Old Answer

add this in your manifest

<activityandroid:name="com.google.android.gms.ads.AdActivity"android:theme="@android:style/Theme.NoTitleBar.Fullscreen"tools:replace="android:theme"
 />

Solution 2:

If your target SDk version >= 27 then you get this error so try to add below code

voidsetRequestedOrientation(int requestedOrientation){
    if (ActivityInfo.isFixedOrientation(requestedOrientation) && !fullscreen
            && appInfo.targetSdkVersion > O) {
        thrownewIllegalStateException("Only fullscreen activities can request orientation");
    ....
    }

Solution 3:

just simply add this line in your gradle file
