  • Added method deprecation in public api and delegate

Version 8.3.0 (Dec. 16, 2021)

  • Internal improvements on video caching
  • Improved stability on Android 5
  • SDK is compatible with Android api level 30
  • Added method deprecation in public api and delegate

Version 8.2.1 (Jun. 4, 2021) 

  • Fixed banner crash when trying to access banner size during show while view was not fully inflated.
  • Fixed webview issue which kept on playing sound after ad closure.

Version 8.2.0 (Nov. 27, 2020) 

  • Added adID to events passed in banner ad delegate methods and to errors passed in load failure delegate methods for other ad types.
  • SDK is compatible with Android api level 29.
  • Fixed crash while trying to download assets in some cases.
  • Fixed issue that in some cases caused banners to crash in Android 4.4.4.

Version 8.1.0 (Jun. 30, 2020)

  • Added new data consent API with CCPA support.
  • Added support for Android 10 (API level 29).
  • Made banner error codes publicly accessible.
  • Improved handling of rewarded ads failure. The didCompleteRewardedVideo delegate callback is now called when a rewarded ad is dismissed due to some error.
  • Auto caching banner changed – Auto-cache sdk setting Chartboost.setAutoCacheAds() no longer affects banners. Auto-cache and auto-refresh now work directly with each banner and can be set in the ChartboostBanner object public void setAutomaticallyRefreshesContent(boolean autoRefreshEnabled).
  • Initialization always calls callback – previously when SDK was already initialized, callback was never called again. SDK now always calls didInitialize callback, even if it was previously initialized.
  • Permissions changes – Chartboost doesn’t require any additional permissions anymore. We only recommend adding optional READ_PHONE_STATE permissions for better ad performance. Without this permission we won’t be able to get important information about the user.

  • Fixed a bug where the SDK didn’t handle device settings properly for Limit Ad Tracking.
  • Fixed network issues. Previously the SDK was not able to recover properly from no internet connection and therefore was not displaying ads correctly.
  • Fixed incorrect callback call after cache failure. Cache failure was returning a show error instead of the correct cache error, which could cause an infinite loop in some edge cases.
  • Removed restrictDataCollection: method.
  • setPIDataUseConsent is deprecated and replaced by addDataUseConsent.
  • getPIDataUseConsent is deprecated and replaced by getDataUseConsent.
  • CBPIDataUseConsent is deprecated. It can be used for the legacy functionality but it is recommended to use the latest API to indicate users’ data consent status for privacy regulations including GDPR and CCPA.

Version 8.0.3 (May 27, 2020)

  • Increased ad load timeout to give more time for ads to load, especially on the first try. This was causing issues where SDK could be stuck and never recover its state.
  • Fixed a callback issue on Android 4.x. Some devices were not triggering any callbacks which could lead to increased latency for mediation.
  • Fixed an issue where the SDK would freeze after losing connectivity.

Version 8.0.2 (Mar. 26, 2020)

Version 3.3.0 (Sep. 25, 2013)

Features & Improvements:
  • ChartboostActivity and ChartboostNativeActivity are simple alternatives to implementing Chartboost in your app. Simply extend your activities from either class (depending on whether you use native activities or not), provide the app ID and signature, and you’re done!
  • Changed documentation to suggest calling Chartboost.startSession() and cb.showInterstitial(); in your activity’s onStart() method, instead of in onCreate().
  • ChartboostDefaultDelegate is a new abstract class that serves as a ChartboostDelegate. Extending from this instead will allow you to skip overriding the methods you are not interested in, at the expense of not being able to inherit from your own base class. The default implementation returns true for any method that returns a boolean in the delegate.
  • didFailToLoadUrl() is called when the result of a click in an impression fails to load.
  • Added exceptions to warn you if you have forgotten to properly exclude Chartboost from your proguard using the line -keep class com.chartboost.sdk.** { *; }

  • Fix allowing Chartboost servers to differentiate buggy Android 2.x devices that all share the same ANDROID_ID
  • Fixed an infrequent HTTP connection error during image downloads.
  • Fixed bug where if the network is lost while viewing the MoreApps page, a click would cause a progress bar to hang forever.
  • Fixed edge case crashes related to caching images.
  • Method Chartboost.orientation() is now called getOrientation()
  • Added ability to disable animations and fixed animation type none
  • Fixed memory leak that could sometimes occur with the activity impressions setting.
  • Removed dependence of sensor listener unless orientation is overridden.
  • Removed all dependencies on AsyncTask, ensuring full compatibility with multithreaded apps.
  • Fixed bug where screen stayed dark after closing interstitials on certain problem devices (including 4.1.2 Nexus S and Nexus 10).
  • Fixed interference with game-rate sensor listeners on certain problem devices (including 2.3.x Galaxy S1 and Galaxy S2).
  • Fixed crash when cacheInterstitial() was called off the UI thread.
  • Change: Show impression calls will immediately fail (and call delegate method) if an impression is already visible.
  • Stopped delegate method shouldDisplayLoadingViewForMoreApps() from being fired when showing interstitials.
  • Fixed delegate method shouldRequestMoreApps() was not being called as specified.
  • Fixed harmless Lint error about invalid package reference (also no longer necessary to include -dontwarn** in your proguard configuration).
