Adaptive Theme
Auto-switch dark theme & wallpapers using the ambient light sensor
新版本 2.5.1
• Upgraded to target SDK 37 (Android 17)
• Dependency updates
• Dependency updates
Adaptive Theme switches Android's system-wide theme between light and dark mode according to the ambient light sensor instead of relying on sunset or a fixed schedule. Use light mode in bright surroundings and dark mode in low light, with the threshold under your control.
It can also switch your wallpaper to match the active theme.
Features
Efficient by design
The sensor is sampled briefly after the screen turns on rather than monitored continuously. Before changing the theme, Adaptive Theme checks that the sensor is not covered by a hand or pocket. Theme changes therefore happen at screen-on and do not interrupt you while you are actively using another app.
One-time setup
Android does not normally allow regular apps to change protected system settings such as the system theme. Adaptive Theme therefore needs a one-time grant of the WRITE_SECURE_SETTINGS permission. This permission does not grant root access or allow the app to read personal data. Adaptive Theme uses it only to switch the light and dark system theme, and it is revoked when the app is uninstalled.
The guided setup offers several options:

The guided setup offers several options:
- WebADB through a simple website on a computer or secondary Android device, without installing ADB
- Shizuku and compatible Shizuku forks, required only once while granting the permission
- Root on supported devices
- A manual ADB command: adb shell pm grant dev.lexip.hecate android.permission.WRITE_SECURE_SETTINGS
