Android ad size (smart banners are not always valid)

I have encountered a very annoying AdMob problem and its banner size. The size of smart banner is really a good thing. It can do almost anything for you, related to adjusting the size of advertising, but almost No

There is a table in Google Docs that lists the sizes supported by smartbanner. It supports many sizes, but does not support the horizontal size of ordinary Android phones https://developers.google.com/mobile-ads-sdk/android-legacy/docs/admob/smart-banners

That's what it's like now: Portrait - everything's fine

Landscape - not working

So, is there any way to correctly display horizontal advertising? (this is for ads: adsize = "smart_banner". When I use ads: adsize = "banner", it will be displayed on both, but it is fixed to the size given to you by ads: adsize = "banner", so it is on a larger screen)

resolvent:

Try removing any margins or padding attributes from the parent view of the XML file

I hope this will help you
