live wallpaperand code for full screen ads pop up

how to implement Interstitial Ads code in live wallpaper app .and how to time adds that appear like 4 to five ads per day

after searching a lot i have found out that only way to do that is by using air-push but now google is changing policy on push notification from now on i think only preference screen is the only place u can display ads ,…so sad now…its getting hard to earn money from live wallpaper

Got to signin and you can upload apk file and have the ads injected. you can select from multiple ad networks.
