Progress bars are our basic needs when we want to show something for a long time or some progress takes a long time and we want to show it’s progress.
Keeping that in mind ANDROID also has built in progress views.
There are basically two types of progress views in ANDROID.

ProgressDialog.STYLE_SPINNER and ProgressDialog.STYLE_HORIZONTAL

Take a look at this simple example that loads a progressBar on “onCreate”….

public class Example extends Activity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
    	super.onCreate(savedInstanceState);
    	setContentView(R.layout.main);
    	ProgressDialog dialog = ProgressDialog.show(Example.this, "", "Loading...", true);
    }
}

The following example shows how to draw a rectangle using the Paint Class in ANDROID. Just copy and paste the following code to your file and you are done.

package Draw2.pack;

import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.os.Bundle;
import android.view.View;

public class Draw2 extends Activity {

  @Override
  public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(new myView(this));
  }

  private class myView extends View{

      public myView(Context context) {
          super(context);
      }

      @Override
      protected void onDraw(Canvas canvas) {

          Paint myPaint = new Paint();
          myPaint.setColor(Color.GREEN);
          myPaint.setStyle(Paint.Style.STROKE);
          myPaint.setStrokeWidth(3);
          canvas.drawRect(10, 10, 100, 100, myPaint);
      }
  }
}

Please checkout the “LogCat” for the output.
If you don’t know about Logcat In Eclipse “Go to Window->showView and search for Logcat”.

package com.ip;

import android.app.Activity;
import android.content.Context;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//        WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
//        WifiInfo wifiInfo = wifiManager.getConnectionInfo();
//        int ipAddress = wifiInfo.getIpAddress();
//        String ip = intToIp(ipAddress);

StringBuffer buf = new StringBuffer();

System.out.println("build"+buf);

System.out.println("Phone Number = " + getMy10DigitPhoneNumber());
}
public String intToIp(int i) {

  return ((i >> 24 ) & 0xFF ) + "." +
  ((i >> 16 ) & 0xFF) + "." +
  ((i >> 8 ) & 0xFF) + "." +
  ( i & 0xFF) ;
}
private String getMyPhoneNumber(){
 TelephonyManager mTelephonyMgr;
 mTelephonyMgr = (TelephonyManager)
 getSystemService(Context.TELEPHONY_SERVICE);
 return mTelephonyMgr.getLine1Number();
 }

 private String getMy10DigitPhoneNumber(){
 String s = getMyPhoneNumber();
 return s.substring(2);
 }
}

The following java code helps you to show a webpage in ANDROID and enable javascript.

import android.webkit.WebViewClient;
import android.widget.TextView;
import android.widget.Toast;

public class myHTML extends Activity {

        TextView tv = (TextView)findViewById(R.id.tv);

        tv.setOnKeyListener(new OnKeyListener() {
