I also looked at this topic and tried some of the approaches but still I am getting the same error. But my problem is I am getting an error when I choose this theme. There's a part that they use Holo Light as a theme. I am following the tutorial from the android website. If the runtime permission for location services isn’t granted, then it uses the system time.Īdd the following code in the onCreate() method.I am having a problem in my simple application. MODE_NIGHT_AUTO – This tries to auto-detect the time from the device location APIs.MODE_NIGHT_FOLLOW_SYSTEM – Uses the system settings to determine the time of day and toggles NightMode accordingly.MODE_NIGHT_NO – Disables night mode manually.MODE_NIGHT_YES – Enables night mode manually.set the DayNight theme in our application we use the method: tDefaultNightMode() Following are the arguments allowed in the above method. Let’s replace the current theme in our application with the DayNight one. Let’s get started with our implementation by creating a new Android Studio project with empty activity. Many reader applications have already deployed this theme in their apps. This theme enhances the readability and usability of your application during the night by replacing the white flashy background with a darker one. We can do so manually or let Android detect the time of the day implicitly from your phone. Thanks to this theme, we can now toggle between the light and dark modes of our application. Android DayNight ThemeĪndroid released a new theme: with the support library 23.2.0.

If you have an app with reading materials then having night mode is helpful for ease of eyes. In this tutorial, we’ll be discussing and using the Android DayNight theme in our application.
