On every call of isEmailVerified() returning the false condition, Even after email verified

What actually i am doing here, When a user login to their account, Then i am checking that whatever they had verified their email address or not, If not then i am starting the EmailVerificationActivity.
From where when user click on SEND VERIFICATION EMAIL Button an Email Verification code will be sent to user's email address.
after that when user successfully verified their email address, when they click SEND VERIFICATION LINK Button again.
Instead of showing toast message
Toast.makeText(this, "Your email has been verified, Now you can login.", Toast.LENGTH_LONG).show();,
sending the Email Verification link again.
Why isEmailVerified() returning the false condition.
This is my EmailVerificationActivity

You need to reload current user information. You see the data of the user your have from authentication are old and you need to retrieve the latest. Use the reload() method for that.

How i solved the error.
private void isEmailVerified()
{
mAuth.getCurrentUser().reload().addOnSuccessListener(new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
if (mAuth.getCurrentUser()!=null)
{
boolean isEmailVerified = mAuth.getCurrentUser().isEmailVerified();
if (isEmailVerified)
{
Toast.makeText(getApplicationContext(), "Your email has been verified, Now you can login.", Toast.LENGTH_LONG).show();
}
else
{
sendVerificationEmail();
}
}
}
});
}

I used the following line to solve this problem
await FirebaseAuth.instance.currentUser!.reload();

Facebook Login loaduserprofile

}).executeAsync();
Toast.makeText(getApplicationContext(), "Login Success with Facebook", Toast.LENGTH_SHORT).show();

I expected when I login with either email or google account and then Logout without conflict. So, How should I do?

Following the document here google-signin
Just only FirebaseAuth.getInstance().signOut(); to logout
So you might have to call signOutApp() function only.

Firebase Email and password Authentication fails mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener((task)

Unable to successfully complete authentication

In the following code, I am trying to open a Login page. User will fill in email and password. When user clicks on login button, checkLogin method is called.
I understand that in the onComplete method, the 1st if block checking success (filling in email, password and clicking login) is not called. I always get the Toast message "Error login" (the else block).

For authentication with email/password, the user must first be created with createUserWithEmailAndPassword():
Tries to create a new user account with the given email address and
password. If successful, it also signs the user in into the app
This example is provided in Step 4 of the guide for password-based authentication:
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// Sign in success, update UI with the signed-in user's information
Log.d(TAG, "createUserWithEmail:success");
FirebaseUser user = mAuth.getCurrentUser();
updateUI(user);
} else {
// If sign in fails, display a message to the user.
Log.w(TAG, "createUserWithEmail:failure", task.getException());
Toast.makeText(EmailPasswordActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
updateUI(null);
}
// ...
}
});

Go to your firebase console, enable sign-in method: Email/Password or Anonymous
If it does not work, please edit your password, maybe it's too short.
