Android各種MIMEタイプとファイルタイプのマッチングテーブル
27616 ワード
MIME:全称Multipurpose Internet Mail Extensions、多機能Internetメール拡張サービス.1992年に電子メールシステムに最も早く応用されたが、ブラウザにも応用された多目的インターネットメール拡張プロトコルである.MIMEタイプとは、ある拡張子を設定したファイルをアプリケーションで開く方法のタイプで、その拡張子ファイルがアクセスされると、ブラウザは自動的に指定されたアプリケーションを使用して開きます.クライアントがカスタマイズしたファイル名やメディアファイルの開き方を指定することが多い.
Androidでは、ファイルのMIMEタイプによって、どのアプリケーションがこれらのファイルを処理できるかを判断し、そのうちの1つのアプリケーション(オプションのアプリケーションが複数ある場合は、ユーザーが1つ指定しなければならない)を使用して処理します.
私はandroidエクスプローラ(ファイルブラウザ)を書くときに、エクスプローラでファイルを開く操作を実現したいと思っています.このとき、ファイルのMIMEタイプを使う必要があります.
