email未验证时如何注销用户，Firebase Auth

Question

How to sign out the user when the email is not verified, Firebase Auth, or make an error when trying to sing in and the email is not verified?

I use 'com.google.firebase:firebase-auth:19.4.0' Androidx minSdkVersion 21 targetSdkVersion 30 buildToolsVersion "30.0.2"

SingIn_Button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String email = email_login.getText().toString().trim();
                String password = password_login.getText().toString().trim();

                if (TextUtils.isEmpty(email)) {
                    email_login.setError("حقل البريد الالكتروني فارغ");
                    return;
                }

                if (TextUtils.isEmpty(password)) {
                    password_login.setError("حقل كلمة المرور فارغ");
                    return;
                }

                if (password.length() < 6) {
                    password_login.setError("يجب ان تكون كلمة المرور اكثر من 6 حروف");
                    return;
                }

                progressBar.setVisibility(View.VISIBLE);


                mFirebaseAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            Toast.makeText(SingInActivity.this, "تم تسجيل الدخول", Toast.LENGTH_SHORT).show();
                            startActivity(new Intent(getApplicationContext(), MainActivity.class));
                            finish();
                            overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_right);
                        } else {
                            Toast.makeText(SingInActivity.this, "خطأ :" + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
                            progressBar.setVisibility(View.GONE);
                        }
                    }
                });
            }
        });

Please Help And Thank You All

You'll want to check if the user has verified their email address with:

mFirebaseAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
    @Override
    public void onComplete(@NonNull Task<AuthResult> task) {
        if (task.isSuccessful()) {
            Toast.makeText(SingInActivity.this, "تم تسجيل الدخول", Toast.LENGTH_SHORT).show();
            progressBar.setVisibility(View.GONE);

            if (!task.getResult().getUser().isEmailVerified()) {
                ...
            }

        }
    }
});

If you want to sign the user out, that'd be task.getResult().getUser().signOut() .
