Analysis of mobile application functionality reuse

This work presents how C++ programming language functionality can be reused in native mobile applications. The first chapter of the main part gives a general overview of presented ar- chitecture. Different operating systems developers define different guidelines how user interface should look like. This work suggests to write user interface code in the native way and business logic code write in C++ programming language. In this way programming user interfaces lets to use standart development principles, saves time, helps to achieve better app’s performance and a user experience. The Android section introduces the Android Native Development Kit, which provides the ability to use C++ code in conjunction with the Android operating system. This section describes the advantages and disadvantages of how native methods can be called from Java code. The first part of iOS chapter presents iOS development using Objective-C programming language. This part gives an overview of how C++ code can be called using Objective-C++ prog- ramming language. In the second part of the chapter different ways of how to reuse C++ code in Swift apps is presented. One way is to express C++ libraries through the C programming lan- guage and use it directly in the Swift programming language. Another way is to access the libraries using Objective-C programming language. In the research part comparative analysis method was used to investigate different approaches of application development. Benchmarks were used to determine the characteristics of different implementations. First benchmark examines the over- head of the function call. The second benchmark examines the influence of implementation to application’s performance while executing complex calculations
