How to Implement In-App Purchases  in Your Android App

In this article, we’ll check the end-to-end process of implementing in-app purchases on an Android app as well as creating in-app billing products on the Google Play console.


Google Play in-app purchases are the simplest solution to selling digital products or content on Android apps. So many app developers who want to sell digital goods or offer premium membership to users can simply use the Google Play in-app billing process for smooth and easy checkouts.

In this article, we’ll check the end-to-end process of implementing in-app purchases on an Android app as well as creating in-app billing products on the Google Play console.

If you want to dive into the code directly, here’s the repo:

Let’s get started!

An Overview of Google Play’s Billing System

Before directly jumping into the code, let’s get a basic idea of the billing system. One of the important things to know is what kind of products we can sell to users. Google Play’s billing system helps us sell the following types of digital content:

So now let’s understand each of them. The in-app purchases mainly consist of two types of items: one-time products and subscriptions.

One-time products

By the name itself, we understand that it’s a one-time purchase without a recurring charge. A one-time product is an item that users can purchase with a single, nonrecurring charge. And again, this one-time product has two different categories, as shown above:

  • A _consumable product_is one in which a user can purchase repeatedly to get access to in-app content. For example, this could be purchasing currency in a game that’ll run out in due time, and users can again purchase the consumableproduct to get currency, food, etc.
  • A _non-consumable product_is one in which a user can purchase a permanent benefit without the need of buying it again and again. Mainly, we use this kind of product to offer premium membership to users for removing ads, gaining access to a certain level in a game, etc.


By the name itself, we can understand that we’re talking about a recurring purchase to gain access to the app content.

Subscriptions get renewed automatically until they’re canceled by users, meaning users get billed until they cancel the subscription on a recurring period of time — like one month, six months, one year, etc. For example, these subscriptions are mainly used in the case of music streaming services, online magazines, etc.
