Hello ko5tik,
Ok, then here is my code which is animates my ball.
package padd.testing;
import android.app.Activity;

private int box = 10;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setOffscreenBitmap();
//Button danger = (Button)findViewById(R.id.Button01);
main = new Panel(this);
setContentView(main,new ViewGroup.LayoutParams(320,480));
/*danger.setOnClickListener( new OnClickListener(){
public void onClick(View v){
if(v.isPressed()==true){
(new Thread(new AnimationLoop())).start();

});*/
(new Thread(new AnimationLoop())).start();
}

offscreen.setBitmap(scratch);
offscreen.drawColor(Color.GREEN);
}

{
direction = DIRECTION_RIGHT;
}
else if(box > 250)
{

}

}
