Understanding the market and the user: The current market scenario must be studied and the needs of the target users must be addressed.

Supporting multiple screen types: Devices come in different sizes and shapes, which affects how you design the screens and UI elements in your apps.

Maximizing app performance: The performance of an app is affected by factors such as battery life, multimedia content, and internet access.

Securing users: The users’ data is the most valuable asset. Users' sensitive information must be protected at all times

Remaining compatible with older versions: Not all users may have upgraded or may be able to upgrade their devices.
