推荐答案

SD卡路径得到这样的..

sdcard path get like..

串根= Environment.getExternalStorageDirectory（）的toString（）;

String root = Environment.getExternalStorageDirectory().toString();

新的文件（根+/ photofolder）mkdirs（）;

new File(root + "/photofolder").mkdirs();

然后就可以将文件保存到根+/photofolder/20120830025700.jpg。

Then you can save a file to root + "/photofolder/20120830025700.jpg".

你有没有要求的权限写入到SD卡上？添加下面的字​​符串为您的应用程序清单：

Have you requested permission to write onto SD card? Add the following string to you app manifest:

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
