why no ad that test id ?

[哈哈不想哈哈]

hi 

Why can't the ads load? Keep reporting for no fill?
I am using the test id in the document, never loading the ads, always no fill, why?
On the same test machine, using the official demo, or using a new project load test id can be loaded into the AD, why put into the project, there is no advertising? I promise the loading mode is exactly the same without any difference.

Looking forward to your reply

thanks

To add to that, I'm android development

To add a note, why creating a package name can be loaded into a test AD, but my project package name loading a test AD will always nofill?
I promise the loading logic is identical just with a different package name.

Thank you for contacting the Mobile Ads SDK support team.

This will help us investigate further.

Yes, I am using the official demo provided on your documentation.

I just changed the applicationId to my project package name, the AD is always NoFill, I wonder why? This will prevent me from testing our project.

I will submit the problematic project to the link of your reply. Please check the test in time and help to check the problem. Thank you.

To add that, I saw from other questioners that you said there was a question of app-ads.text, so I checked the document of our project, the app-ads.text of the project is fully available and there is no problem.

Hi,

Thank you for getting back to us.

The Error code 3, no fill error means that the ad request was successful, but no ad was returned due to lack of ad inventory. Kindly note that the SDK just requests ads to the ad server and does not have any control on the ads it serves. I would recommend that you refer to AdMob Error Codes & Logs for more details about the issue.

Please note that we didn’t receive the files which you have shared. Could you kindly reshare the files again?

To facilitate our investigation and provide a resolution, please provide your package name and test ad unit ID via the "reply to author" option.

Thanks,

Hi team, it seems to happen to a lot of users. everything works in production but not in test ads. If i create a new app it's working but all my old apps not working with test ads. (everything is good on the account)
