Advertisement SDK – Flexible In-App Banner System

About the Project

To support ad delivery in a major client’s mobile app, we developed a reusable Advertisement SDK for both iOS and Android. The SDK simplifies banner ad integration by supporting both in-house and third-party ad providers through a single, consistent interface, making it easy to use and adopt across different app modules.

Business Challenge

The client needed a flexible advertising solution capable of showing banners from both their own system and an external ad network. The main challenge was building an SDK that could dynamically determine and render the right banner depending on the app’s current state.

Contributions

With multiple ad providers in scope, we proposed and built a lightweight, modular Advertisement SDK for iOS and Android designed for flexibility easy usage:

• Developed a unified API for requesting, configuring, and rendering banners
• Abstracted each ad provider behind a common interface to support switching or adding new providers easily
• Enabled dynamic UI rendering, allowing apps to simply request a banner, while the SDK determines what, when, and how to display

Reusable & Scalable Solution

The Advertisement SDK was developed as a standalone module with a unified interface. It can be integrated into any app with minimal effort, supports screen-specific ad placements, and is easily extendable to work with additional providers or new ad formats.
