Question

我正在尝试在我的应用程序中实现身份验证页面。我在我的firebase数据库中启用了电子邮件身份验证，编码如下

public class AdminLoginActivity extends AppCompatActivity {

    private Button loginButton;
    private EditText inputEmail;
    private EditText inputPassword;
    private TextView loginText;

    //private ProgressDialog progressDialog;

    //Firebase Authentication Object

    private FirebaseAuth firebaseAuth;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_admin_login);

        //progressDialog = new ProgressDialog(AdminLoginActivity.this);

        firebaseAuth = FirebaseAuth.getInstance();

        loginButton = (Button) findViewById(R.id.login_button);
        inputEmail = (EditText) findViewById(R.id.enter_email);
        inputPassword = (EditText) findViewById(R.id.enter_password);

        loginText = (TextView) findViewById(R.id.newaccount_text);

        loginButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                accountLogin();

            }
        });

        loginText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


            }
        });
    }

    private void accountLogin() {
        String email = inputEmail.getText().toString().trim();
        String password = inputPassword.getText().toString().trim();


        // valid input
        //progressDialog.setTitle("Loading...");
        //progressDialog.setMessage("Logging in...");
        //progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
        //progressDialog.show();

        // Creates a user with a given email and password in the database
                (firebaseAuth.createUserWithEmailAndPassword(email, password))
            .addOnCompleteListener(AdminLoginActivity.this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if(task.isSuccessful()) {
                //successfully signed in
                //start new activity
                Toast.makeText(AdminLoginActivity.this, "Success", Toast.LENGTH_SHORT).show();
                //progressDialog.hide();
            } else {
                Toast.makeText(AdminLoginActivity.this, "Fail", Toast.LENGTH_SHORT).show();
            }
        }
    });
    }
}

当我单击提交按钮并尝试调试它时，它无法到达createUserWithEmailAndPassword功能。它在此之前就停止了。当我检查我的Firebase数据库时，没有添加任何内容。

我犯了什么错误？

在firebase中尝试使用此代码进行注册页面，它将为您提供帮助

  private void registerUser(){

         username = editTextUsername.getText().toString();
        String password = editTextPassword.getText().toString();
        String repeatPassword = editTextRepeatPassword.getText().toString();

        //checking if email and passwords are empty
            if (validate(username, password, repeatPassword)) {
                Toast.makeText(this, "You Passed", Toast.LENGTH_SHORT).show();
            }else {
                Toast.makeText(this, "Invalid email or not match password", Toast.LENGTH_SHORT).show();
            }
        //if the email and password are not empty
        //displaying a progress dialog
        progressDialog.setMessage("Registering Please Wait...");
        progressDialog.show();

        //creating a new user
        firebaseAuth.createUserWithEmailAndPassword(username, password)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        //checking if success
                        if(task.isSuccessful()){
                            //display some message here
                            Toast.makeText(RegistrationActivity.this,"Successfully registered",Toast.LENGTH_LONG).show();
                        }else{
                            //display some message here
                            Toast.makeText(RegistrationActivity.this,"Registration Error",Toast.LENGTH_LONG).show();
                        }
                        progressDialog.dismiss();
                    }
                });
    }
    private boolean validate(String emailStr, String password, String repeatPassword) {
        Matcher matcher = VALID_EMAIL_ADDRESS_REGEX .matcher(emailStr);
        return password.length() > 0 && repeatPassword.equals(password) && matcher.find();
    }

很明显，您正在使用模拟器来测试您的应用程序。在这种情况下，您需要更新模拟器才能安装Play Services 11。
