Android 4.4 KitKat running on Rockchip domestic tablet device


After Google released Android 4.4 KitKat, many phones already upgrade their OS to this version, and the domestic tablet device is also ready to adopt this operating system and the domestic tablet device that uses Rockchip RK3026 dual core, manufacturers RK3188 quad-core chip solution, such as Lenovo, Toshiba, Asus, five elements, PIPO, is also ready to upgrade their system to upcoming Android 4.4 KitKat operating system.

Test platform:



One, full of feeling good

Compared to the previous Android system, the relatively large changes in 4.4. First, the status bar and virtual buttons into a transparent state, and to maintain a faint gradient effect. A place close to the border around the black edges designed background (very fine), the center gradually diverge transparent. Virtual button white vacuum, so beautiful and eye-catching mix. The default is three: back, home, task manager. Screenshot open in the settings themselves. I think this program has two advantages: ① reduce light leakage around the sense of the display, ② certain procedures to better vision without being blocked toolbar.


4.4 drawer, leaving only the icon of all programs, cancel the first two generations of the drawer? Actually no, but for a place only. Long press on the desktop, out of the secondary menu. Which include: the wall paper , small tools, settings.


Rather strange that not all settings set, but named “Search and sticky notes” of the project, specifically the four items pictured above. Another long press the desktop, but also to switch between desktops primary and secondary pages, easy management page.


In the unlock screen, retains the graphical unlock, face unlock, etc. and of course the most common slide to unlock. Android 4.2 touch sliding unlock wave does not change, there is a small tool to unlock the interface which can be customized. Whether or unlock the interface into the system can open the drop-down menu: Message Bar + set the bar.

We have seen, because it is testing the prototype, I think the system is also the initial commissioning, it is normal that some are not perfect. For example, the system language is English, after trying to find out is to adjust to Simplified Chinese, indicating that Android 4.4 is the inclusion of the Chinese package.


After adjusting for the very familiar look again relevant information. The version number is displayed rk30sdk-eng 4.4 …… prove that the firmware from Rockchip chip solution provider.

Second, the built-in domestic non-castrated complete Google+

Only one pre-installed software, I later added a pea pod, search dogs and other software, barely reached two, so the number is not that much. When installing pea pod is through data cable to connect pc, automatic safety up the middle will be prompted to first open usb debugging, allowing unknown programs and other “international practice” did agree to. Enter the pea pods in a little problem: Although Android 4.4 is included Chinese, Chinese can also be displayed, but only the English input method, therefore it downloaded Sogou input method.

Required “active” after the “Settings” for proper use.


Google+ will integrate Google’s online products as the basis for a complete social network. In order for service is different from Facebook, Google will bet on one aspect: better privacy management, which is the soft underbelly of Facebook; course, in the past, Google’s privacy but also weaknesses.
Google+ friends and acquaintances of the center point of the “circle (Circles)”, the user can organize contacts in different circles, such as family members, colleagues, university students, etc., and share photos in a small circle, video, and other information.


Comes with a google erth panoramic maps from the Earth began to zoom into specific locations. Recommended a number of Chinese tourist cities in the options, feel the general effect.

Third, the application of surprises and more personalized features a very avant-garde

Support low-power sensor support Pacer pedometer , exercise anytime, anywhere. 4.4 system in this regard is to spend some thought. I think this feature will definitely be more small-size tablet . I also tried it out of curiosity. Playing basketball together before a buddy child’s Tyrant gold basketball shoes can be docked, so after analyzing the data, such as: How many times jump, the highest number of cm, ran a number of meters, the number of calories consumed. After Android users can enjoy the same, and the use of very low threshold.


The system comes with a music player too times, only to achieve “out loud” requirement, so I downloaded every day sounds. Whether in the interface, EQ settings, be far better than the former sort finishing.


The most important is not the problem, Android 4.4 improved, increased lock screen album art display and playback controls. As the figure above, it becomes unlocked four directions, {after} the front left and right to control one, it controls the pause (play), so that in case it does not unlock the direct control of the music played.


Everyday sounds with dynamic replacement cover (album cover all wake up the screen every time replacement, even if the same song in a dynamic transformation), as well as the lyrics scroll, really beautiful and practical.


Four, Android office no longer tasteless

Picture browsing and playing the same songs, all with a lot of settings, edit. 4.4 added a new document processing software: Quickoffice. DTG commonly used than before on a more refined features, making it possible to commercially Android. Integrated interface contains WORD, EXCEL, PPT.


In the usual work and study, the use of the Android platform to better processing documents, spreadsheets, regardless of location space constraints. Into an additional 4.4 also supports wireless cloud print (documents, images, web pages) to add storage access framework functions, user management file.


In the camera, the 4.4 also made some fine-tuning. Panoramic photographs, video summed together. The shutter is a large round blue screen buttons, eye-catching and easy to operate. Advanced settings collections in the right shutter.

Another method to open the advanced settings are: single finger press the space in the camera interface. At this point the pop option, further sliding through the fingers, the direction of bias which option opens. There are location, countdown, picture size, shooting mode options.

The domestic flat, with a quad-core Rockchip RK3188 product, browse the web, as well as 1080P decoding playback, the effect is very smooth, rapid response.

Android 4.4 also made a multimedia optimization, support for screen recording capabilities, support for low-power audio processing, up to 60 hours of music playback time, improve 50% WiFi Display compatible Miracast certification. Regular pen by actual experience, the music playback time is indeed very impressive, compared with similar products in the past, fully raised several orders of magnitude, great power optimization.

V. Summary

In fact, the most fundamental optimized Android 4.4, that from now on be known as the world’s most fluent system, it can be as low as 512M of memory to run smoothly on the use of ART replace Dalvik, improve application speed. RenderScript computing optimization, enhance graphics rendering capability of 1.6 times.
