Known Issues

  • You can't use Rewarded Video and any other ad type (Banner and/or Interstitial) at same time on iOS or your app will crash with the error Multiple locks on web thread not allowed when the Reward is closed. To fix this, we need help from an iOS developer as I don't have any Apple hardware to do it by myself. You can see more details about this issue here. You can find a workaround for this issue here.

Troubleshooting

  • First of all, please make sure you're able to compile the custom template without the Admob module, this way we can isolate the cause of the issue.

  • Using the Xcode debug console for iOS and logcat for Android is the best way to troubleshoot most issues. You can filter Godot only messages with logcat using the command: adb logcat -s godot

  • ERROR_CODE_NO_FILL is a common issue with Admob, but out of the scope to this module. Here's the description on the API page: ERROR_CODE_NO_FILL: The ad request was successful, but no ad was returned due to lack of ad inventory.

  • If you're getting the error Undefined symbols for architecture armv7 compiling for iOS, you should try open up the project in xcode, go to "General" tab, remove "GoogleMobileAds.framework" from frameworks, then re-add it. Should build then. Also, make sure you have directory godot/modules/admob/ios/lib added to framework search path (“Build Settings”). More info here.
