Ad Debugger

The Ad Debugger provides detailed diagnostic information for troubleshooting ad integration issues.

info

Ad Debugger is available starting from SDK 8.20.0.

Getting Started​

Opening the Ad Debugger​

Activate the Ad Debugger by long-pressing any ad view with three fingers for 3 seconds.
On the Simulator, a two-finger long-press for 2 seconds is sufficient.

Note that to inspect an ad that failed to render, you must open the Ad Debugger through a different ad view.

Force-Enabling the Ad Debugger​

warning

Force-enabling bypasses server authentication and is intended for development and internal testing only. A warning banner will be displayed inside the Ad Debugger when force-enabled.

Force Enable​

To force-enable the Ad Debugger in your app, configure GFPAdManager as follows:

GFPAdManager.setAdDebuggerEnabled(true)

Force Open​

You can also open the Ad Debugger programmatically without a gesture:

GFPAdDebugger.forceOpenAdDebugger()

Exporting Logs​

Tap the share button in the top-right corner to export the Ad Debugger data as a .zip file. You can attach this file when filing support requests.

Ad Logs​

View ad analysis, API request/response history, event logs, and parameter configurations.
For memory efficiency, only the most recent ads up to a specified limit are shown.

  • The ad highlighted in green is the one that was used to open the Ad Debugger.
  • Each ad log displays a status tag indicating its current state:
    • Loading Ad request is in progress.
    • Empty No ad inventory available for this request (No-Fill).
    • Filled Ad was successfully received.
    • Cached Ad was loaded from the cache.
    • Viewed Ad was displayed to the user.
    • Error An error occurred during the ad request or rendering.

When ad caching is enabled, a Prefetched tag is displayed alongside the status.

Ad Details​

Selecting an ad log opens a detail view with four tabs.

Overview Tab​

  • Displays a summary of the ad's basic information.
  • For cached ads, the Cache section shows storage location, entry status, expiration, TTL, and total stored size.
  • Ad Log shows the raw API request and response for the ad call.
  • Waterfall List shows the list of ad candidates returned in the response.
  • Native Ad Style shows the style configuration returned for native ads.
  • Native Ad Validator verifies the integration status of native ad view elements.
  • Ad View Snapshot lets you explore the view hierarchy and rendering details for ads opened via gesture, or view a simple snapshot for other ads.

Events Tab​

  • Event Timeline shows the ad's lifecycle events in chronological order.
  • Event Checklist provides a quick overview of which events have fired.
  • Event Logs shows the request/response details for each event API call.

Mediation Tab​

  • Summary shows overall request latency metrics.
  • Mediation Logs shows the ad selection process for each adapter.

Params Tab​

  • Timeout Settings shows the timeout configuration for each ad format (Banner, Unified, Video, Rewarded, Interstitial). Blue-highlighted values and diagrams illustrate how timeout settings are being applied.
  • Test Mode Settings shows whether test mode is enabled for each ad provider.
  • Privacy Signals shows privacy-related configuration values.

Cached Ads​

When ad caching is enabled, you can inspect the cache status for each ad unit.

  • Ad Units — Number of ad units with caching enabled.
  • Total Cached — Total number of cached ads and their combined storage size.
  • Default Expiration — The default cache expiration period, used when the ad response does not specify one.

Ad Unit Details​

Select an ad unit to view its detailed cache log.

  • Cached Currently stored in the cache.
  • Consumed Retrieved from the cache and used.
  • Expired No longer usable due to expiration.
  • Evicted Removed to free up cache space.

SDK Info​

The SDK info screen is organized into three sub-tabs.

SDK Tab​

  • App Info shows the Publisher Code, Service Code, App Version, SDK Version, and Ad Debugger Version.
  • Settings shows current configuration such as theme, mute audio, and video ad request timeout.
  • Initialization Info shows whether the SDK initialized successfully and whether the init response was cached.

Privacy Tab​

  • App Tracking Transparency shows the ATT authorization status, IDFA, and IDFV.
  • Location shows the current location permission status.
  • SKAdNetwork shows the registered SKAdNetwork list and version.
  • GDPR / GPP shows privacy regulation settings.

Mediation Tab​

  • Shows information about mediation network adapters used to render ads from external DSP SDKs.
  • Check Pod installation status for each external DSP:
    • Initialized Pod is installed and was pre-initialized during SDK setup, enabling faster initial ad rendering.
    • Installed Pod is installed and ready to render ads from this DSP when received.
    • Not Installed Pod is not installed.
    • Not Initialized Pod is installed but failed to initialize.
    • Blocked Ad delivery is disabled for this Pod version due to a server-side block.

Device Info​

Provides a comprehensive view of the device's hardware, network, and app environment. The following items are particularly useful when diagnosing ad issues:

  • iPad Window Mode — Shows the current multitasking state (Split View, Slide Over, etc.), which is helpful for diagnosing layout-related issues on iPad.
  • Network — Shows the current network connection type and status.
  • Proxy — Detects proxy configurations and flags cases that may interfere with ad requests.
  • Ad Blocker Detection — Alerts you when an ad blocker is detected, helping quickly identify why ads may not be appearing.
