AdMob & Facebook Audience - ERR_CLEARTEXT_NOT_ALLOWED error

[Patrick Frei]

Hi support,

I'm using AdMob together with Facebook Audience Network SDK ("Mediation"). I've followed your integration guide on: https://developers.google.com/admob/android/mediation/facebook

Then, I've noticed that some ads from Facebook show the following error: ERR_CLEARTEXT_NOT_ALLOWED

This issue can be solved by using the following guide: 

https://developers.facebook.com/docs/audience-network/android-network-security-config/

I'd suggest to mention this Facebook guide in your AdMob Integration guide. So, developers are aware of that issue.

Best regards,

Patrick

Hi Ziv Yves,

Thank you!

Just an additional information: Although Facebook mentions in the guide that white-listing "localhost" / "127.0.0.1" is sufficient, their guide doesn't seem fully applicable for AdMob with Facebook Audience Network mediation. I could only get it work by adding the following to the network_security_config.xml:

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true" />
</network-security-config>

I know that this isn't really elegant as it allows all cleartext traffic, but at the moment, it seems to be the only solution to get rid of the error message.

Best regards,

Patrick

Hi Ziv Yves,

I found that this issue has not been solved yet.

I sometimes meet ERR_CLEARTEXT_NOT_ALLOWED when I tap the ads from Meta(Facebook).

How can I deal with this?

Hi Motohashi,

 

Thank you for providing the requested details.

 

Since this is specific to the mediation network of Meta(Facebook), can you confirm if the previous solution from the previous publisher doesn't solve the error you've encounter? If upon trying that still returns you this error, can you provide as a copy of a Charles log (see instruction here) privately capturing the error "ERR_CLEARTEXT_NOT_ALLOWED". You can provide the following details via Reply privately to author option or directly provide it to the link below.

Hi Pamela.

Thank you for your reply.

I confirmed that this solution could solve the error.

However, it enables app to allow all the http communications which can be a security hole.

> Since this is specific to the mediation network of Meta(Facebook),

OK, I would like to share this issue with Meta SDK Forum too.

Motohashi

Hi Junya,

 

Thank you for confirming this. I've raised this to the wider team for the update in our documentation if there is a possible workaround for this error in the mediation network of Meta(Facebook). In the meantime, you can keep an eye on our release notes or blog for future updates regarding this.
