from free apps how earn?

You provide any AD NETWORK ADs for my free Android App (eg Flags Game)?

I live in Cyprus can upload my App to androidpit.com Apps... If yes, from free apps how earn?

Apps earn from a lot of ways. Some people put ads on them so you can earn through the ads income. Some people get sponsors for their apps, so sponsors pay them a lot of money. Some sell advertising spots on their apps so they earn through it. Some apps get a lot of donations from their users so they earn through it.

donations how given and how controlled?
ADs Networks for Android Apps exist particularly?

After upload my first App to your store at androidpit.com how declare price for it???
