Mobile devices are becoming more and more powerful and convenient with the advent of technology. To develop quality applications for these devices in a short period of time by overcoming the constraints and limitations of mobile development, a strong understanding of mobile architecture, design patterns and design intent are key factors in application development well designed. Crashes and failures in applications, as well as poor user experience, can be avoided if good design patterns are implemented. This report aims to analyze and discuss some of the components of the comobile application platform, as well as its uses and applications in the development life cycle. Introduction Mobile devices with sophisticated features and applications have changed people's lives. There are many organizations and individuals inclined towards mobile application development. Understanding the purpose of the project plays an important role in developing a well-designed application. Design choices impact application quality, and developers' design decisions will have a significant impact on applications. Say no to plagiarism.

Defining the fundamental elements of the application encourages reusability. Therefore, the design and implementation of a set of components can be optimized. Building the most attractive design is not the only goal in mobile development as the application must not only attract users but also achieve a balance in terms of functionality, aesthetics, usability and performance. Good design not only eliminates user dissatisfaction, but can prevent crashes or malicious actions. Therefore, developers need to take several aspects into account when designing a mobile application. The design used in the mobile application affects the performance of the application. Mobile applications must be fast and reliable to be valuable in a dynamic environment. However, the limitations of the medium impose significant challenges on the design application that can meet all of these expectations. Since architectural design plays a key role in overcoming such constraints, there is a need to improve the design patterns applied in mobile application development. In this article, we aim to identify and analyze architectural or design patterns for mobile application development, implement the design patterns in mobile applications, evaluate and verify the effectiveness. In order to increase efficiency, usability and reusability, design patterns are proposed for mobile application development, and design patterns are implemented in Android application. This report is organized into: Chapter 2 outlines some of the problem statements, while Chapter 3 provides a brief overview of Mobile Computing and Mobile Application Development. Chapter 4 explains the importance of design patterns in mobile application development, followed by an analysis and implementation of the design patterns proposed in Chapter 5. In Chapter 6 we provide the evaluation of the implementation results. Chapter 7 concludes the document. Mobile computing systems can be defined as “computing systems that can be easily physically moved and whose computing capabilities can be used while being moved” [1]. Examples include laptops, personal digital assistants (PDAs), and,.
