Development of cross-platform mobile applications – promising methods and standard practices

The study reveals the current methodological aspects of the development of cross-platform mobile applications. The theoretical significance of the research lies in the generalization and analysis of software products and IDE environments that provide cross- platform development, as well as code generation utilities. The results of a comparative analysis of cross-platform development approaches and the results of a comparative analysis of cross- platform mobile application development tools are presented. The factors that slow down the development of a cross-platform application are identified. Solutions for minimizing functional losses in the conditions of building a universal software product are indicated. Data on the use of Shell scripts was provided, which will increase the efficiency of using the code generation utility. The steps for integrating common logic into native projects are identified. The practical significance of the research results is represented by the methodology for developing cross- platform mobile applications using a combination of tools to remove the identified limitations. The study contains a set of sequential actions and conclusions that the researchers came to in the process of forming a methodology for the cross-platform development of mobile applications. The methodology will allow us to develop a cross-platform software product adapted for subsequent modifications and extensions. This material can be designed in the standard of the developer company in the format of an internal document (instructions) of the developer company.
