I can make almost all apps which are usually seen in the top free apps' trends in Play Store.
So, how will I put their ads? Do they give something which involves the use of Android SDK? Or can I give them my apk file so they will incorporate their ads for me? (this doesn't seem safe though).
One solution for this may be that they give me HTML for the ad so I can put it in tasker's HTML box, but then the ad networks won't be sure if their ads are showed properly or I am showing something else over the HTML box.
Also, do I have to pay the ad networks in advance or do they only take the share from the advertisements' earnings?
