Now that your game is built, you will need to actually put it up on Google's Play Store. To put games up on the Google Play store, you are required to pay a one-time $25 dollar fee. This may or may not seem like a large amount of money, but it is much cheaper than the iOS App Store and is a one-time fee, so for those who are a bit more budget-conscious, you may wish to dive into Google first and make some profit before moving on to Apple's store.
