Now that a leaked build of Android 4.3 is in the wild, curious users have been poring over the code to see exactly what’s new. Kevin from TeslaCoil Software may have found one of the first real gems: there’s now a notification listening service under the hood. The feature would let third-party apps read notifications and perform common notification-level tasks. While we don’t have new software to show exactly how the service will work, it’s possible that future apps will have limited control over each other without relying on the hacks that we see today. We’ll know the full story when Google makes Android 4.3 official — whenever that is.
