Get all files in all folders in internal and external storage

Question

I'm working on a project on android studio and I need help.. How can I search for a file by its name in all folders in internal and external storage??

I tried using for loop to search in internal.. And I tested if the file doesn't exist , the path will be the old path+the folder name. It didn't work out

what are you trying to do please elaborate, the question should be complete and clear with what you already tried and where you stuck — blackHawk, Apr 21 '17 at 12:52

    public void getAllDir(File dir) {
        String pdfPattern = ".pdf or .txt or .jpg etc..";

        File listFile[] = dir.listFiles();

        if (listFile != null) {
            for (int i = 0; i < listFile.length; i++) {

                if (listFile[i].isDirectory()) {
                    getAllDir(listFile[i]);
                } else {
                  if (listFile[i].getName().endsWith(pdfPattern)){
                                      //Do what ever u want

                  }
                }
            }
        }    
    }


and call this function like

getAllDir(Environment.getExternalStorageDirectory());
