Determine the goal
The purpose of an android application must be clearly defined. The developer needs to understand what the app is all about and the solution it is expected to provide.
Build for a Target Audience
Most times, the features and functionalities of an app depend largely on who it was built for. For example, apps targeted at elderly users should ideally be relatively less sophisticated than for young people.
Focus on User Experience
Most smartphone users prefer applications with greater ease of use and fewer complications. The look and feel, navigation, speed and efficiency of an app are some of the factors that determine user experience and satisfaction.
Ensure App Compatibility
Many different versions and upgrades of smartphones and its facilities are rolled out on a daily basis. Developing your app to support these multi versions and accommodate all levels of smartphones is key.
