Seemingly random mediation adapter failure

[A Tiny Pony]

I've had AdMob, MobFox and InMobi in medation for a long time. Recently I've tried adding Millennial Media and AppFlood as well, however, I'm experiencing some (seemingly) random errors.

The error is that sometimes when loading an ad ALL the mediation adapters decide to fail. The sequence of "Ads" log posts is this:

08-14 22:19:53.835: I/Ads(6649): Starting ad request.

I'd understand it more if it was consistent in failing. What could I possibly have done to make this happen? I'm impressed by how even the AdMobAdapter fails.

Possibly relevant changes recently:

• ProGuard settings.
• AppFlood and Millennial Media SDK+adapter.
• Using Millennial Media xmlns:mm and defined layout_width, layout_height, mm:width and mm:height for the AdView (otherwise Millennial Media ads fill entire screen).

I'm able to get all mediation adapter to work separately (I can see test ads if changing eCPM settings).

I know you said you can get each to work separately. Have you been able to get any two working (i.e. if you remove AppFlood and Millennial, does it work again)?

Thanks for your reply. I was able to fix this. I didn't realize the problem only occured in production.

The problem was in my ProGuard settings, that stripped away too much. Can't pinpoint it, but I re-did my ProGuard and it is now no longer a problem.

Hi A Tiny Pony,

I'm trying mediation for the first time. My setup is using AdMob, MobFox and InMobi like you had originally. I am getting the same mediation adapter failures in production that you mention. What have you added to ProGuard to get these networks to work? Any help would be appreciated. Thanks.
