Firebase認証createUserWithEmailAndPasswordは、私は自分のアプリケーションに認証ページを実装しようとしているAndroidの

Question

で働いていません。 私はfirebaseデータベースに電子メール認証を有効にして

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(); 
      } 
     } 
    }); 
    } 
} 

私は送信ボタンをクリックして、それをデバッグしようとすると、それはcreateUserWithEmailAndPassword機能に到達しないと。次のようにコード化されましたそれはその前に止まる。 Firebaseデータベースをチェックすると、何も追加されません。

私は何を作っているのですか？

Answer 1

それはそれはあなたをテストするエミュレータを使用していることは明らかだあなたに

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(); 
    } 

Answer 2

を助けるfirebaseで登録ページにこのコードを試してみてくださいこの場合、エミュレータをアップデートしてPlay Services 11をインストールする必要があります。
