Use internal storage like so:

String FILENAME = "hello_file";
String string = "hello world!";

FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();

On the SD card (without a rooted phone) you can't create a folder which is only accessible by your application.

But everything you write to your "internal storage" is only accessible by your application. see http://developer.android.com/guide/topics/data/data-storage.html#filesInternal
