Saving data on external storage

I want to save some data in the user's external directory (ie. SD card), but there seems to be a weird problem. I'm using Environment.getExternalStorageDirectory() which returns "mnt/sdcard/" (which is fine). I want to create two folders on in this directory so I do:

File main = new File(getExternalStorageDirectory() + "/my_app/some_data");
if(!main.isDirectory())
    main.mkdirs();

Now I thought this would make the directory "mnt/sdcard/my_app/some_data", but after using a file manager to look at the SD card, it turns out that this folder is created at "mnt/sdcard/my_app/mnt/sdcard/my_app/some_data", which is quite bizarre. Can anyone tell me how to fix this?
