Answer 1

このコード試してみてください：エラーは私が見つけた

Answer 2

発生したとのご質問を更新し、ログインに失敗した理由を

Log.w(TAG, "createUserWithEmail:failure", task.getException()); 
Toast.makeText(EmailPasswordActivity.this, "Authentication failed.", 
         Toast.LENGTH_SHORT).show(); 

完全な情報を取得するためにとエラーと私もこのコード行を使用してトーストを使用して印刷

Toast.makeText(LoginActivity.this, "User Authentication Failed: " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
