用 File.applicationDerectoryPath.resolv("text.txt")会报SecuriyError错误！

解决：

var _Path:File = File.applicationDirectory;
var _url:String = _Path.nativePath.toString();
_url+= "/test.txt";
var file:File = new File(_url);
var stream:FileStream=new FileStream;
stream.open(file, FileMode.WRITE);
stream.writeUTFBytes(input.text);
stream.close();

或是
把这句话var file:File =File.applicationDirectory.resolvePath("musiclist.xml");;
改成：var file:File =new File(File.applicationDirectory.resolvePath("musiclist.xml").nativePath);

要将file的文件地址改成全路径的，不能是相对路径的
转：用 File.applicationDerectoryPath.resolv("text.txt")会报SecuriyError错误！

解决：

var _Path:File = File.applicationDirectory;
var _url:String = _Path.nativePath.toString();
_url+= "/test.txt";

stream.open(file, FileMode.WRITE);
stream.writeUTFBytes(input.text);

改成：var file:File =new File(File.applicationDirectory.resolvePath("musiclist.xml").nativePath);

此方法不适用于手机平台...

var a:File = File.applicationDirectory.resolvePath("innercity.png");

安卓下:安卓下..a.nativePath为""    url为app:/innercity.png

ios下..a.nativePath为正常    url为app:/innercity.png  但是同样不可写

故绝对路径无效..
