This blog will show you how to improve the performance of cross-platform mobile applications. Let me show you the cross-platform application before I continue. Mobile cross-platform applications are built using HTML5 or JavaScript and can run on multiple platforms.
It is essential to have a responsive UI when developing multi-platform applications. Your applications must be responsive. For example, if you want an optimal adaptive web design or a mobile responsive design.
The following architecture explains how cross-platform mobile apps work and can improve performance.
The architecture shown above illustrates the performance of cross-platform applications. The response time of the application increases as hardware acceleration is required. In addition, increased script load means receiving a response takes longer. The user experience will be compromised if cross-platform apps are not designed and developed in accordance with best practices for performance.
These guidelines will help improve the performance of mobile cross-platform applications and provide a better user experience.
Write minimal Script Code: Write a little script code for UI or data processing. It is important to keep in mind that increasing the number of scripts will take more time for them to load and execute. JavaScript should always be optimized for cross-platform applications.
Load scripts runtime: Do Not give static references to script files using the script tag. The load time for the application page will increase as the number of script files and their size increases. Load the script runtime after the basic HTML page has been loaded. Create the Script DOM and set resources in the Script file using JavaScript. This will result in a faster application launch and a better experience for the user.
Optimize Your HTML UI
HTML should not contain any script-loading tags. The script will be loaded when the HTML component is requested. This increases the response time of the UI.
Never use a ladder with multiple DIV tags. Use the minimum hierarchy for HTML DIV.
Inline CSS tags are not required. Keep all CSS in a separate CSS.
Never load generated UI components directly from the server. Write a script that creates the UI based on server responses, and add it to your HTML page.
Instead of creating separate HTML pages for each page in your application, you should always use a single HTML (divided) page.
Optimize your CSS
Create a reusable CSS class for UI components.
Use CSS gradients for the background instead of images, which require large amounts of memory and take a long time to load.
Use absolute positioning CSS for elements at the bottom when required. If necessary, use absolute CSS positioning for elements at the bottom.
Avoid using elements that are fixed in position since they take longer to move and cause UI to flicker.
Load CSS files at runtime with a loader script. This will improve the response time of your application.
Use custom UI components instead of jQuery Mobile: jQuery Mobile has many UI elements. It has some drawbacks, including flickering, low performance, and the inability to customize. Create your custom UI component using CSS and HTML DIV instead of jQuery Mobile. It is possible to create customized UI elements according to the application requirements.
6 Hardware Interaction: Create a plugin that interacts with the device API layer for hardware interaction. This can be done with minimal scripting and native code optimized. PhoneGap 3 is the best option to use. Include only necessary plugins.
