[[Software/Android/アプリケーション開発テキスト]] *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
