What are the best practices for developing applications compatible with multiple operating systems?

Developing cross-platform applications is a great move in both perspectives for the audience as well as from development to managing single code using Use Cross-Platform Frameworks like Flutter, and React Native. The higher part Tech team mostly took care of performance optimization for the created app to validate with all cross platforms. As part of our experience taking care of the Responsive design is one of the best things at the user experience and navigation level that we need to focus. Focus on the coding architecture like modules or Microservices so code and modules are well organised and easy to scalable and reuse things

The development platform and tools are the first step and should be compatible / portable to other operating systems natively or via some XVM (eg JVM). We need to separate platform specific code from business logic. There are OS level conditional compilations that needs to be taken care. Loosely coupled architecture is important. Configuration based systems work well and interface based design is beneficial. Microservices based architecture can work with any OS on any platform.

Developing applications that are compatible with multiple operating systems can be a challenging task, but it is essential to reach a wider audience and increase user engagement. Here are some best practices for developing cross-platform applications: 1. Use a cross-platform development framework which is backwards compatible 2. Follow platform-specific guidelines 3. Test on real devices and platforms ( not simulators ) 4. Focus on the performance of applications across all platforms. 5. Update it with each update of Platform update considering its backward compatibility.

When choosing tools for developing compatible systems, prioritize those that align with your project's requirements and ensure cross-platform compatibility. Opt for tools with strong community support, scalability, and robust security features. Consider cost-effectiveness, especially for long-term maintenance and support. Select tools that are regularly updated, future-proof, and have a reasonable learning curve to facilitate efficient development.

To adhere to standards and guidelines in application development, consistently research and apply relevant industry standards like ISO/IEC norms and W3C standards. Utilize established frameworks and libraries that embed best practices, and strictly follow language-specific coding conventions for code quality. Regularly perform compliance checks and audits, stay updated with the evolving standards, and ensure your development team is well-trained and aware of the importance of these practices.

To test applications on multiple devices and scenarios, use a combination of device emulators and real device testing to cover various hardware and screen sizes. Employ automated testing tools and cloud-based testing platforms for efficiency and broader coverage. Develop test cases for real-world user scenarios, including edge cases. Integrate testing into your CI/CD pipeline for consistent compatibility checks, and conduct performance, load, accessibility, and compliance testing to ensure robust functionality across diverse environments and user groups.

To update and maintain an application effectively, establish a regular update schedule, prioritizing bug fixes, security patches, and performance improvements. Utilize automated testing for validation before each update. Implement user feedback mechanisms to identify areas needing improvement. Keep track of dependencies and update them regularly. Use version control systems for efficient tracking of changes. Stay informed about the latest industry trends and standards to ensure the application remains relevant and secure. Finally, provide clear documentation and support for users to smoothly adapt to updates and changes.

Be careful to always think about platform independent logic, business for example And use platform independent libraries, like Ktor, Koin, and SqlDelight over platform dependent like Retrofit, Dagger, and Room

When developing applications, consider platform-independent logic and libraries. Focus on business logic that is adaptable across different platforms. Choose platform-independent libraries like Ktor, Koin, and SqlDelight, which offer more flexibility compared to platform-specific ones like Retrofit, Dagger, and Room. This approach enhances the portability and scalability of your application, making it easier to maintain and update across various platforms while ensuring a consistent user experience.
