Using Threads In Android wihtout Async Task

This code is without using Async Task class (Android 1.5) For (Android 1.1 its User Task)

Its not a good way of implementing threads but works

....:-)

package com.arun;

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

public class thread extends Activity {

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

final Handler threadCallback = new Handler();

final Runnable runInUIThread = new Runnable(){

@Override

public void run() {

// TODO Auto-generated method stub

}

};

Thread t1= new Thread(){

public void run(){

sayHi();

threadCallback.post(runInUIThread);

}

};

t1.start();

System.out.println("Thread Id 1:::::"+t1.getPriority());

try {

t1.sleep(500);

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

Thread t2=new Thread(){

public void run(){

sayHello();

threadCallback.post(runInUIThread);

}

};

t2.start();

System.out.println("Thread Id 2:::::"+t2.getPriority());

try {

t2.sleep(10000);

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public void sayHello(){

System.out.println("hello");

}

public void sayHi(){

System.out.println("hi");

}

}
