'No Ads Found' With MoPub Native Ads and Facebook

I'm attempting to understand why I'm receiving the 'No Ads Found' error message.

Expected

Native ads from the Facebook Audience Network (FAN) to show within the Android RecyclerView feed the same way the test ad units show in the screenshot below.

Setup

I have followed the Android setup for native ads. The app is not live on the Play Store as it is still in testing.

Potential Solutions

  1. Placement ID: In MoPub Facebook was added as a network, but the wrong placement id was added. I've updated the placement id with the one generated from Facebook's Monetization Manager under the Business Manager tools.

With the correct placement ID the Facebook Ad Request Debugger is showing requests being made by MoPub.

  1. App Not Being Live: Currently the app is in test mode so it is not live on the Play Store. However, according to Facebook's documentation Your app won't be able to receive Audience Network ads until payout information has been added. Payout information has been added, but Facebook's documentation does not specify whether the app must be live as well in order to receive ads.

I've also added a test device with my phone's AAID per Facebook's testing documentation so not being live on the Play Store should not be an issue.

Under MoPub's Integrating 3rd Party Ad Networks it explains that a unique Ad Renderer is required for Facebook in addition to using a specific Facebook layout.

FacebookAdRenderer facebookAdRenderer = new FacebookAdRenderer(
new FacebookAdRenderer.FacebookViewBinder.Builder(R.layout.native_ad_list_item)
    .titleId(R.id.native_title)
    .textId(R.id.native_text)
    // Binding to new layouts from Facebook 4.99.0+
    .mediaViewId(R.id.native_main_image)
    .adIconViewId(R.id.native_icon_image)
    .adChoicesRelativeLayoutId(R.id.native_ad_choices_relative_layout)
    .advertiserNameId(R.id.native_title) // Bind either the titleId or advertiserNameId depending on the FB SDK version
    // End of binding to new layouts
    .callToActionId(R.id.native_cta)
    .build());

To know which specific layout elements to use in your XML for the MediaView, AdIconView, and AdChoices RelativeLayout in the FacebookViewBinder, please reference this sample XML layout. Additionally, depending on the Facebook SDK version you are integrating, you will need to show only either the ad title or the advertiser name. For more information about Facebook’s implementation requriements, check out this article.

Then, register your ad renderers, like below. Your classThatRegistersAdRenderers varies depending on which native ad integration you are using. Remember to register your MoPubStaticNativeAdRenderer instance last.

// MoPubRecyclerAdapter
MoPubRecyclerAdapter classThatRegistersAdRenderers = new MoPubRecyclerAdapter(...);

// MoPubStreamAdPlacer
MoPubStreamAdPlacer classThatRegistersAdRenderers = new MoPubStreamAdPlacer(...);

// MoPubAdAdapter
MoPubAdAdapter classThatRegistersAdRenderers = new MoPubAdAdapter(...);

// MoPubNative
MoPubNative classThatRegistersAdRenderers = new MoPubNative(...); 

classThatRegistersAdRenderers.registerAdRenderer(
   googlePlayServicesAdRenderer);

classThatRegistersAdRenderers.registerAdRenderer(
  flurryNativeAdRenderer);

classThatRegistersAdRenderers.registerAdRenderer(facebookAdRenderer);

classThatRegistersAdRenderers.registerAdRenderer(staticAdRender);

As you are using Mopub Mediation with Facebook, you have to use FacebookAdRenderer in place of MoPubStaticNativeAdRenderer
