Admob crashes android build

[yuyu]

This is my first time trying to use AdMob so i have nearly no idea on how to make it work.
Whenever i try to build the app, it just crashes leaving this ErrorLog:

Does anyone know what might be the problem?

Forwarded to developer.

[CT_Yves]

Developer says: please set Build API to 28 and retry.

[yuyu]

Setting the Build API to 28 seems to work. but now i'm having an other issue, i can't seem to make the app to show any apps no matter what i do, i checked all the Campaign IDs and they're all like they are supposed to be, so i'm not sure whats wrong.

[CT_Yves]

What version of the platform tools have you in the Android SDK Manager? if it's less than 28 update it and rebuild your app.

[yuyu]

I have it on version 28.0.2 so its probably not the problem.

[CT_Yves]

Fernando asks if you see test ads when you run this app: http://www.clickteam.com/webftp/files/mmf2/misc/Test%20AdMob%20Android.mfa

If so, then the object and libs are OK, and the problem comes from somewhere else (problem in admob account, country issue, etc not sure)

[CT_Yves]

PS: in your MFA did you correctly setup the App IDs? (not the campaign IDs) - well probably, just checking...

[yuyu]

I do see ads in the app you sent.
And i think i setup the App IDs correctly though i'm not sure,
i placed the ID AdMob's website gave me https://imgur.com/a/hxQM7Nw.

Hello any one can help ? i'm geting this message "admob now requires an application id to build correctly " From admob app i setup all perfect with ID

[CT_Yves]

AFAIK this message is displayed if the "Android App. ID" property is empty, I guess you just have to copy/paste it from the admob dashboard?
