Android 4.3 expands on the execution enhancements effectively includes into Jelly Bean — vsync timing, triple buffering, lessened touch inertness, CPU input lift, and equipment quickened 2D rendering — and includes new development that make Android significantly speedier.
For an illustrations execution support, the equipment quickened 2D renderer now advances the surge of illustration summons, changing it into a more proficient GPU design by adjusting and consolidating draw activities. For multithreaded preparing, the renderer can likewise now utilize multithreading over numerous CPU centers to play out specific task.

For every gadget, you can check for upheld GATT benefits by UUID and oversee associations by gadget ID and flag quality. You can associate with a GATT server facilitated on the gadget and read or compose attributes, or enlist an audience to get notices at whatever point those qualities change.
This version introduces built-in support for VP8 encoding, available from structure and local APIs. For applications utilizing local APIs, the platform includes OpenMAX 1.1.2 augmentation headers to help VP8 profiles and levels. VP8 encoding support includes settings for target bitrate, rate control, outline rate, token apportioning, blunder flexibility, reproduction and circle channels. The stage API presents VP8 encoder bolster in a scope of arrangements, so you can exploit the best configuration for your substance.
VP8 encoding is accessible in programming on every single perfect gadget running Android 4.3. For most noteworthy execution, the stage additionally bolsters equipment quickened VP8 encoding on competent gadgets.
Applications can utilize new media muxer APIs to join rudimentary sound and video streams into a solitary yield document. At present applications would multiplex be able to a solitary MPEG-4 sound stream and a solitary MPEG-4 video stream into a solitary MPEG-4 yield record. The new APIs are a partner to the media demuxing APIs presented in Android 4.2.
Android 4.3 includes RTL execution improvements and more extensive RTL bolster crosswise over system UI gadgets, including ProgressBar/Spinner and ExpandableListView. Additional investigating data obvious through the uiautomatorviewer device. Furthermore, more framework UI segments are presently RTL mindful, for example, notices, route bar and the Action Bar.
To give a superior systemwide involvement in RTL contents, more default framework applications presently bolster RTL designs, including Launcher, Quick Settings, Phone, People, SetupWizard, Clock, Downloads, and then some.
The “4.3 is for wearables” theory clarified the moderately low number of features in 4.3: it was pushed out the way to give OEMs time to refresh gadgets in time for the dispatch of Android Wear. The task appears to have worked. Android Wear requires Android 4.3 and up, which has been out for so long now that most real leaders have updated.
