please app inventor team add some new component to your platform. Like "CardView", "Admob Component" Please Please Please
App Inventor is made to be a learning tool. So don't expect that a advertising component will be added. For that you have to choose another builder like Kodular.
I agree with you, without the card view component it is terribly difficult to design a beautiful application, but I think this component will increase the minimum of the sdk that is now (which means that the application will not work on old devices)
You can create your own cardview "look" on AI2:
Regarding CardView, we did have a Google Summer of Code project that implemented that for AI2 but it hasn't been merged yet (@Susan_Lane we should revisit this).
Regarding Ad Mob, as @Peter says, we have no intention of adding advertising components as it is not part of our mission. There are extensions that will do this for you, and @pavi2410 is working on visible extensions which may allow more robust UI extension in the future.
This is true and each app developer will need to decide what is appropriate and acceptable for them. We will still pin the min SDK to 7 in the companion so attempting to use the card view in an older device will still fail, but in compiled apps it won't matter as much.
hey for this use this extention
