android ขอคำแนะนำหน่อยคับ เรื่องเสียงในการ random โดย timer อ่ะคับ

Random rand2=new Random();
ran4=rand2.nextInt(10)+1;//imageVie4 หรือ โจท์ย
if(ran4==1)
{
imageView3.setImageResource(R.drawable.j1);
playsong1 = MediaPlayer.create(this, R.raw.songj1);
playsong1.start();
TimerTask tt = new TimerTask() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {

playsong1.start();
}
});
}
};
Timer tm = new Timer();
tm.schedule(tt, 10000);

new CountDownTimer(15000, // msec to finish
10000) {	// msec to tick
public void onTick(long millisUntilFinished) {
playsong1.start();
}
public void onFinish() {
playsong1.stop();
}
};
}
if (ran4 == 2){
imageView3.setImageResource(R.drawable.j2);
playsong2 = MediaPlayer.create(this, R.raw.songj2);
playsong2.start();

TimerTask tt = new TimerTask() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {

playsong2.start();
}
});
}
};
Timer tm = new Timer();
tm.schedule(tt, 10000);

new CountDownTimer(15000, // msec to finish
10000) {	// msec to tick
public void onTick(long millisUntilFinished) {
playsong2.start();
}
public void onFinish() {
playsong2.stop();
}
};
}
if (ran4 == 3){
imageView3.setImageResource(R.drawable.j3);
playsong3 = MediaPlayer.create(this, R.raw.songj3);
playsong3.start();

TimerTask tt = new TimerTask() {
public void run() {
runOnUiThread(new Runnable() {
public void run() {

playsong3.start();
}
});
}
};
Timer tm = new Timer();
tm.schedule(tt, 10000);

new CountDownTimer(15000, // msec to finish
10000) {	// msec to tick
public void onTick(long millisUntilFinished) {
playsong3.start();
}
public void onFinish() {

}
};
}
