You can't create such a folder on sdcard. Everything that's saved onto sdcard can be accessed by other applications. If you want to create a folder which is not accessible from outside of your application use Context.getDir() method with mode set to MODE_PRIVATE:

Context ctx = getContext();
File folder = ctx.getDir("NewFolder", Context.MODE_PRIVATE);
