Android Pie will come with wallpaper support in the always-on display feature
According to Android Pie source code, AOD wallpapers will automatically crossfade on a black screen after one minute.
Google introduced the Always-On Display (AOD) feature in Android Orio last year. Samsung was one of the first companies to support a photo with AOD features. It looks like Google has taken a cue from South Korean tech giant and is said to be bringing wallpaper support to the always-on display on Android Pie. Looks like it’s still unavailable for those who have received the Android Pie 9.0 update and they are expected to bring other features like ‘Slice’ later this fall.
According to XDA developers, they first saw hints of this feature in Android Developer Preview 1 for Google Pixel smartphones. But now they claim to have accessed the full source code and promised history and confirmed that the feature is working. The AOD feature can be found under the Ambient Display sub-heading under the Display Settings menu.
According to the first promise, in order to display wallpapers in AOD, the “supportsAmbientMode” attribute must be defined as “true” in the android.service.wallpaper metadata. The second promise states that AOD’s wallpaper will automatically hide after one minute. “Hide wallpaper with cross fading back scream. This increases battery life because black pixels will not emit energy, “says Comit. By comparison, Samsung’s AOD only supports static wallpapers, not just GIFs for a while.
