I have implemented AdMob to My Application from this Docunemtation: Here
I can see the ad perfectly as I want. But some times I cant able to see the advertisements. If i refresh the activity, it will show me the Advertisement again. and ita work perfectly.
But when i am not able to see the advertisement at that time i got the message at catlog like:
09-27 12:58:54.451: INFO/Ads(940): onFailedToReceiveAd(Ad request successful, but no ad returned due to lack of ad inventory.)
I dont know where is the Problem ?
Why I am not able to see the Add sometimes ??
Please give the way if I am wrong regarding it.
Thanks.
AdMob ads appear at a specified interval depending on the network traffic. If there is no congestion in the traffic, the ads appear each time you see your app else you see the message in your log saying no ad returned. However have a quick walkthrough with your code and keep testing your app after giving some gap.
With regard to refresh, in your AdMob account, go to setting, there you can specify the time when do you want the ads to refresh. There is still a possibility of the same ads appearing again and again.
Why dont you use the latest Google AdSense-SDK? Google AdSense has good ads.
