After Banes, Alan Viverette then took to the stage to talk about how devs should embrace dark mode and went into detail on how they can implement it. But it is trying to help save eyes and battery life by offering Dark Modes on many of its apps, and that trend will continue.
Google went on to acknowledge the prevalence of white in its apps and the way it pushes devs to use it, but there could be a method to its madness.
Note that changing to Dark Mode only converts the UI colour to black background.
Banes went on to laud the introduction of dark modes, using the recent YouTube update as an example of the power benefits.
Android devices that only download apps from Google Play are 9 times less likely to get malware than devices that download apps from other sources. At full brightness, power draw dropped by 60 percent when moving from normal to dark.
Google is giving developers tools to push users into updating their apps. Google aims to support the new form factors in Android.
The session shows a bunch of fun stats and graphs that all compared a phone with a heavily white theme to one with a dark theme and how each impacted battery life. Well, despite the announcement, there's no exact time given by Google as to when we will see the API working on Android devices.
Google has also announced that in less than a year, the app has a whopping 30 million monthly users, which I am sure is earning Google some $$$.
