Enable the new Force Dark feature by setting android:forceDarkAllowed=”true” in the app’s theme.You are to provide an alternative version for other things yourself using -night qualifier. It includes some predefined values suitable for the dark environment for basic things like text or background color. Make your app’s theme extend AppCompat.DayNight (or similar from MaterialComponents).I’ll address that at the end of the post. Moreover, there is a way to disable this behavior as well. However, it’s unlikely to be used by regular users. NOTE: The only exception here is the new Override force-dark option (introduced in Android Q) in Developer options which can force your app to be dark using the new Force Dark mode. However, users will increasingly expect your app to support it since the system level toggle is introduced in Android Q. Technically, your app is not affected in any way (even by targeting Android Q) until you explicitly opt-in. Improves visibility for users with low vision and those who are sensitive to bright light.Brings much more comfortable and eye-friendly way to use your device in a low-light environment.That’s why some manufacturers enable Dark Theme as a part of the Battery Saver mode Can significantly reduce power usage for devices with OLED display.Also, the post addresses some caveats and implementation details which are not documented or mentioned anywhere at the time of writing. That’s why I decided to gather everything in one place and provide a complete technical walkthrough of Dark Theme implementation including the latest updates in Android Q. Only 39% of apps on my device have a dark theme.
However, the majority of the apps haven’t taken advantage of it yet. In fact, it’s been there for a few years already (aka DayNight).
