Android developers guide to develop an app for foldable smartphones

When it comes to Android app development for foldable smartphones, then there are certain things that a developer should keep in mind.

  • Defining the two states

Every foldable smartphone consists of two states i.e. folded state and unfolded state. The unfolded state is the area that gets expanded when the phone converts into a tablet providing beautiful UI.

  • Resizable feature

The feature of resizable is the best feature of foldable smartphones as the screen can become small and large at the same time providing with multi-window mode. While crafting the app, the developer should make sure that the app should run flawlessly on both the screens. The developer can do this by setting resizeableActivity=True. Go for testing the behaviour of your app in the split-screen or using a Foldable emulator.

  • Design compatibility with one & two-hands

As the foldable smartphones are different from the traditional ones, people will use their one hand in the unfolded state and after it will get converted to a bigger size, they will use their second hand also.
