我的Android进阶之旅------&gt;MIME类型大全

智者不为愚者谋，勇者不为怯者死。这篇文章主要讲述我的Android进阶之旅------& gt; MIME类型大全相关的知识，希望能为你提供帮助。
今天在实现一个安装apk的代码中看到一段代码为：application/vnd.android.package-archive。不知其意。所以百度了一下，了解到这是一种MIME的类型，代表apk类型。代码例如以下：

//安装apk protected void installApk(File file) { Intent intent = new Intent(); //运行动作 intent.setAction(Intent.ACTION_VIEW); //运行的数据类型 intent.setDataAndType(Uri.fromFile(file), " application/vnd.android.package-archive" ); startActivity(intent); }

格式前面为后缀名，后面为相应的MIME型（比如： " .apk" , " application/vnd.android.package-archive" 表示。.apk相应的是application/vnd.android.package-archive）

import java.io.File; public class MimeTest { /** * MIME所有类型映射 */ final static String[][] MIME_MapTable = { { " .323" , " text/h323" }, { " .3gp" , " video/3gpp" }, { " .aab" , "
