I am a little bit confused between interstitialAd and PublisherInterstitialAd and DoubleClick for Publishers (DFP).
DFP is found at https://developers.google.com/mobile-ads-sdk/
As referred in https://developers.google.com/mobile-ads-sdk/download, it says "On August 1, 2014, Google Play will stop accepting new or updated apps that use the old standalone Google Mobile Ads SDK v6.4.1 or lower. You must upgrade to the Google Play version of the Mobile Ads SDK by then."
And so I have followed the instruction to import google-play-services_lib as the library in the Workspace, and referred it to my app as a library. I have also removed the GoogleAdMobAdsSdk-6.4.1.jar
in a view that it will not be supported anyway later.
Though I do not know what are the difference, I have changed all my previous interstitialAd to PublisherInterstitialAd by following https://developer.android.com/reference/com/google/android/gms/ads/doubleclick/PublisherInterstitialAd.html, and anyway, a full page ad is appeared and I think it is fine.
So
what is the difference between interstitialAd, PublisherInsterstitialAd? PublisherInsterstitialAd is just new version for interstitialAd ?
And what is DoubleClick for Publishers?
Thanks!
