The answer is simple: applications must extend to a larger screen, stretching the screen size for improved usability. 

Let’s explore more about these challenges in the following section of our blog.

Challenges Of Developing Android Apps For Foldable Devices

Challenges Of Developing Android Apps For Foldable Devices

The primary idea behind foldable devices is to extend the screen’s usage. The combined screen allows developers to access a larger space, creating a more immersive user experience. 

However, the true challenge here is to develop mobile applications. Unlike traditional mobile apps where developers can prepare applications normally, the UX in case of large-screen requires a glitch-free experience that can maximize and minimize as per the screens.

Since the display technology used in Android foldable devices differs, the app design, UI, and UX are also different. Currently, apps for foldable devices face the following challenges: 

  • Applications that smoothly switch between folded and unfolded modes
  • screens with various orientations
  • The application’s form factor is different from conventional
  • We need to conduct more app testing in various situations.
  • Foldable cell phones come in a range of screen sizes.
  • Smartphone manufacturers offer a variety of folding smartphone designs and circumstances.
  • Longer software development cycles and greater costs

So now that we have an overview of the primary challenges let’s understand more about them in depth. 

Challenge 1: Screen Continuity

Screen Continuity

Developers must ensure screen continuity in their applications as Android foldable devices require constant switching between unfolded and folded states. They must create a seamless user experience that continues across the screen, and the resolution expands with the layout changes. 

Here, app developers’ challenge is creating ambiguity, which will increase with the screen transition. Therefore, they must create a code that minimizes or nullifies the changes happening in the application design. Besides, since the multi-window pushes the need for multitasking, developers should be wary about such features and incorporate matching design elements.

Challenge 2: Multi-Resume Support

Multi-Resume Support

Similar to the multi-tasking aspect of the application, developers need to ensure that their products support multi-resume features. This functionality allows the applications to resume functioning between unfolded and foldable screens without freezing other applications running in the background. Thanks to the Android 10 update, developers can now develop Android apps with multiple functionality. 

This update by Google allows users to open different applications besides Android 10. In the past, fold phones could only resume one application after changing the device’s orientation. Therefore, developers must keep the multi-resume functionality in mind while creating their applications to ensure a seamless user experience across different screen sizes.

Challenge 3: Multi-Window Mode

Multi-Window Mode

Every foldable device will have two states at any point: Folded and Unfolded.

When kept unfolded, a smartphone transforms into a tablet. This provides an extra screen space to give users an immersive visual and user experience. Here, developers can include more context for including secondary events or actions in their apps. On the contrary, the folded device will function as a traditional smartphone. 

The application will need a UI design that enables one-handed operation. The seamless switch between one and two-handed operation demands the efforts of the design teams to look at the critical UI/UX facets. The team needs to be aware of the Android developer options as they would be required to maintain elements within the thumb’s range for the folded device, whereas, in its unfolded state, the screen should have UI/UX elements within the finger’s reach.

Challenge 4: App Continuity

App Continuity

With foldable devices, users can access more screen resolution than traditional straight-screen devices. Thanks to the Android 10 update, the later updates support a wide range of aspect ratios. Android foldable devices can now go from thin and long screens to a 1:1 ratio. 

Therefore, the developed applications for these devices must be tested across different resolution formats. In such cases, users must define the minAspectRatio and maxAspect Ratio variables in their code to indicate the minimum and maximum resolution the application can extend or minimize. 

Impact Of Foldable Devices On Android App Development

Impact Of Foldable Devices On Android App Development

It’s a clear game-changer that foldable phones are becoming increasingly popular. To create apps operating on various screen sizes, developers must research how consumers use their phones.

The design should only undergo minor or non-pair changes. One can always switch between the unfolded and compressed modes, for instance.

The application’s many perspectives are dependent on the status of the screen. Because developers should concentrate on a comprehensive user interface and limit or erase any modifications that happen in design, the user must comprehend what the program performs and how it functions.

Designers and developers must consider the features and limits of a multi-window lifecycle. Designers must know the features, operations, and design of apps that enhance multitasking. When incorporating multitasking capabilities, programmers in a technological environment must adhere to rules.
