContext(), "THIS TOAST IS COMING UP THIRD", Toast.LENGTH_SHORT).show();
FirebaseUser userCreated = task.getResult().getUser();
userCreated.sendEmailVerification();
userID = userCreated.getUid();//userID is a private field
}
if (userID == null) {
Toast.makeText(getApplicationContext(), "THIS TOAST IS COMING UP FIRST", Toast.LENGTH_SHORT).show();
}
else {
companyRef = db.collection("companyData").document(userID); (...) }
}
});
The call to:
task.getResult().getUser();
may not work. Try to log firebaseauth.getCurrentUser() and task.getResult().getUser() inside task.isSuccessful() to better understand what's going on.
I can suggest different approaches to this if you fail to debug:
1) Set up the Firebase Admin SDK to create a new user from your app:
https://firebase.google.com/docs/auth/admin/manage-users#create_a_user
OR
2) Set up a cloud function using Node.Js like this one:
https://stackoverflow.com/a/43808854/13473423
and then call your cloud functions to create and new user from your app. Handling it on the server side means it won't interfere with the "Current" FirebaseUser and thus will work!
Check this answer on how to call cloud functions locally:
https://firebase.google.com/docs/auth/admin/manage-users#create_a_user
Maybe this works. So try to replace this line
FirebaseUser userCreated = task.getResult().getUser();
with this:
FirebaseUser userCreated = firebaseauth.getCurrentUser();
How do I keep user loged in after they have signed in one time. I have a register activity that allows the the user to provide their email address and password, and once the user clicks submit an email confirmation is sent and then takes the user to the Login Activity. However once the user gets to the Login Activity they are automatically signed in. I would first like for them to validate their email first and then be signed in and stayed signed in unless they log out. I found some answers on stack-overflow about how to keep the user signed in and how to check if they validated their email but the code that I have skips the validation step and just signs the user in once taken to the login activity.
**Check to see if user enters correct credetials **
public void loginUser(View view) {
if (userEmailEditText.getText().toString().trim().equals("") || userPasswordEditText.getText().toString().trim().equals("")) {

} else {
mAuth.signInWithEmailAndPassword(userEmailEditText.getText().toString(), userPasswordEditText.getText().toString())
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override

if (task.isSuccessful()) {
checkUserStatus();
} else {
Toast.makeText(LoginActivity.this, "incorrect info", Toast.LENGTH_SHORT).show();
}
}
});
}
}

Authenticating the user with Firebase Authentication does not require them to have validated their email address. The two steps are separate, and for good reason.
Once a user signs in, they will normally stay signed in until they sign out. Firebase restores their authentication state when you restart the app, so in most cases things should run smoothly.
If you want a user to only be sent to a certain activity if they've signed in with an account with a verified email address, you can do so with:
FirebaseUser user = mAuth.getCurrentUser();
if (user != null && user.isEmailVerified()) {
...
}
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.
I want to create a login where the user only has to put his/her mail address and verify it via email. Using firebase I have this code so far:
When the user clicks the button to login after putting the mail in the field. I try to create a new account (password is random as I don't need it). If it doesn't exists I send a verification mail. If the account exists I check with checkIfVerifiedUser if the user verified the account by clicking the mail or not.
firebaseAuth.createUserWithEmailAndPassword(email, Math.random() + "").addOnCompleteListener(new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
FirebaseUser user = firebaseAuth.getCurrentUser();
user.sendEmailVerification().addOnCompleteListener((Activity) context, new OnCompleteListener() {
#Override
public void onComplete(#NonNull Task task) {
if (task.isSuccessful()) {
Toast.makeText(context, "we sent a mail, please verify", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(context, "error", Toast.LENGTH_LONG).show();
}
}
});
checkIfVerifiedUser(email);
} else {
progressDialog.dismiss();
try {
throw task.getException();
} catch (FirebaseAuthUserCollisionException e) {
// In case the account already exists
checkIfVerifiedUser(email);
} catch (Exception e) {
Toast.makeText(context, R.string.error_auth, Toast.LENGTH_SHORT).show();
}
}
} });
Here is the method I call:
private void checkIfVerifiedUser(String email){
final FirebaseUser user = firebaseAuth.getCurrentUser();
Intent intent = new Intent(context, HomeActivity.class);
if(user != null){
user.reload();
// If the user is created, we check if the account is verified
if(user.isEmailVerified()) {
intent.putExtra(IntentEnum.ALREADYREGISTERED.getCode(), true);
}else{
intent.putExtra(IntentEnum.ALREADYREGISTERED.getCode(), false);
}
}else{
intent.putExtra(IntentEnum.ALREADYREGISTERED.getCode(), false);
}
---rest of code---
}
The problem is that I either get firebaseAuth.getCurrentUser() == null or user.isEmailVerified() always false (even if I click the link in the email I get sent).
Could anyone help me with this?
Thanks!
To solve this, you need to call checkIfVerifiedUser() method inside onComplete() method and inside the if statement.
Hope it helps.
I am currently using Firebase password authentication and this is my login method its very common.
I have an else block statement that tells the user that the login is not successful but that doesn't tell the user what specifically is wrong. How can I identify if the user entered the wrong password?
private void signIn(String email, String password, final View view) {
Log.d(TAG, "signIn:" + email);
if (!validateForm()) {
return;
}
showProgress();
// [START sign_in_with_email]
fLogInAuth.signInWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if(task.isSuccessful()) {
progressDialog.dismiss();
FirebaseUser currUser = fLogInAuth.getCurrentUser();
establishUI(currUser);
} else {
progressDialog.dismiss();
establishUI(null);
Snackbar.make(view, "Unable to login, Please try again in a few moments",Snackbar.LENGTH_LONG).show();
}
}
});
}
Use task.getException().getLocalizedMessage() inside onComplete() to get error message.
