Nothing shows up while calling a method-CodePudding

I was developing an exam score calculator app. When I want to call AD methods,advertisements don't show up.

Calculation process happens in OnCreate method:

public class resultActivity extends AppCompatActivity {
    public String responseId;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_result);
        /*Calculation...*/}

and other voids like:

public void requestAd() {
/*AD RQUESTING PROCESS...*/
}

and

 public void showAd() {
/*AD SHOWING PROCESS...*/
}

AD team gave me this code to call the method and it works well:

requestButton.setOnClickListener(v -> requestAd());
 showButton.setOnClickListener(v -> showAd());

But the Problem is I don't have buttons to call them so I tried this:

public class resultActivity extends AppCompatActivity {
    public String responseId;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_result);
        requestAd();
        showAd();

        /*Calculation...*/}

But when the activity starts ads don't show up! The whole question is I want this methods to be called while this activity starts. thank you.

Try building up the release version APK and test on it. Maybe your Ad-provider have some restrictions in debug version?

I just made another class and moved request Ad and showAd there,then made an object and called the method through object. I have to mention that i changed minor thing in requestAd but the main job was done by the object. Thank You All.
