No Ads suddenly : Could not instantiate mediation adapter: com.google.DummyAdapter

[Prat]

Hello All,
Since 9th Many of my apps are not serving ads.
There has been no change in APK (no new version release) in short no change from my side.
There has been no issue like admob/google banned my app (as status on my google play and admob console are perfectly fine).

Here is the log I found from one of my APK.

05-11 11:24:27.225: I/Ads(1341): Trying mediation network:
05-11 11:24:27.225: I/Ads(1341): Instantiating mediation adapter: com.google.DummyAdapter
05-11 11:24:27.225: W/Ads(1341): Could not instantiate mediation adapter: com.google.DummyAdapter. com.google.DummyAdapter
05-11 11:24:27.235: I/Ads(1341): No fill from any mediation ad networks.


I look forward for kind help from group.
thank you,
Prat

Hi Prat,

Thank you for reaching out. 

This message is generated by the SDK when it is unable to create a new instance of mediation adapter. 

For DummyAdapter, I would suggest you to check your mediation settings and also see if your house ads campaigns are set up correctly.

Thanks

Hi!

I have the same problem with current version of AdMob (7.3.1). Did you finally resolve the problem?

Best regards

Hi Mateusz,

A "no fill" is caused because the mediation network you have set up does not have an Ad to serve at this point. I would recommend looking into your mediation settings on AdMob.

Cheers,

Elton

What exactly means DummyAdapter? I have very simple mediation settings and I don't believe it is "no fill" situation. 

I'm really afraid that if I'll roll mediation, I'll lose impressions.

Hi Tomas,

In essence, a DummyAdapter is returned when the ad unit you're using has no networks enabled. Check to see if you have no filters (by device/country etc) enabled for your ad unit.

Hi there,

Your issue is probably different and could be related to a no fill for specific devices. If you see a DummyAdapter being returned, it's related to the way your mediation stack is setup.

Thanks,
