Google’s Android N developer preview introduces support for running multiple apps simultaneously, an enhanced Quick Settings panel, and much more.
One thing I’m particularly looking forward to? It takes less time to upgrade to Android N or apply any system updates.
That’s because Android N changes the “optimizing apps” portion of the upgrade process.
Android used to use a just-in-time compiler, but when Google introduced Android 5.0 Lollipop, the company moved from just-in-time (JIT) to ahead-of-time (AOT). That led to improved performance when you actually wanted to run your apps… but it meant that every time you applied a system update, you might have to wait a 5-20 minutes for Android to compile apps before you could start using your phone again.
Android N uses a blend of the two methods. There’s a new JIT compiler with code profiling for improving app performance while you run them.
The AOT compiler is still there for pre-compiling and caching certain components of each app, but other parts are only compiled when they’re used.
Google says this should offer the best of both worlds: apps run more quickly and efficiently, but system updates and new app installs can be finished in seconds instead of minutes.
