	private int Percentage = 0; //initialize percentage to 0
	Button Bstart; //Button variablr
	@Override
	protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	Bstart = (Button) findViewById(R.id.btnstart); //locate the button
	Bstart.setOnClickListener(new View.OnClickListener() //provide Onclick listener
	{
	@Override
	public void onClick(View v)
	{
	Pbar = new ProgressDialog(v.getContext()); //initialize the progress dailog
	Pbar.setMessage("Progressing Please Wait..."); // set a message for processing
	Pbar.setProgressStyle(Pbar.STYLE_HORIZONTAL); //Progress Dailog style
	Pbar.setProgress(0);
	Pbar.setMax(0);

	{
	@Override
	public void run() {
	while(Percentage < 100)
	{
	try {
	sleep(100); //make the thread sleep for 100 ms
	Percentage++; //eventally percentage will increment
	Pbar.setProgress(Percentage);
	} catch (InterruptedException e) {
	e.printStackTrace();
	}
