Air中File类获取地址的研究

Adobe帮助文档中说得比较松散和含糊，这是自己实验得到的结果 —————————————————————————————————— File.applicationDirectory url = "app:/" nativePath(IOS) = "/var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE/[app name].app"                //此文件夹是压缩包，只读 nativePath(WIN) = [绝对路径] nativePath(Android) = "" 注意：不要在应用程序目录（AIR 应用程序的安装位置）中添加或删除内容。否则会损坏 AIR 应用程序，应用程序签名也将失效。AIR 默认不允许写入应用程序目录，因为该目录并非对所有操作系统上的所有用户帐户均为可写目录 —————————————————————————————————— File.applicationStorageDirectory url = "app-storage:/" nativePath(IOS) = "/var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE/Library/Application Support/[app id]/Local Store"        //可写 nativePath(WIN) = "C:\Users\[UserName]\AppData\Roaming\[App Id]\Local Store" nativePath(Android) = "/data/data/air.[appid]/ [appid]/Local Store" —————————————————————————————————— File.documentsDirectory url = "file:///var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE/Documents"        //可写 url(Android)  = "file:///storage/emulated/0" nativePath(IOS)  = "/var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE/Documents" nativePath(WIN)  = "d:\Documents\[UserName]\My Documents" nativePath(Android) = "/storage/emulated/0" ——————————————————————————————————  File.desktopDirectory               url = "file:///var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE/Desktop" nativePath(IOS)  = "/var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE/Desktop"        //可写 nativePath(WIN)  = "d:\Documents\[UserName]\Desktop" ——————————————————————————————————  File.userDirectory            url = "file:///var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE" url(Android) = "file:///storage/emulated/0" nativePath(IOS)  = "/var/mobile/Applications/6D8923A6-2B86-4C46-AE7A-7B6AFB349DDE"               //可写 nativePath(WIN)  = "C:\Users\[UserName]" nativePath(Android)  = "/storage/emulated/0" ——————————————————————————————————  File.cacheDirectory nativePath(Andorid) = /data/data/air. [appid]/cache url( Andorid) = file:///data/data/air. [appid]/cache 由于AIR限制太多，实际操作中最好使用类似new File(File.applicationDirectory.resolvePath("sb.jpg").nativePath)的方式来获取File对象，保证最大权限 作者：Rainssong 来源：http://blog.sina.com.cn/rainssong 转载请保留作者信息
