Admob 横幅广告未在 Android 4.4 (KITKAT) 中显示，但在更高的 api 级别中运行良好

Question

I am using AdMob banner ads but they are not showing in lower versions the lower version i have tested on is Android 4.4.2 Kitkat but working fine in higher Android versions. I have searched this problem but didn't find any help in other questions.Hope, i will find help here.

Gradle:

implementation 'com.google.android.gms:play-services-ads:15.0.0'

XML:

            <com.google.android.gms.ads.AdView
                xmlns:ads="http://schemas.android.com/apk/res-auto"
                android:id="@+id/adView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                 ads:adSize="BANNER"
                ads:adUnitId="ca-app-pub-3940256099942544/6300978111">
            </com.google.android.gms.ads.AdView>

Application.java:

MobileAds.initialize(getApplicationContext(), "App ID");

Fragment:

  AdView mAdView = v.findViewById(R.id.adView);
  AdRequest adRequest = new AdRequest.Builder().build();
  mAdView.loadAd(adRequest);

This is test ads UnitId.
