Sir, Please guide me how to use DownloadManager class with your library?

Right now I just finished doing the function you are requesting. I'm in the same situation. I hope the code still works for you.
   @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

   //Verify various permissions. Specially for R/W data in internal storage
    verificacionDePermisos();

    //I make a method in another class to verify connection to internet. You can skip this validation
    if (conexionAInternet.VerificarConexion(getApplicationContext())) {

        appUpdater = new AppUpdater(MainActivity.this)
                .setDisplay(Display.DIALOG)
                .setUpdateFrom(UpdateFrom.XML)
                .setUpdateXML("YourServer/YourDocumentWithVersionInfo.xml")
                .setCancelable(false)
                .setTitleOnUpdateAvailable("A title")
                .setButtonUpdate("A name of button")
                .setButtonDismiss(null)
                .setButtonDoNotShowAgain(null)
                .setButtonUpdateClickListener(new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {

                        //Start the download update
                        descargarActualizacion();
                    }
                })
                .setIcon(R.drawable.alert); //I have a special icon. You can upload yours in the Drawable folder of your project or skip this parameter

        appUpdater.start();

    } else {
         //Another function of another class. It doesn't matter for AppUpdater
        alerta.Error(R.string.noExisteConexionAInternet, this, true);
    }
}

public void descargarActualizacion(){

        DownloadManager.Request request = new DownloadManager.Request(Uri.parse("YourServer/YourApp.apk"));

        manager.enqueue(request);

        Toast.makeText(MainActivity.this, "Download started. Please wait...", Toast.LENGTH_LONG).show();

            solicitudDePermisos();
        }
    }
}

 //We request the missing permissions
public void solicitudDePermisos(){

    //Using simple alertDialog to explain why we need the permissions
    AlertDialog.Builder alerta = new AlertDialog.Builder(MainActivity.this);
    alerta.setMessage(R.string.solicitarPermisos);

    alerta.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            //I force to user to agree the permissions for obvious rasons. If him do not accept the permissions, I close the app
            finish();
        }
    });

    AlertDialog mostrarDialog = alerta.create();
    mostrarDialog.show();
}

//You write your code here when the download finished
BroadcastReceiver onDownloadComplete = new BroadcastReceiver(){

        Toast.makeText(MainActivity.this, "Download finished.", Toast.LENGTH_LONG).show();

    }
