Twitterへの接続に％＆・$ 5＃〜€の問題があります。（コードはこの下に投稿されています）
まず、すべての構成（Twitterキー、マニフェストでのコールバックなど）を行ってから、Twitterを呼び出してブラウザーを開き、Twitterにサインインしてアプリケーションを受け入れます。次に、ブラウザーがアプリケーションに戻って、 Twitterから応答を取得しますが、応答としてNULLを取得します。
誰かがこれで何が起こっているのかを見つけるのを手伝ってくれますか？

PD：私はこのチュートリアルに従います：http ：//www.androidhive.info/2012/09/android-twitter-oauth-connect-tutorial/
PD 2：問題は電話の日時（https://dev.twitter.com/discussions/374）だと思う人もいますが、私はそれを変更して動作しません
