今の問題は、私は2番目の活動で共有 県から値を取得していたときに最初のケースでは、それが値を渡しているが、私は2番目にシュレッドプリファレンスから値を取得していたときにということですそれはnullを与えるケース..私が望むユーザーがfbでログインするのか、単純なログインでログインするのかです。私は次のアクティビティで必要なパラメータを取得します。誰かが私にその方法を教えてください
これは、どのように私はanoherアクティビティで値を取得するのですか？customername = prefs.getString（AppConstants.CUSTOMERNAME、 ""）; – neha
応答にはキーと値があることを確認しましたか？応答に「CustomerID」タグがあるかどうか – Rahul
はい顧客ID、名前などがあります – neha
