Environment.getExternalStorageDirectory（）。getAbsolutePath（）给你要跟SD卡路径。

Environment.getExternalStorageDirectory().getAbsolutePath() give yous SD card Path.

要获得外部SD卡的用自由空间，使用下面的代码片断。

To get the external SD card's available "free" space use following snippet.

StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath());
double sdAvailSize = (double)stat.getAvailableBlocks()
                   * (double)stat.getBlockSize();
//One binary gigabyte equals 1,073,741,824 bytes.
double gigaAvailable = sdAvailSize / 1073741824;
