Foldable devices are all the rage these days, with Samsung being the earliest to release one, and then other manufacturers falling in line. Foldable gadgets have screens that can be folded into a full-screen display that is twice the size. Foldable gadgets improve the user experience by providing an additional area for browsing the Web and reading content. Samsung has been at the forefront of foldable device development. It unveiled the Galaxy Fold, a device with a huge screen that can be unfolded.

With foldable devices on the rise, the best mobile app development company in USA will have to work more to conceive and develop apps for them.

What impact might foldable smartphones have on app development?

When viewing applications, foldable devices provide a more dynamic user experience. Users may benefit from the device being folded to a larger screen. Streaming applications can take advantage of the larger screen size to present videos in a larger format. The lifelike experience is enhanced by a larger screen.

Multitasking gets easier and more pleasurable with multi-windows. It helps users seamlessly switch among applications and tasks, enhancing the overall experience.

When it comes to the app development process, the number of test cases will undoubtedly expand. With additional manufacturers expected to release foldable smartphones in the near future, the development team will be faced with a large number of test cases. Additionally, the duration and expense to build an app for a foldable smartphone will be higher because it will necessitate extensive design, development, and testing efforts, resulting in high development expenditures.

What is the best way to create an app for a foldable device?

We’ve covered some essential elements of creating an app for a foldable tablet: 

Two-state app screen

While creating such an application, you must take into account both its foldable and non-foldable states. The first refers to the covered display, whereas the second refers to the primary display or screen. An opened folded state is when the device converts into a tablet, and a folded state is when the device seems like a regular smartphone. Because not just the screen size as well as how the person holds the smartphone varies in these phases, the entire user experience is altered. People normally use one hand to control their devices, but a foldable smartphone will demand two hands.

It should be resizable.

One distinguishing aspect of foldable smartphones would be that their displays are much larger than those of conventional devices. Multi-window mode is also available on most foldable devices.

As a mobile app development agency in USA, you must ensure that the program you create is suitable for both screen sizes and multi-window modes. The code “resizeableActivity=true” is the simplest approach to do it.

What is the purpose of this code? It tells the system that your software supports multiple windows and customizable screens.

As a result, this code aids an app’s compatibility with a multitude of displays. Foldable phones, freeform windows, and desktop screens are all examples of this.

Multi-window

One of the most significant advantages of a huge screen is the ability to run many windows on it. Previously, functionality was limited to two apps, and people could only utilize multi-screen to use two apps, which had a significant disadvantage. Just one of the two apps may be active at a time, with the other being suspended. Now, thanks to the introduction of foldable devices, somebody can use three or more applications on display at once, all of which are in the resumed/active state.

As a result, make sure the software supports multi-window. Enabling drag and drop is another option.

Change the screen ratios if necessary.

Foldable smartphones are sure to appear in a variety. Though some manufacturers choose screens that are exceptionally high, long, and thin, other phones may have screens that are thicker and smaller.

It’s critical to check your application for different screen ratios. This ensures that your application works on as many different devices as feasible.

To find the lowest and largest ratios the application can manage, use max aspect ratio and minAspectRatio.

Multi-resume

Until Android 9, just the application that was now in focus was restarted, whereas all other operations were suspended. When the smartphone is in multi-window mode meanwhile, all of the activities are restarted with the launch of Android 10. This is referred to as multi-resume. Make sure the mobile app development service in USA you choose makes your application support multi-resume to make it more efficient. 

Supporting Multiple Screens Simultaneously

Though foldable phones presently only demand one screen compatibility at the moment, there is no certainty that this will be the case in the future. Many believe that app developers will eventually be required to cater to numerous screens at the same period.

Even though it may appear frightening now, app developers will be able to handle such a transition with ease. This is as the setup for multiple screens is very comparable to the setup for projection screens on Chrome OS.

Concurrent activities on secondary and primary displays are already supported in Android 10 and higher. The multi-screen and multi-resume capability will be available on the secondary display, too, though.

When developing an app for a foldable phone, you must choose which of the two screens will be your primary display.

Whenever an activity goes to a secondary display, remember to consider window resizing, configuration changes, and context updates. You should also inform your users about this.

Conclusion

Last but not least, foldable devices are back in use. We might just have a handful right now, but the number will undoubtedly grow in the years. And it’s at this point that app developers will be more worried, as they’ll have to consider app compatibility with foldable smartphones as well. Code Craft Crew, as a capable Android and ios mobile app development company in USA, can design and develop an adaptable app for you that responds to the functioning of both foldable and non-foldable smartphones.
