Loading interstitial adMob in different threads

Question

I want to load Interstitial AdMob after 5 second, after the Activity started, in another Thread. Is this code right, or I'm duplicating Runnables? Is there a better way?

 Handler handler;
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setActivityImmersiveMode();
 setContentView(R.layout.activity_normal_mode);
 // loading ads
 handler = new Handler();
 Runnable runnable = new Runnable() {
 @Override
 public void run() {
 handler.postDelayed(new Runnable() {
 @Override
 public void run() {
 loadInterstitialAd();
 }
 }, 5000);
 }
 };
 Thread thread = new Thread(runnable);
 thread.setName("AdThread");
 thread.start();
}

Answer 1

There is no need to use Thread class you can directly do this:

// loading ads
 handler = new Handler();
 handler.postDelayed(new Runnable() {
 @Override
 public void run() {
 loadInterstitialAd();
 }
 }, 5000);

So what is happening your handler will schedule your Runnable after 5 sec, you don't have to instanciate Thread and call runnable again.
