Many developers struggle with designing Android apps that look great on every screen — whether that be on a small phone, a large tablet, or even a foldable. Since there are thousands of Android devices across the world, it will be a nightmare to create separate layouts for every screen size.
Hence, the top app development companies stick to adaptive and responsive design techniques that help in rendering a better-scaled version of the same app in a hassle-free manner without duplicating the effort.
Why Supporting Multiple Screen Sizes Matters
Earlier this year, in August, Android’s ecosystem was vast and wide. In 2025, the market will be flooded with 24000 unique Android devices, each with different screen sizes, resolutions, and aspect ratios. (developer.android). Apps could appear out of alignment, elements can be way either small or big, or user experience could take a major hit without proper adaptive design(com)
App compatibility with all devices is the make-or-break factor for mobile app development firm, impacting both user experience and retention. Apps are expected to work effortlessly on phones, on tablets, on foldables, and on ChromeOS devices. Apps that don't evolve may soon lose users.
Adaptive Layouts vs Multiple Layouts
Normally, we have to create different layouts for each screen size and that is very time-consuming and error-prone. Instead, developers are taking adaptive layouts that build dynamically according to their context size.
Some key strategies include:
ConstraintLayout
: A flexible layout mechanism for positioning user interface elements in relation to each other and the parent container, rather than in fixed positions. This enables items to automatically adjust in size and migrate around for various displays.
Density-independent units:
Using dp for dimensions and sp for fonts ensures a consistent appearance across screens with different pixel densities. Avoid using pixels (px) directly.
Wrap_content and match_parent:
these make views grow and shrink automatically based on their content or the parent container, with a flexible layout, avoiding using hard-coded values while adjusting them.
Layout qualifiers:
Developers can declare different layouts, but only for major differences in screen sizes (for instance, layout-sw600dp for tablets) so you can also avoid writing duplicate code.
This allows the leading top app development companies to build their app once, without having to manage separate codebases.
Leveraging Modern Tools: Jetpack Compose
Android unified the app’s model for multi-screen support with Jetpack Compose — it uses a declarative UI toolkit and changed the game between the apps with respect to the dimension of the screen. It enables developers to create layouts which adapt at runtime according to window size or orientation.
Window size classes:
Based upon screen width, Compose categorises into compact, medium or expanded and can be used to know how to position UI elements.
Split views:
Devs can create single-pane phone layouts and multi-pane tablet layouts, and have them written all in the same codebase, with conditional rendering.
Adaptive components
— Spacing, alignment, and style are adjusted automatically in cases of button groups, lists, navigation, and more, depending on the available space.
Compose basically allows mobile app development firms to minimise code duplication and maintenance costs and also to provide a consistent experience across all the best suited devices.
What are the best Practices for Supporting Multiple Screens
Here are some general practices that can help with UI Adaptability regardless of whether your focus is on Apple App development for iOS or Android:
- Design for relative layouts, not absolute pixels
- Utilise vector graphics and scalable assets: Minimising the risk of distortion on high-DPI screens and eliminating the need for multiple images.
- Try to act on those emulators and real devices to test it on different sizes, orientations and also foldable states.
- Limit alternative layouts: Only define alternative layouts when the user interface really needs a major change, like going from a single-pane phone layout to a multi-pane tablet layout design.
- Use adaptive navigation, which means, bottom nav on phone, side nav on tablets or larger screens.
This process assists top app development companies to make sure that the apps stay visually consistent and user-friendly across all devices with no additional development effort.
Advantages of a Unified, Adaptive Codebase
Implementing an adaptive strategy can be beneficial for businesses investing in app development in the following ways:
Lower development cost:
One codebase for multiple devices, easier to maintain, and less time spent on bug-fixing.
Quick Build:
Updates are much quicker and there is propagation through all the devices.
Improved user experience:
Apps look neat, clean interface and professional, which basically attracts and also enhances retention and engagement.
Future-proof:
Changing our device types, like the new foldables or those giant phones (nowadays those are available at the market), just adapts without us having to rewrite things.
Even home-based companies supplying website development services can draw lessons from this approach, ensuring appropriate solutions by web apps or hybrid apps are responsive across all devices and at all resolutions.
Conclusion
Building Android apps that work on every screen size doesn’t mean double the development effort. With a focus on adaptive layouts, density-independent design, modern tools such as Jetpack Compose and strategic device testing, top app development companies can build high-quality apps quickly.
Be it a mobile app development agency or one which builds apps for Android, or an agency which does Apple app development or any other website development services, these strategies allow you to develop mobile apps that are scalable, maintainable and get ready for the ever-increasing range of devices in the market today.
