私は自分のアプリにTwitteroAuthシステムを使用しています。具体的には、このチュートリアルに従ってください：http: //www.markhneedham.com/blog/2012/01/02/learning-android-authenticating-with-twitter-using-oauth /。コールバックURLに基づいてエラーが発生しているようですが、これを適切に行う方法に関する解決策や適切な情報がどこにも見つかりません。私のアプリの名前はchirpeeです。コードとエラーを投稿してください。助けていただければ幸いです。
注：多くのチュートリアルには、「app：//twitter」のようなCALLBACKURLのランダムなTwitterURLがあります。Twitter開発者を通じてアプリページに設定しようとすると、「無効なURL」になります。とりあえず、アプリの開発者ページとコードの両方で、CALLBACKURLをhttp://crownseal.ca（ランダムサイト）に設定しています。
