Google announced through a blog post that developers can develop application against the API level 16 using the new Jelly Bean APIs.
Nick Butcher, a Google engineer, wrote, "You can now develop and publish applications against API level 16 using new Jelly Bean APIs."
Developers would be able to develop apps that will run on Nexus 7 tablets. Jelly Bean is touted as one of the best from Google and it promises a smoother and more responsive UI across the system. Android 4.1 also brings with it triple buffering in the graphics pipeline that will enable consistent rendering and a more synchronized touch to reduce latency. The home screen has been completely revamped and will automatically adapt to fit the content. It also features Google Now that will bring personalized information like local weather and traffic updates.
Some of the new features in the developer API are expandable notifications that bring in larger, richer user alerts; Android Beam for simplified Bluetooth-based data transfer; bi-directional text support; accessibility services; low-level access to platform hardware; low-level access to software codecs; network bandwidth management tools including tethering to a mobile hotspot among others.
Jelly Bean is also considered to be Android's most secure version.
