public arraylist<string> getfiles(string directorypath)  {     arraylist<string> myfiles = new arraylist<string>();      file f = new file(directorypath);     f.mkdirs();     file[] files = f.listfiles();      if (files.length == 0) return null;      else {         (int i=0; i<files.length; i++)           myfiles.add(files[i].getname());     }      return myfiles; }

and called function passing enviroment.getexternalstoragedirectory()

public arraylist<string> searchpdfinexternalstorage(file folder) {         arraylist<string> myfiles = new arraylist<string>();          if (folder != null) {             if (folder.listfiles() != null) {                 (file file : folder.listfiles()) {                     if (file.isfile()) {                         //.pdf files                         if (file.getname().contains(".pdf")) {                             myfiles.add(file.getpath());                             log.d("filepath-------", "" + file.getpath());                         }                     } else {                         searchpdfinexternalstorage(file);                     }                 }             }         }     }
