[SDKBOX] AdMob doesn't load ads on Android

How do I know there has been an error?

The method:
void adViewDidFailToReceiveAdWithError ( const std::string & name, const std::string & msg )
will be called on your listener object.
See here for further informations

Of course, thanks!

Can you tell what setting test : ā€œtrueā€ in admob settings does?

  1. Replace the placement ids with google provided test ids?
    or
  2. Apply your test device ids to ad requests?
    or something else?

test=true means add running device id as testdivice

@yinjimmy, is this still the case? because I havenā€™t been able to get a reward video in test so farā€¦

how about ca-app-pub-3940256099942544/5224354917
ad-id from https://developers.google.com/admob/android/test-ads ?
