Why does an Admob banner ad doesn't show to me? [Android, libGDX]

Question

I have a problem:

I've installed an Admob ad banner in my app and when I'm using this command to builder:

builder.addTestDevice(
            "0277F42DBB49E3FD56F9EFFE3C4380B4"
)

Everything works (I mean, I see banner with similar text "congrats, bla-bla-bla, etc".

But.

In published game, which of course has disabled this line (addTestDevice) it doesn't show.

        RelativeLayout layout = new RelativeLayout(this);

        adView.setAdListener(new AdListener(){

    }

MainClass.java

    public class MainClass extends Game {

    public static UrlOpener urlOpener;
    public static AdHandler adHandler;

    public MainClass(UrlOpener urlOpener,
                     AdHandler adHandler)
    {
        this.urlOpener = urlOpener;
        this.adHandler = adHandler;
        adHandler.showAds(false);
    }

    @Override
    public void create() {
        Assets.getInstance().load();
        Assets.getInstance().assetManager.finishLoading();
        setScreen(new ScreenModified(this));
    }

}

Some fragment from code, where ads are called to show.

MainClass.adHandler.showAds(true);

Also, I have 0 requests from mine app.

Ads working fine with addTestDevice(XXX) but not getting live Ads.

Follow these steps :

1. Wait for some times/hours or a day.
2. If you're able to load/get test ads but not live ads, It sounds like an issue with your AdMob account.
3. After waiting still having problem then you need to cross check Ad unit Id and AppId from AdMob account.
4. Make sure that you properly set up a payment system and/or verified your PIN? If they are not done, then live ads would not be served from your account.
5. Still problem now you need to post your problem in this group for assistance.
