I don't really know why, but this code works for me. Maybe you should use Enviroment.getExternalStorageDirectory() rather than use "/sdcard/". Try it.

File sdCard = Environment.getExternalStorageDirectory();
        File dir = new File (sdCard.getAbsolutePath());
        dir.mkdirs();

        File out = new File(dir,filename);
        try {
            out.createNewFile();
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        DataOutputStream fo = null;

            try {
                fo = new DataOutputStream( new FileOutputStream(out));
                //write what you want to fo
                fo.close();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
