What are the new features, new functions and different designs of Android 4 3 that are worth talking

Personally, I think it's worth mentioning is the support for Bluetooth Low Energy.

New: 1. When browsing the album**, the shooting location will be displayed at the same time (if the camera has enabled the recording geotag).

2. The system is smoother, and the speed of the camera autofocus is accelerated.

3. Take photos in HDR mode, and the processing speed becomes faster after shooting.

System: 1. It is more power-saving.

2. For the positioning part, if the positioning function (location) is turned off and then turned on, it will become impossible to locate in Google Maps.

In an application, an activity is equivalent to a mobile phone screen, which is a component that can contain a user interface and is mainly used to interact with the user. An application can contain many activities, such as clicks on events, which generally trigger a new activity.

Apps can use it to filter external events and receive and respond only to external events of interest, such as when a call comes in, or when a data network is available. Broadcast receivers do not have a user interface. However, they can launch an activity or serice in response to the messages they receive, or use a NotificationManager to notify the user.

Notifications can grab the user's attention in many ways with flashing backlights, vibrations, sounds, etc. Generally speaking, it is to put a persistent icon on the status bar that the user can open and get the message.

Content providers are mainly used to implement the function of data sharing between different applications, and it provides a complete set of mechanisms that allow one program to access the data in another program, while also ensuring the security of the data being accessed. Content providers are only needed when data needs to be shared across multiple applications. For example:

Contacts data is used by multiple applications and must be stored in a single content provider. The benefit: Unified access to data.

It is a solution for Android to implement the background running of the program, which is very suitable for performing tasks that do not need to interact with the user and have to run for a long time (while playing **, QQ is hanging in the background). The operation of the service is not dependent on any user interface, even if the program is switched to the background, or if the user opens another application, the service will remain functional, but the service does not run in a separate process, but depends on the application process in which the service was created. When an application process is killed, all services that depend on that process also stop running (listening, then quitting the program).

1. New material design style.

Android Lollipop's new design language is influenced by a variety of factors, and it is a bold flat innovation. In other words, Google wants to make Material Design a paper-based experience for users. The new visual language, in the treatment of basic elements, draws on the traditional printing design, font layout, grid system, space, proportion, color matching, image use and other basic graphic design specifications.

2.Supports a wide range of devices.

Now whether it is a smartphone, tablet, laptop, smart TV, car, smart watch or even various home electronics, Google's Android system can already appear on the screen of all devices.

3. Brand new notification center design.

Google has added a new style of notification system to Android Lollipop. The revamped notification system prioritizes information that's important to users and hides less urgent content. Users only need to swipe down to see the full content of the notification.

Another cool new feature of the new notification system is that you can also view notification messages directly on the lock screen. Not only that, but users can also reply or enter the app directly with the screen locked. In addition, if there is ** entry in the process of operating the mobile phone, it will not switch to the full screen, but also inform the user in the form of a pop-up notification.

4. Support 64-bit ART virtual machine.

5. Project Volta battery life improvement plan.

6. Brand new "Recent Apps".

7. Improve security.

8. Different data are stored independently.

10. New API support, Bluetooth audio, multi-person sharing and other features.

Android vs. Summary.

Interface Comparison: This part of the comparison is only for the UI interface between Android and (in other tests for functionality). In the current operating system, including Windows Phone and Apple iOS, the adjustment of the UI interface before and after the version upgrade will not be "drastic" to modify, and the pursuit of deliberate changes, especially in the transformation of the main color, in order to maintain its own unique classic interface and inherit its own style mode.

Between the two versions of Android, the style continues, with only a few minor modifications and changes.

Operation experience: Added some user-friendly features, such as the automatic arrangement of desktop icons, and the "tapping" icon to delete the icon operation. Compared with Android, the experience has been improved, but the few shortcuts at present are obviously not comprehensive enough, which is very much looking forward to Android in the next update, continue to "add bricks".

Notification Center: I believe that Android veterans should be very familiar with the various notification behaviors of Notification Center. The Android upgrade, on the basis, adds three one-click quick start functions.

These changes in detail compared to the system really improve the efficiency of users to use the phone quickly.

Voice feature: This is an important upgrade feature for Jelly Bean Android. Google New, offline voice keyboard, etc., are all built on the basis of voice functions, and the functions are upgraded.

After this upgrade, the user's voice keyboard input method under airplane mode is satisfied.

Flash support: Flash for the Android system, the role played by the role is actually "the end of life", the effect is far from the excellent performance of the traditional PC system. We are here to draw out a single test,Just to illustrate,Android will inevitably choose another support to join after letting go of flash support,So what will this support be?

That's HTML5, and we'll see how Android will perform on HTML5.
