Foldable App Development: Best Practices Guide 

Android phones are leading the foldable mobile phone market globally. Google has also put together a guide for Android developers to learn about foldables and develop apps for them. So, if you are looking to get a better understanding of how to make a foldable device app, here’s a brief overview: 

  • Responsive design is key for foldable devices, allowing apps to operate efficiently on various screen sizes, including folded and unfolded states. However, adaptive design is sometimes required to cater to the substantial differences in screen sizes and aspect ratios of folded and unfolded screens, which a responsive layout may struggle to accommodate. Adaptive layouts in apps for foldable devices, optimized for different screen sizes and configurations, ensure optimal user experience for various device orientations and postures. Given that foldable screen phones can fold in different ways, responsive and adaptive design equips your app to handle all possible foldable form factors. 
  • Ensure UI elements are reachable in all device states, place dialog boxes and pop-up menus away from the fold, and guarantee vital content is visible when the device is half opened. 
  • Foldable app development should ensure smooth transition between screens as a device folds or unfolds, ensuring a seamless user experience. Upon resuming from a pause, the app should restore its previous state, including: 
  • Preserving user-input text 
  • Reestablishing the keyboard state 
  • Returning to the same scroll position 
  • Resuming media playback from where it was paused 

In the context of foldable mobile phones, each screen layout should enhance the other. For instance, the unfolded screen should not only retain the same content as the folded screen and add value through complementary information, like product specifications or reviews. 

  • Foldables with large screens provide an excellent tablet-sized display for multitasking with multi-window mode. They also allow split-screen and sometimes free-form mode for a flexible, desktop-like user experience.  
  • From Android 12 (API level 31) onwards, all large-screen apps automatically run in multi-window mode. However, for versions as far back as Android 7.0 (API level 24), apps need to be configured to be resizable to facilitate this feature.  

Significance of Foldable App Development 

The introduction of foldable mobile phones has ushered in a new era in mobile technology, with it, an increasing need for apps explicitly tailored to these devices. Read further as we weigh in on why making apps for foldable devices is crucial. 

  • Devices with foldable screens provide a larger display area and more immersive viewing. This creates opportunities for apps to offer more engaging content, enhancing user experience and potentially increasing user engagement. 

  • The large screen on foldable devices can be divided into separate panels. This feature enhances multitasking capabilities significantly. Foldable app development while accommodating this feature can provide simultaneous functionality not achievable on smartphones. 
  • With the growing popularity of foldable devices, more and more users are adopting them. Companies that fail to optimize their apps for foldable devices risk falling behind their competitors who do. 
  • Users anticipate that all apps will work smoothly, regardless of the device's shape, when using a foldable device. Apps not explicitly designed for foldable devices may not function properly, resulting in a negative user experience. 
  • Foldable screen phones provide an excellent opportunity for creative interactions and interfaces. Companies can develop unique apps for such devices, which can help them engage with their users innovatively and provide more value. 
  • Incorporating new technology, such as foldable technology, can assist a company in establishing itself as a forward-thinking and innovative brand. This could improve the company's reputation with its customers and industry. 

So, here's the bottom line: foldable devices are here to stay, and foldable app development is a big step further in embracing new possibilities.
