Android Question Having a problem with Real Ads don't show in Firebase AdMobs

Lyndon Bermoy · May 29, 2020

Hi. It's been a month and I haven't figured out what causes the error of not showing the real ads in b4a. When I'm using the Test AdUnitID everything works fine and I see the test ad. But when I put my own AdUnitID using https://apps.admob.com, the ads just don't show.

Here's the error in the unfiltered logs:

I have already done that with my previous thread: https://www.b4x.com/android/forum/t...ont-using-firebase-admobs.116527/#post-740137

Erel wanted me to post again with this kind of problem since I cannot reply in the last previous thread.

Thank you so much.

The real ads are now showing using the debug keys. All thanks to you @asales

But when I created my private sign key, the real ads now won't appear but when I use debug key then it will appear. How to fix this? I want to upload my first app in Playstore.

Create an example of are you doing. Export the project and put it here.

Lyndon Bermoy · May 30, 2020

I cannot attach the file because the file is too big. It is just same with your sample here: https://www.b4x.com/android/forum/threads/the-almost-definitive-admob-example.113586/ I just downloaded this sample project of firebase admobs of yours and successfully run with my real ads coming from admobs, when i created the private sign key instead of using the default debug key, my real ads won't show. When i try to go back and replace it with the default debug key, it will show again the real ads, why is this happening?

I don't know.

Not your complete project.
Create a small example only to test the ads.
If you is using the same code of the example, the export file is not too big. You need to use the menu "File / Export As Zip".

- change the package name of the example
- create a firebase project to test, with the new package name
- download the google-services.json and use it in the example
- create new ad units in the Admob to this example
- compile the example with the test ad units and with the real ad units
- use your private key (not the debug key) to compile
- check the logs, unfiltered logs and the subs of the ads

Some tips:
1 - check if your device is not marked with developer device or beta tester in Google Console
2 - check if the sub AdFailedToLoad show any error to load the ad

asales · Jun 1, 2020

I checked your example (that you sent to me in PM) and works fine here.
This image below show the ads.
Maybe the problem could be related with the admob consent, your country or other part of the code that I don't saw.
Maybe @Erel or other members could help you here.

Lyndon Bermoy · Jun 1, 2020

Thank you sir @asales for the insights, I checked also back now the unfiltered log, it says

B4X:

type=1400 audit(0.0:6931577): avc: denied { read } for name="boot_mode" dev="sysfs" ino=5339 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:sysfs:s0 tclass=file permissive=0

Do you have any idea what's this?

I don't know also if Philippines has an admob consent here. I really don't know what to do. Purchased b4a six years ago but until now I cannot monetize my apps in Google Playstore.

Anyway, Thank you so much sir.

Lyndon Bermoy · Jun 1, 2020

Sir @Erel I really need your help..

Lyndon Bermoy · Jun 1, 2020

3 = NO_FILL: https://developers.google.com/andro.../android/gms/ads/AdRequest#ERROR_CODE_NO_FILL

It is possible that Google decided that your device is a development device and doesn't show ads. Test it on a different device.
It is highly possible that it will start working after your app is submitted to Google Play.

Thank you sir @Erel and sir @asales! I understand now why there are no errors shown. Thank you again.
