Ok, for launching Home sceen of your device use this code in your onKeyDown()

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event)  { 
    if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) { 
        // do something on back.
        Intent startMain = new Intent(Intent.ACTION_MAIN); 
        startMain.addCategory(Intent.CATEGORY_HOME); 
        startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
        startActivity(startMain); 

       this.finish(); 
        return true; 
    } 

    return super.onKeyDown(keyCode, event); 
} 

And if you want to close your application then I think either you have to close your all activities by finish() in a manner (some standard way) or using

android.os.Process.killProcess(android.os.Process.myPid()) this code kill your app. (Some ugly way..!)
