How to creat Hidden Directory Android

We can create Hidden Directory Very Simple As

File direct = new File(Environment.getExternalStorageDirectory()

                           + "/.test");

              if (!direct.exists()) {

                     if (direct.mkdir()) {

                           // directory is created;

                     }

              }

above code is create folder with name ".test" (in SD CARD) then save your data(file, video.. whatever) in this folder user cant access it in normal situations because its hidden.
