Google is apparently not satisfied with its Project Butter undertaking that was introduced alongside Jelly Bean, and aims to make its mobile OS even smoother going forward.
The Mountain View giant just bought FlexyCore, a French company that gave us the DroidBooster app. The application has subsequently been pulled, but that might have been since Google was evidently in talks with the developers there for over a year, until it finally acquired it for $23 million. That might mean we could see the DroidBooster optimizations embedded in Android 4.4 KitKat already, but let's see what Google announces by the end of the month.
FlexyCore specializes in Android kernel optimizations that make the mobile OS much faster and more fluid, so Google had their own work cut out for them. In fact, the statement is exactly along those lines: “the FlexyCore team has strong expertise in building software to optimize Android device performance, and we think they’d be a great fit with our team”. Right on.
