firebaseのログインページにアクセス中にエラーが発生しました

Question

firebaseを使用してログインページを作成しようとしていますが、ユーザ登録後にログインできません。以下 は、ユーザーがクリックがそれに署名したコード

MainActivity.java

btnSignIn.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
        String email = emailText.getText().toString(); 
        String pwd = passwordText.getText().toString(); 

       if (TextUtils.isEmpty(email)){ 
        Toast.makeText(MainActivity.this,"Enter Email Id",Toast.LENGTH_SHORT).show(); 
        return; 
       } 
       if (TextUtils.isEmpty(pwd)){ 
        Toast.makeText(MainActivity.this,"Enter Password",Toast.LENGTH_SHORT).show(); 
        return; 
       } 
       if (pwd.length()<5){ 
        Toast.makeText(MainActivity.this,"Password should be atleast 5 character long",Toast.LENGTH_SHORT).show(); 
        return; 
       } 

       auth.signInWithEmailAndPassword(email,pwd).addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() { 
        @Override 
        public void onComplete(@NonNull Task<AuthResult> task) { 
         if (task.isSuccessful()){ 
          finish(); 
          Toast.makeText(MainActivity.this,"Login successful",Toast.LENGTH_SHORT); 
         } 
         else { 
          Toast.makeText(MainActivity.this,"fail",Toast.LENGTH_SHORT).show(); 
          Log.e(LOG_TAG, String.valueOf(task.getException())); 

         } 
        } 
       }); 


      } 
     });

毎回は気にしないユーザーが正しいデータか間違っ

Answer 1

に入るかどうか失敗を示していますそれは私の側からだけ誤りだった。ユーザーがサインアップするとき、私はユーザーにサインアウトせずにユーザーをログインアクティビティに直接送り込んでいました。

Firebase Docに従うと、あなたのコードのために）（この行 仕上げを削除します。

また、あなたが追加することができます。

private FirebaseAuth.AuthStateListener mAuthListener; 

// ... 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // ... 
    mAuthListener = new FirebaseAuth.AuthStateListener() { 
     @Override 
     public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) { 
      FirebaseUser user = firebaseAuth.getCurrentUser(); 
      if (user != null) { 
       // User is signed in 
       Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid()); 
      } else { 
       // User is signed out 
       Log.d(TAG, "onAuthStateChanged:signed_out"); 
      } 
      // ... 
     } 
    }; 
    // ... 
} 

@Override 
public void onStart() { 
    super.onStart(); 
    mAuth.addAuthStateListener(mAuthListener); 
} 

@Override 
public void onStop() { 
    super.onStop(); 
    if (mAuthListener != null) { 
     mAuth.removeAuthStateListener(mAuthListener); 
    } 
}
