Developing a mobile wallet app in Android Studio involves a series of steps, ranging from designing the user interface to implementing secure payment functionalities. In this comprehensive guide, we will cover the entire process, providing detailed insights into each phase of development.
1. Define the Purpose and Scope
Before delving into development, clearly define the purpose and scope of your mobile wallet app. Consider the primary features you want to include, such as payment transactions, fund transfers, and bill payments. Decide whether you want to focus on peer-to-peer transactions, integrate with existing payment systems, or offer additional services like loyalty programs.
