But the project you shared, did you import it from App Inventor or did you recreate it from scratch?
And have you tried checking all the settings in Project Settings?
As far as I know, I checked it several times, and I also checked that the app worked correctly in the Android companion app, and it didn’t give me any errors, which is what it should give if there’s some App Inventor component that’s interfering.
I was checking your project more carefully and I saw this,
does that image exist in your assets? (In the project you sent, it is not present)
In the end, I rebuilt it from scratch again to see if it was error-free, and I managed to upload it, but after a few days, the ads stopped working, and I don’t know how to talk to the developers to find out what the problem might be with the ads, since they were working for me for a week. Thanks.
Hi dear,
So is the APK generation issue resolved?
Creating it again did fix it. Thank you very much.
Can you help me with the new bug, or should I open a new thread? Thanks.
Very good 
!!!
I’d like to ask if you could kindly close this one and open a new one for the new issue.
I’ll tell you right away that I’m not an expert in ads 
, but by creating a new topic I’m sure someone will be able to give you a hand.
I’ll still try to help you as much as I can.
Of course, try first to look in the community to see if someone has had a similar problem.
