Exact dimensions of “not enough space” given for n

I tried setting the left & right padding margins to 0 per Not enough space to show ad (AdMob)

Error:  W/Ads: Not enough space to show ad. Needs 411x49 dp, but only has 411x49 dp.


@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        MobileAds.initialize(this, String.valueOf(R.string.ad_app_id));

        mAdView = findViewById(R.id.adView);
        AdRequest.Builder b = new AdRequest.Builder();
        b.addTestDevice((AdRequest.DEVICE_ID_EMULATOR));
        b.addTestDevice("<Redacted>");
        AdRequest adRequest = b.build();
        mAdView.loadAd(adRequest);
        initialiseView();
    }

    private void initialiseView() {
        LinearLayout mLinearLayout = findViewById(R.id.linearLayout);
        mGameView = new GameView(this);
        mLinearLayout.addView(mGameView, 0);
    }



<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

On a Nexus5X, I see "Test Ad":

Update: I am seeing this bizarre error message:

ar W/Ads: Not enough space to show ad. Needs 411x49 dp, but only has 411x49 dp.

In xml file, Change your root layout to RelativeLayout from Linear Layout and also remove "android:layout_weight="512" from first child LinearLayout.

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:paddingLeft="0dp"
    android:paddingRight="0dp">

 <RelativeLayout
    android:id="@+id/rvAd"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

    android:orientation="vertical"
    android:paddingLeft="0dp"
