Enhancing the Performance of Android

Abstract

Abstract: In the present day, with the increasing popularity of the android operating system, applications being built on the Android SDK draw much attention. However, some applications built on android tend to have a cumbersome interface causing inconveniences to users. This can be reduced by eliminating the redundancies during the build of these applications. List view is commonly used in android applications to arrange a list of scrollable items in a sequential order. This consumes a considerable amount of memory and CPU utilization resulting in the degradation of the applications. One proposed solution to this can be the introduction of the RecyclerView. The RecyclerView traditionally replaces the GridView and the ListView which were previously used in android applications. This improvement is achieved by recycling the views which are out of the visibility of the user inturn enhancing both the ListView as well as the GridView. Networking in android was previously a nightmare for developers where they had to retrieve and analyze their own data. Data transfer is performed in Android applications using a Web REST API. Development speed can be enhanced by efficient data analysis by utilizing a library from the entire range of REST client libraries. REST (Representational State Transfer) has become the most commonly used way for creating, publishing, and consuming Web services, exploiting JavaScript Object Notation (JSON) as a data exchange format. The most used libraries for accessing the REST Web APIs today are Android Volley and Retrofit. An android device is hindered by limited power, memory and resources. Several architectures such as MVC(Model-View-Controller), MVP(Model-view-Presenter) and MVVM(ModelView-Viewmodel) are commonly used in the development of android applications. In order to develop applications with efficient CPU utilization, reduced memory usage and a lowered execution time, the most suitable of these architectures is to be utilized
