FileInputStream fis = new FileInputStream(dir);
DataInputStream dataInputStream = new DataInputStream(fis);
InputStreamReader inputStream = new InputStreamReader(dataInputStream);
BufferedReader brreader = new BufferedReader(inputStream);

while ((line = brreader.readLine()) != null) {

It is because you are calling the readline method twice in the loop, which will cause the next line to be fetched from file and that line will be skipped eventually. remove line number 17-20 and try again
