Hello, I am having some issues with Chartboost Ads On Android, I have tried few things to see if i can fix this issue but nothing worked. I also contacted Chartboost Support and They said : Thanks for the follow-up. I downloaded the game and played for a few minutes while monitoring the network calls with a webdebugger (I use Charles) and noticed Chartboost successfully called and caching an ad. With that said, I continued playing the game, though did not see the Chartboost interstitial (or any other for that matter) appear. This is however good news, as we know the ads are caching to the device on bootup, however the showInterstitial call has yet to be made. What are the steps needed in the game to see the ad? When you're playing, are you seeing the ad successfully cached? I was also in contact with Sean through Support and Sent him the BBDOC file and He got no issues and he was able to create APK with Ads. So i was guessing that Issue could be my Eclipse Installation, I followed Buildbox Guides accurately again. Removed The Eclipse Folder and re-installed it back did not fix this issue. tried Admob Interstitials They did show up without any issues, The problem is only with Chartboost Ads, Another thing is I am using Admob banners and Chartboost Interstitial, Banners are appearing just fine. Any one is having the same issue ? I am failed to fix this. Screen shot of SDK manager. What is Installed with Eclipse. I am Using Buildbox Version 2.2.8 Mac OSX El Capitan and Java SDK 8 Eclipse from Buildbox Guides.
