  There is nothing more frustrating in mobile app monetization than a silent ad network. You have integrated the Vungle SDK (now part of Liftoff), initialized it successfully, and set up your placements. Yet, when you attempt to display an interstitial or rewarded video, you hit a wall:   Error 10001   or a persistent   false   return on   isCachedAdAvailable . For developers and monetization managers, this isn't just a bug—it represents a direct leak in potential revenue. When the Vungle SDK returns  VungleException.NO_SERVE  (Error 10001), it explicitly means the server could not provide an ad for the specific request. While this can sometimes be a legitimate lack of inventory, a  constant  Error 10001 during development or production usually indicates a specific integration flaw. This guide provides a rigorous technical breakdown of why this happens and how to fix it using modern Android (Kotlin) and iOS (Swift) implementations. Root ...

  There is nothing more frustrating in mobile development than a perfectly integrated SDK returning zero revenue. You initialized the SDK, created your Ad Unit ID, and called   loadAd() . The logs show a successful network request, but the callback fires   onAdLoadFailed   with   Error Code 204 . For a monetization manager or developer, this is a silent killer. The app isn't crashing, but the revenue pipeline is completely blocked. Error 204 is the HTTP status code for "No Content." The server received your request, understood it, and processed it successfully—but decided not to send anything back. This guide explores the architectural reasons why AppLovin MAX refuses to serve an ad and provides a rigorous, code-first approach to fixing it. The Technical Anatomy of Error 204 To fix the error, you must understand the ad auction mechanism. When your app requests an ad, a complex real-time bidding (RTB) process occurs in milliseconds. An Error 204 implies that the ...
