Yesterday Hugo Barra has just officially unveiled the new
Nexus 7, first device to be marketed directly with Android 4.3 Jelly Bean ,
expected distribution that brings with it many new features that we will deepen
in the course of this article. The great news is that the update will be
available from today for all the latest components of the gama Nexus, Galaxy
Nexus and Nexus 4 smartphone from up to Nexus 10 and Nexus 7 first generation .
What's new in Android 4.3 are numerous and as anticipated
promise to bring the experience to a higher level of use of Jelly Bean. Let's
see in detail what are the points of interest on which Google has decided to
work.
System faster and smoother
Progress Software are manifold, Android 4.3 has vsync timing , triple buffering, latency time of the touch
reduced CPU input boost acceleration and 2D hardware , the latter able to take
advantage of the GPU and manage multithreading between the different Core. The
best graphics performance are also due to library support OpenGL ES 3.0 , hardware-accelerated effects
and visuals never seen until now.
Bluetooth Smart Ready
With Android 4.3 you will have full support for Bluetooth
Smart Ready , with new APIs available to developers which will allow you to
connect to many mobile devices, interacting with them in a completely different
way. Support for this new 'platform' is already in place on the new Nexus 7 and
Nexus 4, as well as many other Android devices that will soon hit the market.
The new standard also adds support for Bluetooth AVRCP 1.3 , a new protocol through
which the App will be able to interact better streaming and other similar
operations.
Profiles Reserved
With the new distribution Jelly Bean has been further
improved its multi-user capability dedicated to the tablet , as in the past it
is possible to manage different profiles on the same device, but with a level
of privacy and separation even stronger . Nexus 7, Nexus 10 and the next device
that will integrate Android 4.3 may be used by different users, having the
utmost discretion: in fact enjoy every account of their home screens, widgets,
and local storage settings .
It will be impossible to access the administrator profile
from others specifically created a physical separation that many will
appreciate. Obviously, the administrator can also disable the operation of
certain applications on the other profiles, limiting the use according to the
needs.
Sensors and Wi-Fi
Google Play Services provides advanced location API that can be used in
applications that require geo-referencing. With Android 4.3 these APIs have
been further improved, taking advantage of the hardware with respect to energy
consumption: Wi-Fi-only scan is such a new mode by which you can improve the
geolocation of the device to a network without being physically via Wi-Fi, with
a substantial saving of resources. This functionality is not dependent on the
hardware, it is a software that is part of Android 4.3 .
Among the new sensors have supported the game rotation vector , to better manage the
rotation of the device without having to worry about interference (primarily
useful for development). Among the new we also
gyroscope sRGB and un-calibrated magnetometer , both available
on the new Nexus and Nexus 7 4.
With the new version of Android is now possible to connect
to access point with WPA2 enterprise . Developers can then use for
their own App stricter standards and new APIs to support the Extensible
Authentication Protocol (EAP) and Encapsulated EAP (Phase 2).
GPU
Developers will have an easier time with Android 4.3, with
the ability to easily analyze the performance of App Through the function Profile GPU rendering so you can view the
actual frame rate applications, during their execution, a kind of overlay on-
screen that makes it easy and immediate. Each color corresponds to the input
and responses of the software, with a green bar that marks the ideal of 60ms.
These are the main changes in the new Google distribution,
in the coming hours we will definitely able to test directly the progress using
Android 4.3 and all the new features.
