Try using the below code, This will work for u.

 public void walkdir(File dir) {
    String pdfPattern = ".pdf";

    File listFile[] = dir.listFiles();

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

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

              }
            }
        }
    }    
}

EDIT

To search on the whole sdcard call this function using

walkdir(Environment.getExternalStorageDirectory());

Have a look here

Basicly get a starting Directory and then call "list" with a filter(FilenameFilter) and then traverse sub directories. Not sure if there is a one function that does all this for you.
