Answer 1

To create specific root directory and its sub folder i use this code

String root = Environment.getExternalStorageDirectory().toString();//get external storage

File myDir = new File(root + "/grocery"+"/photo/technostark");//create directory and subfolder

File dir=new File(root + "/grocery"+"/data");//create subfolder

myDir.mkdirs();

dir.mkdirs();
