  You check your AdMob dashboard and see a promising statistic: a   99% Match Rate . The demand is there; Google has inventory for your users. But immediately next to it, the   Show Rate   (or Impression Rate) sits at a dismal   15-20% . For Senior Developers and Ad Ops specialists, this gap represents wasted API calls, unnecessary battery drain, and significant revenue leakage. You are successfully requesting ads, but your application fails to display them to the user. This discrepancy usually isn't a demand issue; it is an architectural flaw in how the mobile client handles ad caching, lifecycle events, and expiration logic. The Root Cause: Why Matches Don't Convert to Impressions To fix the "High Match, Low Show" paradox, we must understand the lifecycle of a programmatic ad. The Request:  Your app requests an ad. The Fill:  AdMob responds with creative assets (Match). The Wait:  The app holds the ad object in memory, waiting for a trigger (lev...

  Few things are more frustrating in Android development than a third-party SDK that fails silently. If you are integrating the Meta Audience Network (formerly Facebook Audience Network) and facing "No Fill" errors, generic load failures, or immediate crashes on Android 9+ (API 28+), the issue likely stems from strict Network Security configurations or improper lifecycle initialization. This guide provides a root cause analysis and a production-grade solution for fixing initialization failures in the Meta Audience Network SDK using Kotlin and Java. The Symptoms Developers typically encounter one of two scenarios when this implementation is broken: The "Cleartext" Crash/Error:  The app runs on Android 8.0, but fails on Android 9.0+. Logs indicate  IOException  or  Cleartext HTTP traffic to ... not permitted . The Silent Failure:   AdListener.onError  triggers immediately with generic codes, or the SDK simply never attempts to fetch an ad. Root Cause Ana...
