Almost no ads are shown: Change Android Adview response from HTTP protocol to HTTPS

[in...@koeck.nl]

Dear Sir/Madam,

How and where can I change the HTTP protocol of the response I get for my adview from HTTP to HTTPS?
This to enable my adview to show the ads.
When I use my own Admob ads everything works fine. Also when setting up a mediation of Admob in my DFP Small Business server everything is fine as well.
But there are almost no ads when I connect the app with the DFP server of a media agency. The majority of their inventory consists of third party networks who apparently still send ads over HTTP.
Changing the HTTP protocol of the response of the ad request will make it possible to show the ads (based on the big help from Vu Chau).

Below is the error I receive in the logcat:

Thanks for taking the time to read my question.

Kind regards,

Hi Rogier,

As I explained, responses from the media agency (ib.adnxs.com) and its third-party networks have to be served over HTTPS as well for mediation to succeed.  The team does not have knowledge of this network setup so we aren't able to provide further insights.  Apparently you could proxy/reroute the traffic and force HTTPS for the responses, but I have not tested this setup.  The networks with which you are custom-mediating will have to turn on HTTPS. 

Let us know what you find,

Hi Vu Chau,

Thanks again for your answer.
We have found a solution with some adjustments on the adserver from our media agency.

Best regards,
Rogier

Hi Vu Chau,

This post is really helpful as I am facing the same issue during Android SDK integration. I am currently adding SDKless mediation ad sources to my waterfall but 80% of the delivered ads are not rendered. I have asked the mediation partner to set up both HTTP and HTTPS test campaigns but I am able to render both in my app. 

Can I clarify with you that if the HTTP URL call is totally blocked in Android SDK? If it is not 100% blocked, what are the criteria to block HTTP URL calls? 

Best regards,

Austin

Hi Austin,

I don't have a definitive response for this, since the heuristics that handle mixed content are at the level of the Android SDK (as opposed to the Mobile Ads SDK).  The Mobile Ads SDK uses a WebView to process and render all the ad traffic, so if it receives a batch of mixed content, it will apply the latest heuristics that ship with the latest WebView APK.  That is out of scope for our team.

If, in your release, you notice a fair amount of insecure HTTP traffic coming in to your app, the WebView has a mode called MIXED_CONTENT_COMPATIBILITY_MODE that you can utilize.
