*Chapter 5 : サービスの作成 [#i24953d7]
この章では簡易RSSリーダーを開発し、HTTP通信を使用するアプリケーションについて解説します。
このアプリケーションは設定したRSSを取得して、一覧と詳細表示を行います。詳細画面には外部リンクを併せて表示し、タップすることで外部ブラウザが開くようにします。
新規Androidアプリケーションプロジェクトを以下の設定で作成します。
-Project Nameに「RSSReader」と入力します
-Application Nameに「RSSReader」と入力します
-Package Nameに「com.beatcraft.rssreader」と入力します
-Create Activityにチェックを入れ、「RSSReaderActivity」と入力します
