Android 6.0 Resolution - Fingerprint Scanning Identification Module Provides Native Support

The system combines a variety of consumer expectations of functions, including optional application permissions, data backup systems, and to Ext4 file system format SD card and so on.


When it comes to mobile operating system, Android is undoubtedly one of the best choices, this is the system used in many mobile devices finally began to push its latest version --6.0. The system is always a delicious dessert with its name, but this time - marshmallows (Marshmallow). Cute cotton candy will eventually appear on numerous smart phones, tablet computers, watches, television as well as cars and other kinds of products and equipment, let us take a closer view about it, take a look at Google to bring us what new, it is exciting new features now!

Google says this version will "return to nature", focus on improving the "quality" aspect. The system combines a variety of consumer expectations of functions, including optional application permissions, data backup systems, and to Ext4 file system format SD card and so on. In addition, 6.0 also USB Type-C power supply, fingerprint authentication and 4K ready, but also includes a new operating experience, for example, called "Google Now on Tap" context-based search mode.


In Android 4.4 KitKat inside, the search application to take over the entire main screen, ready to recognize voice commands. To 5.0 Lollipop inside, the search function to the provision of voice search service in the entire system level, users can trigger this feature on any screen.

This time, in the 6.0 version, the Google search has become ubiquitous, by the called "Google Now on Tap" a new feature, just press the home key, the current screen content will be transmitted to the Google search. Voice interactive interface also allows each application can use Google search service, so that third-party developers can easily integrate Google's search services with voice recognition engine.

The main screen as well as Google search


Google search application on the main screen has been redesigned, more prominent visual. Since the main application screen itself, so this change will be reflected in the previous Android system.

Applications in the organization has also been adjusted to help users locate the entry dazzling in that paragraph required, users can quickly browse through the first letter of an index, or search via the search box.

Press "application list" (app drawer) icon on the main screen you can jump directly to the search box.

Google Now on Tap


As new features in 6.0, here ready to spend more ink detail about the "Google Now on Tap". This feature is a means of Google to strengthen its existence in this open-source operating system and resorted to branding. Simply press the home key, and the current screen content associated information card will pop up. For example, if a user is viewing period by a video starring a star, then the card will display more information about this person.

Use this feature will allow Google to text and screenshots for reading information on the current screen, and the application can also use the "Now on Tap" achieve more. In the example above, one Movie website will be able to provide links to the actors from the film experience and other details of the link.

Click on the top card of the text or pictures directly triggered ordinary Google search process, click on the bottom of the associated application will result in a variety of different outcomes, depending on the contents of the current screen display, such as jump directly to the MV playback page, turn to social networking sites or pages related to someone's review site, and so forth.

As long as the contents of the current page is very specific, very targeted, for example, specific activities, schedule information or to someone or something, then the "Now on Tap" are generally able to help users find related information. This is the traditional keyword search different Google services need to speculate on the current topic. For example, if a user is viewing a particular place, then it may need is a map-related business hours, or phone number of classes. If the on-screen object is a person, you may want to learn more about this person's life, social or news accounts. Because unlike the usually precise search using the keyword as the clarity of the knowledge of the user's intent, the level of accuracy of this thanks to Google search or not the backend services.

"Now on Tap" pop-up message to the user in addition to the cards, you can also operate by voice command, that is, the user can ask questions related to the current screen contents, for example, "where far away from me?." If the user wants to find a place somewhere in particular, especially those places exist on review sites, Google searches are generally able to return accurate results of user expectations.

Considering this is a new function, in operation for some time after the accumulation, which will be able to become better.

Assist API (Application Programming Interface Auxiliary)


Google Now on Tap "is the" Assist API "can be achieved with the help of, developers can also take advantage of the programming interfaces to their applications. On openness and compatibility, the Android mobile operating system other than to be more Some are open, third-party developers are free to the numerous functions of the system by their own applications to be replaced. as this topic is too biased technical, interested readers can read the developer documentation on their own. Incidentally, Google voice search and interactive features also developed a corresponding API programming interface.

Application license


Android 6.0 provides a new permission system, users can refuse access to the system-specific part of the application. Now, the development framework 6.0 provides the functionality needed to request permission, and therefore the future without having to be installed when the application requires the user to decide everything.

Previous application permissions feature follows the Android 4.3 design ideas since, when an application is blocked for permission, the user did not know, and this may make the application of some of the features do not work, even when severe can cause the application to crash , but users do not know where exactly is the problem. The Android 6.0 permissions system allows developers and users of the applications require specific permission to be able to clearly understand the project. Therefore, the application will not be a specific permission is prohibited on the crash, and the user of a decision on their own can get more information. Thus, even in preventing one or some privileges, the whole application problems, the user clearly know the root cause of the problem.

With a new way to develop applications during the installation no longer ask permission options specific to the user, but in the next run time, when the need to use a particular function, and then ask each user. Decided in the dialog box, allowed only to make a decision, and rejected permanent need only be made in the second, effectively avoid the trouble caused due to wrong decisions. Of course, even if you change your mind, you can still adjust the permissions directly, just the process just a little trouble.

Fingerprint API (application programming interface fingerprint)


Fingerprint scan authentication function appears on several Android smartphones too, but related modules and solutions from third-party vendors, Android kernel or system level rather than direct support of the product. Google clearly see the development trend of related technologies, therefore, provides the official 6.0 API from Google's fingerprint. Incidentally, Apple provides a similar API for their TouchID fingerprint reader module.

That is to say, from 6.0, developers can integrate fingerprint sensor directly into their applications and associated user interface elements complete control. Google To ensure the consistency of user experience, but also provide the relevant icon to choose from.

In addition, the 6.0 also provides a so-called "Confirm credentials" (Confirm Credential) of the API, for lock screen reconfirmed control device to ensure that the equipment is still rests in the hands of real users.

Automatic Backup


Although Android since version 2.2 begins by providing some sort of backup service, but has not been to provide comprehensive backup program. Many developers have completed additional work, but in the eyes of users, Android backup service is nothing more than the application that will be installed in one place, when you reinstall it again in the future restored, a full backup of the user's personal data protection will not suffer.

Android 6.0 provides a so-called "automatic backup" of the new service, you can back up any data. Since the system was just released, is still unable to obtain the actual test results, but in theory, all the user data of the service will use the data directory to save to the cloud when you need to recover in the future, only the user through the login process you can use and, therefore, no need to re-view the splash screen when the application is first run, and a variety of cumbersome content settings.

Automatic backup service runs once every 24 hours, is triggered in the device plugged charging plug, idle and there is Wi-Fi connection. The data will be encrypted and stored on Google Drive service.

Act as an external memory card internal storage space


Android 6.0 provides a so-called "adoptable storage" of new features designed to provide local support for the expansion of the memory card, memory card system for such re-formatted before it was treated as an internal storage space.

Previously, Andrews will be regarded as external SD card storage space, although Froyo version, users can apply to move to SD card, but private application data must be stored in the internal memory space, only a few such applications like camera allows users to Select the data storage destination, and complicated steps.

It should be noted that, if the user decides to SD card as an internal storage space usage, the card can not be arbitrarily removed from the Android device, the system uses the Ext4 file system to format the card, rather than the traditional VFAT, and the use of 128 bit AES encryption. In addition, before the operation, Andrew system will speed SD card reader for testing, if you do not meet the requirements, will be given the appropriate reminder. There is, if for various reasons, the user has to remove the SD card, then the previously stored therein data will be permanently lost.

While Android 5.0 provides a file manager, but only as a download management purposes. In 6.0, the File Manager features to enrich a lot, enough to cover the entire storage system, users can delete, copy, or "shared" files with other applications, but the "cut" and "Rename" This type of function is not available.

Direct share


Andrews system "share" menu allows users to share among various types of data, including photos, links, and location. 6.0 provides a so-called "direct share" (Direct Share) of the new features, after the user clicks shared contact list will pop up directly to further simplify the previous steps.

Volume and notification


In Android 6.0, volume control panel has been greatly simplified, version 5.1 of the "priority notice" control is moved to the Quick Setup panel, leaving only a single volume adjustment control. Touch the small arrow will appear to the right of three specific volume control: notification, media, and alarm clock.

In 6.0 there is an acclaimed changes, that is: users can now set up notification forms separately and priority level for each application. Previously, developers can decide important level notice that there will always be some nasty news suddenly appears at the top of the screen. In 6.0, users have the right to decide whether to display the content.

Prior to version 6.0 not only control layout has been adjusted, but also about the notification, voice and DND introduced a number of rules, and interested readers can self-refer to the relevant article, limited space, not repeat them here.

Doze mode

When in idle state, the power consumption is much larger than iOS device Android device, Google hopes to "Doze" (sleepy) mode to alleviate this situation, it makes almost no connection device enters a low-power mode.

Andrews systems not only through the screen status to determine whether the device is in use, but also by an accelerometer to determine whether the device is in motion, in order to decide whether to enter the "sleepy" modes. This means that this mode only when the device is placed on the desktop will still enter, but when it is not in the pocket.

Once in the "sleepy" mode, network access will be disabled, the system will no longer accept any background processing requests, alerts, and scheduled tasks of various system will also be closed, substantially all of the background tasks will be stopped, very similar to the common Flight mode.

Applications standby

Unscrupulous operators and mobile phone manufacturers is the source of all kinds of junk software, which takes up the phone useless software in addition to processing resources, electricity consumption, there may have a variety of data traffic. "Apply Standby" (App Standby) feature is designed for the software and set up, if the application within a certain period of time has not been used, it would be converted into a standby mode, you can not access the network, but also unable to perform synchronization tasks, basically it is quite in the prohibited state.


As for what is "is not used within a certain period of time", "Apply standby" feature is turned on by the user application, whether as a front desk run or invoked by other applications as well as to determine whether to generate a notification. If the application does not generate the above acts, it is likely to be identified as requiring standby mode.

There is a so-called "battery optimized" place in the battery settings screen, where the user can exclude specific application potential standby application list, but just tap the application name and then select "Do not optimize" button.

This feature is useful for those who refuse the software can not be deleted. Now, even if the user is not familiar with the system works the way technology house, Andrews will automatically switch off these things surreptitiously run in the background by the above logic, to prevent additional power consumption.

Text selection

Highlight the text effect in the Android 6.0 has been improved the standard "Cut", "Copy" and "Paste" Control is now organized in a floating toolbar appears in the top of the selected text. And by "sharing" operation, the user can export the selected text to another application.


Text selected action has also been improved to some extent. Now, moving forward the teardrop-shaped control will select the entire text fragments, and backward dragging revocation letters will be individually selected.

Chrome custom tab

In daily operations, they usually need to turn the page, and by Android Chrome comes to complete is undoubtedly the best choice. And if it is through the application of open, since Chrome will render pages as a standalone application, then the transaction complicated today, users can easily forget to return to the original application, the application will easily lose user stickiness.


Previously, developers through the use of a so-called "WebView" control to solve such problems. WebView is based on the Chromium developed Web rendering engine that can be embedded into the application use, and the drawbacks of using this program is unable to take advantage of Chrome's various convenience and synchronization capability. Android developers in order to dispel the concerns, launched a Chrome custom tabs to replace the widely used before WebView.

Chrome custom tab does not address bar, press Back to return the application screen, which is capable of seamless cooperation with a variety of applications, and more WebView or Chrome to open the page much faster speed. Because of this program completely based on Chrome, such as auto-complete, cookie, cache and permissions Chrome have been intact. Users do not need to repeat the same login once logged sites, various text boxes and form fields will be automatically populated.

Android for Work


Android for Work is a series of policies in office occasions Android devices developed so that business users can be properly controlled. In a similar office equipment such occasion comes at Android for Work with the help of the device can distinguish between work or personal use on the privileges and storage space. Users will still face a single main screen interface, but the presence of two copies of a single application would, strictly separated from each other. Corporate IT departments can remotely erase data office use, but the relevant data personal side intact. For more information on this aspect, the reader may consult the relevant documentation to be understood that the limited space, no longer expand.

Other

In addition to the fingerprint reader module on the new Nexus, Android 6.0 also provides support for a variety of hardware, such as connectors without the need to distinguish between positive and negative direction of the USB Type-C as well as a new USB-powered Android M specification.


Life, the Android 6.0 and Android 5.1.1 performance is almost the same. Of course, this is a result of constant light on the screen and stop loading the page until the battery runs out tests to get. Once enabled, "sleepy" modes, Android 6.0 will no doubt significantly extend battery life.

Android 6.0 even offers support for MIDI devices, which makes a device equipped with the system in some of the user's hand flew to morph into a music creation tool, simply connect the keyboard to start the creative process.

The system also supports Bluetooth active stylus, compatible hardware products in the pairing can send pressure and key state data, and then combined with touch screen input. As a result, other manufacturers seem to have found an opportunity with the Samsung Galaxy Note under a high.

Android 6.0 also provides a new flashlight development interface, developers do not need to route through the camera API to activate the flash. In previous versions of the Android system, flashlight and camera can not be used simultaneously, and now, with the help of the system, the seamless transition between the two can be.

The system uses Google's own BoringSSL replaced the previous OpenSSL, which is subject to Heartbleed vulnerability widespread. Although Google launched a number of patches for OpenSSL, but due to the backward compatibility issues, can not be widely adopted by the industry, which Google turned to their BoringSSL to never troubles.

Summary

In the latest Android system, Google will more discretion hands of the user, so that the latter decide what applications can do and can not do, but also allow the user to see the release of a particular permission is prohibited and accompanying consequences. In addition, let the user decide what and when to turn off the notification should be closed is not a small step forward.


The introduction of "sleepy" modes will greatly improve the life time Android devices, and "application standby" function is one solution to the various types of junk filled Android devices ills.

The system scans the fingerprint identification module to provide native support API level, I believe that such capabilities will soon become standard Android device.

Currently, the biggest ills lies in updating Android. Even Nexus users receive updates unusually slow speed, but better than nothing, the other device you want to update to the latest Android 6.0 marshmallow is nowhere in sight. Perhaps a similar Windows Update as centralized updating system to solve such problems.
