Underlying Algorithm:
Basic description of algorithm in step by step form:
1.) Create a Project ProgressBarExample
2.) Put the following code in res/layout/main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=""

        <TextView android:layout_width="fill_parent"
        <ProgressBar android:layout_width="wrap_content"
        <ProgressBar android:layout_width="fill_parent"
        android:max="100" />
3.) Run the application.
Steps to Create:
1.) Open Eclipse. Use the New Project Wizard and select Android Project. Give the respective project name i.e. ProgressBarExample. Enter following information:
Project name: ProgressBarExample
Build Target: Android 2.3
Application name: ProgressBarExample
Package name: com.example.ProgressBarExample

package com.example.ProgressBarExample;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.widget.ProgressBar;
public class ProgressBarExample extends Activity {
ProgressBar myProgressBar;
int myProgress = 0;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
        new Thread(myThread).start();
private Runnable myThread = new Runnable(){
        public void run() {
                // TODO Auto-generated method stub
                while (myProgress<100){
                        catch(Throwable t){ }
        Handler myHandle = new Handler(){
                public void handleMessage(Message msg) {
                        // TODO Auto-generated method stub
