Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Among them, in the description of the embodiments of the present application, unless otherwise specified, "/" means or, for example, A/B can mean A or B; "and/or" in this document is only a description of related objects The association relationship of indicates that there can be three kinds of relationships, for example, A and/or B, which can indicate: A alone exists, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "plurality" refers to two or more than two.

The mobile terminal described in this application may include mobile phones, tablet computers, wearable devices (for example, watches, bracelets, smart helmets, etc.), vehicle-mounted devices, smart home devices, augmented reality (AR)/virtual reality ( virtual reality (VR) equipment, notebook computers, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (personal digital assistants, PDAs), etc. Some embodiments of the present application take a mobile phone as an example, and it should be understood that these embodiments can also be applied to other types of mobile terminals.

手机，第三方应用可以是除了华为以外的其他开发者开发的应用。 The application program (application, app) involved in this application may be referred to as an application, which is a software program that can realize one or more specific functions. Generally, multiple applications can be installed in a mobile terminal, for example, sports applications, music applications, dictionary applications, and so on. It is understandable that the application may be an application that has been installed when the mobile terminal is shipped from the factory, or an application that the user downloads from the network or obtains from other electronic devices in the process of using the mobile terminal. Third-party applications usually refer to applications developed by non-mobile terminal manufacturers. For example, for Huawei

For mobile phones, third-party applications can be applications developed by developers other than Huawei.

For security, privacy, or aesthetic considerations, the mobile terminal can be set with a lock screen, and the functions of the mobile terminal can be used normally after unlocking the set lock screen. Otherwise, it cannot be used or only a part of the functions can be used. For example, if a lock screen is set, when the phone screen is turned on, an unlock interface will be provided, and the user needs to enter a password to unlock before entering the user interface for normal operations. The mobile terminal can be set with a variety of lock screen methods, which can generally be divided into system lock screen and third-party lock screen. The system lock screen is the lock screen provided by the mobile terminal system itself, and the third-party lock screen is a third-party application installed on the mobile terminal. Provide the lock screen. Among them, the system lock screen can include security lock screen and non-secure lock screen. The so-called security lock screen can be pattern lock screen, digital lock screen, gesture lock screen, fingerprint lock screen, face lock screen, voiceprint unlock or hybrid Password lock screen (such as a combination of numbers and letters), has the ability to verify user identity, usually only users who know the password (authorized users) can unlock; non-secure lock screen, generally set for non-secure reasons such as beauty , Does not have the ability to verify user identity, and unauthorized users can also unlock it. For example, the magazine lock screen is a common non-secure lock screen, which presents a wallpaper like a magazine cover on the phone screen. Every user, including authorized users and unauthorized users, can unlock the non-secure lock screen according to the unlock prompt. In this case, the unlocking method is generally relatively simple, such as tapping the screen, sliding the finger (which can be sliding left, sliding right, sliding up, sliding down, sliding diagonally, etc.). Users can set different lock screen methods and combinations according to their own needs. For example, users can set secure lock screen, non-secure lock screen, third-party lock screen at the same time, can also set secure lock screen and third-party lock screen, or set non-secure lock screen. Security lock screen and third-party lock screen, you can also set up only third-party lock screen.

The third-party lock screen is generally overlaid on the system lock screen, that is, the system lock screen can only be unlocked after the third-party lock screen is unlocked. In some cases, the unlocking method of the third-party application lock screen is relatively simple, such as tapping the screen, sliding your finger (which can be left, right, up, down, diagonally, etc.) to unlock. Usually authorized users and non-users Authorized users can unlock the screen; it is understandable that the lock screen of some third-party applications requires a password. Only authorized users can unlock the screen. The unlocking method can be similar to the system security lock screen, such as unlocking with a pattern or password. Therefore, this application does not limit the unlocking method of the third-party lock screen. Third-party applications, such as music applications, sports applications, dictionary applications, etc., can provide a lock screen interface. For example, the third-party lock screen provided by the music application shown in Figure 1A can display the music being played or previously played, including the music name, lyrics, music album cover, etc., and can also provide some function buttons, such as pause, play, and upload. One song, next song, volume, playback mode, favorite buttons, playback progress bar, etc., so as to facilitate user operations. For another example, the third-party lock screen provided by the sports application shown in Figure 1B can provide sports-related information, such as exercise duration, exercise distance, exercise type (running, car, swimming, etc.), heart rate, calories consumed by exercise, etc. Some function buttons can also be provided, such as pause exercise, stop exercise, switch exercise type, etc. For another example, the third-party lock screen provided by the dictionary application shown in FIG. 1C can provide a word query input box, or sequentially play words, phonetic symbols, or paraphrases in the user's favorite word book.

Currently, if there are multiple third-party applications that provide multiple third-party lock screens, you need to unlock all third-party lock screens in turn before you can unlock the system lock screen (if the system lock screen is set), or enter the user interface ( If the system lock screen is not set). Moreover, different third-party lock screens have different unlocking methods. For example, some are swiping up to unlock, and some are enjoying swiping to unlock, which is cumbersome to operate and affects user experience.

It is understandable that the positioning device 108 may specifically be a receiver of a positioning system such as a Global Positioning System (GPS), Beidou satellite navigation system, or Russian GLONASS. After receiving the geographic location sent by the above-mentioned positioning system, the positioning device 108 sends the information to the processor 101 for processing, or sends the information to the memory 103 for storage. In some other embodiments, the positioning device 108 may also be a receiver of an assisted global satellite positioning system (AGPS). The AGPS system assists the positioning device 108 to complete ranging and positioning services by acting as an auxiliary server. In this case The auxiliary positioning server communicates with the positioning device 108 (ie GPS receiver) of the mobile phone 100 via a wireless communication network to provide positioning assistance. In some other embodiments, the positioning device 108 may also be a Wi-Fi access point-based positioning technology. Since every Wi-Fi access point has a globally unique MAC address, electronic devices can scan and collect the broadcast signals of surrounding Wi-Fi access points when Wi-Fi is turned on, so they can obtain Wi-Fi. -The MAC address broadcasted by the Fi access point; the electronic device sends the data (such as MAC address) that can identify the Wi-Fi access point to the location server through the wireless communication network, and the location server retrieves each Wi-Fi access The geographic location of the entry point is combined with the strength of the Wi-Fi broadcast signal to calculate the geographic location of the electronic device and send it to the positioning device 108 of the electronic device.

The audio circuit 109, the speaker 113, and the microphone 114 can provide an audio interface between the user and the mobile phone 100. The audio circuit 109 can transmit the electric signal after the conversion of the received audio data to the speaker 113, which is converted into a sound signal by the speaker 113 for output; on the other hand, the microphone 114 converts the collected sound signal into an electric signal, and the audio circuit 109 After being received, the audio data is converted into audio data, and then the audio data is output to the RF circuit 102 for transmission to, for example, another mobile phone, or the audio data is output to the memory 103 for further processing.

The peripheral interface 110 is used to provide various interfaces for external input/output devices (such as a keyboard, a mouse, an external display, an external memory, a user identification module card, etc.). For example, it is connected to a mouse through a universal serial bus (USB) interface, and is connected to a subscriber identity module card (SIM) card provided by a telecommunication operator through a metal contact on a subscriber identity module card slot.

The function library layer also includes other function libraries for implementing various functions of Android operating system phones, such as: SGL (Scalable Graphics Library): 2D graphics and image processing engine based on XML (Extensible Markup Language) files; SSL (Secure Sockets Layer) ): Located between the TVP/IP protocol (TransmissionControlProtocol/InternetProtocol, Transmission Control Protocol/Internet Protocol) and various application layer protocols, providing support for data communication; OpenGL/ES: 3D effect support; SQLite: relational database engine ; Webkit: Web browser engine; FreeType: Bitmap and Vector font support; etc.

Android Runtime is a running environment on the Android operating system, and a new virtual machine used by the Android operating system. In Android Runtime, using AOT (Ahead-Of-Time) technology, when an application is installed for the first time, the bytecode of the application will be pre-compiled into machine code, making the program a real local application. After running it again, the compilation step is omitted, and the startup and execution will become faster.

In some other cases, Android Runtime can also be replaced by Core Libraries and Dalvik Virtual Machine. The core function library provides most of the functions in the Java language API (Application Programming Interface), and provides an interface to the application framework layer to call the underlying library through the JNI (Java Native Interface) method. It also contains some core APIs of Android, such as android.os, android.net, android.media and so on. The Dalvik virtual machine uses a JIT (Just-in-Time) runtime compilation mechanism. Every time a process is started, the virtual machine needs to recompile the bytecode in the background, which will have a certain impact on the startup speed. Every Android application runs in an instance in a Dalvik virtual machine, and each Dalvik virtual machine instance is an independent process space. The Dalvik virtual machine is designed to efficiently run multiple virtual machines on one device. The executable file format of the Dalvik virtual machine is .dex. The dex format is a compression format designed for Dalvik, suitable for systems with limited memory and processor speed. What needs to be mentioned is that the Dalvik virtual machine relies on the Linux kernel to provide basic functions (threads, low-level memory management). It is understandable that Android Runtime and Dalvik belong to different types of virtual machines, and those skilled in the art can choose different forms of virtual machines in different situations.

4. Linux kernel layer:

Android's core system services, such as security, memory management, process management, network protocol stack, and driver model, are all based on the Linux kernel. The Linux kernel also serves as an abstraction layer between the hardware and software stacks. This layer has many drivers related to mobile devices. The main drivers are: Display Driver: Linux-based Frame Buffer driver. Keyboard Driver (KeyBoard Driver): As the keyboard driver of the input device. Flash driver (Flash Memory Driver): Flash driver based on MTD (memory technology device). Camera Driver: A commonly used Linux-based v4l2 (Video for Linux) driver. Audio Driver: A commonly used advanced Linux sound system driver based on ALSA (Advanced Linux Sound Architecture). Bluetooth Driver: Wireless transmission technology based on IEEE 802.15.1 standard. WiFi Drive: A driver based on the IEEE 802.11 standard. Binder (IPC) driver: A special driver for Android that has a separate device node and provides the function of inter-process communication. Power Management: For example, battery power, etc.

In the Android system, the WMS (Window Manager Service) service located in the application framework layer can be used to manage all windows, including the creation, deletion, and modification of windows, as well as the size, level, and focus position of the windows. The application adds and deletes windows in the Activity. The specific implementation is to call the addView() and removeView() functions of the WindowManager class, then call the related methods of the ViewRoot class, and then use the IPC to call the related methods in the WMS to complete the addition, Deletion process.

WindowManager.LayoutParams is a nested class of WindowManager interface; it inherits from ViewGroup.LayoutParams; it is used to describe Window management strategy to WindowManager. The attribute parameters (layoutParams) of the window may include type (window type) and flag (processing parameters for the window). The type (type) of the window can be divided into Application Window, System Window, Sub Window. When a process applies for a Window from WMS, it needs to tell the system the type of window. For Window display, the higher the level, the more front the display. Common window flags are: FLAG_KEEP_SCREEN_ON: the screen is always on; FLAG_SHOW_WHEN_LOCKED: when the screen is locked, the page is displayed; FLAG_DISMISS_KEYGUARD: unlocks without a password; FLAG_TURN_SCREEN_ON: lights the screen; FLAG_FULLSCREEN: full screen, no status bar; The window cannot be screenshotted; FLAG_SCALED: adjust the window as required by the user; FLAG_DIM_BEHIND: everything behind the window will be darkened; etc.

In order to achieve the purpose of quick unlocking, this application can use the following methods to manage the lock screen window:

When each application starts, WMS recognizes whether the window properties of the application carry the following flag: WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED. If there is this flag, it means that the window interface is a lock screen interface. This flag enables the window to be displayed on the lock screen when the screen is locked. It can be used with flags such as FLAG_KEEP_SCREEN_ON (keep the screen always on) and FLAG_DISMISS_KEYGUARD (unlock the screen).

For example, you can use the following code to add the properties of a third-party lock screen window to the Activity Window:

After identifying that the window provided by the system or application is a lock screen window, you can create a lock screen window stack in WMS, and add the identified lock screen windows to the lock screen window stack one by one. For example, if there are multiple third-party lock screens provided by multiple third-party applications, you can add these third-party lock screens one by one to the lock screen window stack for unified management. In the same way, the system lock screen window can also be added to the lock screen window stack and managed together with the third-party lock screen. It is understandable that the lock screen managed in the lock screen window stack can still distinguish the system lock screen and the third-party lock screen. The lock screen window stack may only have the system lock screen, or only the third-party lock screen, or both the system lock screen and the third-party lock screen.

After receiving the unlocking instruction, the system manages the multiple lock screen windows managed in the lock screen window stack, for example, unlocks according to a preset rule. If you want to unlock a certain lock screen, WMS can remove the corresponding lock screen window interface from the lock screen window stack.

Figure 4 provides a method for unlocking the lock screen. The method includes the following steps:

401: The mobile terminal receives a first unlocking instruction for unlocking the first lock screen, and the mobile terminal is provided with a first lock screen provided by a first application and a second lock screen provided by a second application.

The first application and the second application are installed on the mobile terminal. The two applications may both be third-party applications, or both may be system applications, or one may be a third-party application and the other may be a system application. These two applications can be built in the mobile terminal when it leaves the factory, or can be installed by the user during use. The first application may provide the first lock screen. For example, the music application provides a music lock screen interface as shown in FIG. 1A. When the screen of the mobile terminal is lit by the user, the music lock screen interface needs to be unlocked. Optionally, the music lock screen interface may display an unlocking prompt, for example, slide the finger to the right to unlock; at this time, when the user's finger slides to the right on the screen, the music lock screen interface can be unlocked. The specific principle of unlocking depends on the settings of the operating system. For example, for a mobile phone with an Android system, the unlocking principle is as described above, which can be that WMS removes the music lock screen window interface from the lock screen window stack.

It is understandable that the unlocking method of unlocking the first lock screen depends on the setting of the first application. For example, the first application sets the unlocking instruction of the first lock screen to be unlocked by sliding the finger to the right. Optionally, the user can also customize the unlocking method of the first lock screen. For example, the user can change the default unlocking method of the first application, for example, set it to be unlocked by tapping with a finger. As mentioned earlier, the unlocking method can include tapping the screen, swiping your fingers (which can be left, right, up, down, diagonally, etc.), and can also include using patterns, numbers, gestures, fingerprints, faces, Voiceprint or mixed password to unlock, you can also use physical or virtual keys and their combination to unlock, etc., there is no restriction here. The unlocking methods of the first lock screen and the second lock screen may be the same or different. For example, the second application is a sports application, and the second lock screen provided is as shown in FIG. 1B, and the unlocking method is to slide the finger upwards. For mobile phones with Android system, WMS can add the first lock screen and the second lock screen to the lock screen window stack one by one. There is no restriction on the time sequence of joining. The order of joining the lock screen window stack can be arranged according to the order of application startup or the order of the last operation. For the first lock screen and the second lock screen that have been set, the mobile terminal may receive a user's first unlock instruction, and the first unlock instruction is used to unlock the first lock screen. It is understandable that the first unlocking instruction complies with the unlocking mode set by the first application. For example, for the aforementioned music lock screen, the first unlocking instruction may be that the user's finger slides to the right on the screen.

402: The mobile terminal unlocks the first lock screen and the second lock screen.

After receiving the first unlocking instruction for unlocking the first lock screen, the mobile terminal unlocks the first lock screen and the second lock screen. It is worth noting that although the first unlocking instruction is for the first lock screen, it also unlocks the second lock screen. Although the unlocking manner of the second lock screen may be different from the unlocking manner of the first lock screen, the first unlock instruction can also unlock the second lock screen. When the unlocking method of the second lock screen is the same as the unlocking method of the first lock screen, the first unlock command can also unlock the second lock screen, that is, one unlock command unlocks two lock screen interfaces. Optionally, the first lock screen can be overlaid on the second lock screen. At this time, after the first lock screen is unlocked, the second lock screen is also unlocked; it can also be the second lock screen on top of the first lock screen. The user does not follow the unlocking method of the second lock screen, but sends an unlocking instruction according to the unlocking method of the first lock screen. The unlocking instruction "passes through" the second lock screen to unlock the first lock screen and unlock the second lock at the same time Screen. On Android phones, it can be that WMS removes the first lock screen and the second lock screen from the lock screen window stack.

After unlocking the first lock screen and the second lock screen, you can directly enter the first application or display the system desktop. There is no restriction here.

Through the above method, multiple third-party lock screens can be easily unlocked without requiring the user to unlock each third-party lock screen one by one, which improves the user experience.

Figure 5 provides another method of unlocking the lock screen, including the following steps:

501: The mobile terminal receives a first unlocking instruction to unlock the first lock screen, and the mobile terminal is provided with a first lock screen provided by a first application, a second lock screen provided by a second application, and a third lock screen provided by a third application .

For example, the third application may be a dictionary application, and the third lock screen may be as shown in FIG. 1C. The unlocking method of the third lock screen may be to unlock by sliding a finger to the left. It is understandable that the unlocking methods of the first lock screen, the second lock screen, and the third lock screen may be all the same, all different, or two of them are the same and the other is different. For mobile phones with Android system, WMS can add the first lock screen, the second lock screen, and the third lock screen to the lock screen window stack one by one. Optionally, the first lock screen may be overlaid on the second lock screen and the third lock screen.

502: The mobile terminal unlocks the first lock screen, the second lock screen, and the third lock screen.

Although the first unlocking instruction is for the first lock screen, the second lock screen and the third lock screen can be unlocked at the same time. In other words, after the user unlocks the first lock screen, the system automatically unlocks the second lock screen and the third lock screen. On Android phones, it can be that WMS removes the first lock screen, the second lock screen, and the third lock screen from the lock screen window stack. Optionally, when the first lock screen is at the top, the user will automatically unlock the second lock screen and the third lock screen after unlocking the first lock screen. It is understandable that the first lock screen may not be the top one, but under the second lock screen or the third lock screen. At this time, the first unlock command can "pass through" the top lock screen and unlock The first lock screen that is not on the top, the second lock screen and the third lock screen.

After unlocking the first, second, and third lock screens, you can directly enter the first application or display the system desktop. There is no restriction here.

Through the above method, more third-party lock screens can be easily unlocked without requiring the user to unlock each third-party lock screen one by one.

Figure 6 provides another method for unlocking the lock screen, including the following steps:

601: The mobile terminal receives a first unlocking instruction for unlocking the first lock screen, and the mobile terminal is provided with a first lock screen provided by a first application, a second lock screen provided by a second application, and a system lock screen provided by the system.

Among them, the system lock screen may include a secure lock screen and a non-secure lock screen (such as a magazine lock screen), may only include a secure lock screen, or may only include a non-secure lock screen. There is no restriction on the up and down sequence of these lock screens.

602: The mobile terminal unlocks the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen.

Although the first unlocking instruction is for the first lock screen, the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen can be unlocked at the same time. That is, after the user unlocks the first lock screen, the system automatically unlocks the second lock screen and the non-secure lock screen in the system lock screen. On Android phones, it can be that WMS removes the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen from the lock screen window stack.

For the security lock screen in the system lock screen (if it exists), for security reasons, you can ask the user to unlock after unlocking the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen; users After successfully unlocking the security lock screen, the mobile terminal can be used normally. Of course, for the sake of convenience, it is also possible to automatically unlock the secure lock screen while unlocking the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen.

Optionally, after step 601 and before step 602, step 603 may be included: determining whether the system lock screen includes a security lock screen. If the security lock screen is included, unlock the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen; if the security lock screen is not included, unlock the first lock screen, the second lock screen, and the system lock Screen.

After unlocking the first lock screen, the second lock screen, and the non-secure lock screen in the system lock screen, you can directly enter the first application or display the system desktop, and there is no restriction here.

Figure 7 provides another method of locking and unlocking the screen, including the following steps:

701: The mobile terminal receives a second unlocking instruction for unlocking the system lock screen. The mobile terminal is provided with a first lock screen provided by a first application, a second lock screen provided by a second application, and a system lock screen provided by the system.

Among them, the system lock screen may include a secure lock screen and a non-secure lock screen (such as a magazine lock screen), may only include a secure lock screen, or may only include a non-secure lock screen. There is no restriction on the up and down sequence of the first lock screen, the second lock screen, and the system lock screen. In other words, the system lock screen can be on the top or not on the top. The second unlocking instruction depends on the setting of the system. For example, when the unlocking method of the system lock screen is to enter a password to unlock, the second unlocking instruction is to enter a corresponding password.

702: The mobile terminal unlocks the first lock screen, the second lock screen, and the system lock screen.

Optionally, when the system lock screen is not on the top, the second unlocking instruction may "pass through" other lock screens on the system lock screen, unlocking the first lock screen and the second lock screen while unlocking the system lock screen. On Android phones, it can be that WMS removes the first lock screen, the second lock screen, and the system lock screen from the lock screen window stack.

After unlocking the first lock screen, the second lock screen, and the system lock screen, the system desktop can be displayed directly, and there is no restriction here.

Figure 8 provides another method of locking and unlocking the screen, including the following steps:

802: The mobile terminal judges whether the first unlocking instruction comes from an authorized user.

An authorized user, also called a legal user, is the owner of the mobile terminal with the authority to use it. By judging whether the first unlocking instruction comes from an authorized user, it can bring greater operational convenience to the authorized user. For unauthorized users, this quick unlocking method may not be provided.

There may be multiple methods for judging whether the first unlocking instruction comes from an authorized user, and one available method may be verification through physiological characteristics. For example, fingerprint verification, face recognition, iris recognition, voiceprint verification, etc. can be used to verify whether the user is an authorized user. Optionally, the mobile terminal may collect corresponding user physiological characteristics and compare them with pre-stored authorized user physiological characteristics. If the verification is successful, it means that the first unlocking instruction issued by the authorized user is indicated.

Optionally, it is also possible to determine whether the first unlocking instruction comes from an authorized user by verifying the user's usage habits. For example, the mobile terminal can record the history of authorized users to use the mobile terminal, and obtain the usage law of authorized users to use the mobile terminal through statistics (some user operation behaviors that do not conform to the usage law can be eliminated in the statistical process). For example, authorized users often use mobile terminals at home between 7:30-9:00 in the morning, and use mobile terminals at the company from 12:00-14:00 at noon. The mobile terminal can count the time and place of authorized users. Habits of the use of three dimensions. After receiving the first unlocking instruction, the mobile terminal can detect the time and place when the first unlocking instruction is received, and compare it with the authorized user's usage habits. If it meets the requirements, it means that the first unlocking instruction is more likely to be issued by the authorized user of.

803: If the first unlocking instruction comes from an authorized user, the mobile terminal unlocks the first lock screen and the second lock screen.

If the first unlocking instruction comes from an authorized user, the first lock screen and the second lock screen are automatically unlocked, which improves the use experience of the authorized user.

901: The mobile terminal receives a first unlocking instruction for unlocking the first lock screen, and the mobile terminal is provided with a first lock screen provided by a first application and a second lock screen provided by a second application.

902: The mobile terminal detects the time interval between the lock time of the first screen lock and the reception time of receiving the first unlocking instruction, and determines whether the time interval is within a preset time interval.

If the user has just used the mobile terminal, if the mobile terminal is used again after a short period of time, the user experience will be poor if it is unlocked multiple times; and the user has used the mobile terminal just now, it is more likely to be an authorized user. Therefore, in the case of using a mobile terminal just now, multiple lock screens can be automatically unlocked to improve user experience. In order to determine whether the mobile terminal has just been used, the time interval between two time points can be detected. The two time points include: (1) the lock time of the first screen lock to lock the mobile terminal on the system; (2) the mobile terminal The time when the first unlocking instruction was received. If the time interval between these two time points is within the preset time interval (for example, 1 minute), it means that the user has just used the mobile terminal.

903: If the time interval is within the preset time interval, the mobile terminal unlocks the first lock screen and the second lock screen.
