Description

Technical Field

[0001] The embodiments of the present application relate to the field of intelligent terminal technology, and in particular to a method, apparatus and terminal device for releasing startup resources. Background Art

[0002] The cold start of an Android application is usually a time-consuming process. After creating the corresponding process and activity (Activity) of the application and starting the Activity, the interface drawing and display will begin. The whole process will consume a lot of resources on the central processing unit (CPU), memory (memory) and input output (IO), which is a typical load scenario. If the application retreats to the background before it is fully started, for example, the home key is pressed before the first frame is drawn, the terminal device will continue the startup process of the above application in the background, which becomes the background load of the terminal device. In the scenario of continuous and rapid application startup, the user will click to start an application, quickly return to the desktop, and then quickly click to start the next application, and the cycle continues. At the same time point, there may be multiple applications in the background of the terminal device that are all starting up. The computing overhead and resource requirements of the terminal device are very high, which can easily cause the terminal device to freeze. Summary of the invention

[0027] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0028] Figure 1 This is a schematic diagram of a scenario where applications are started quickly and continuously, such as Figure 1 As shown, in the usage scenario of continuous and rapid application startup, after the user clicks to start application 1, the terminal device starts to start application 1 and displays the interface of application 1. During the startup of application 1, the user returns application 1 to the background to start by pressing the home button, and then the user quickly clicks to start application 2, the terminal device starts to start application 2 and displays the interface of application 2. During the startup of application 2, the user returns application 2 to the background to start by pressing the home button, and then the user quickly clicks to start application 3, the terminal device starts to start application 3 and displays the interface of application 3. In this way, when the terminal device starts to display the interface of application 3, both application 1 and application 2 are in the startup process in the background of the terminal device, which has a high computing overhead and resource requirements for the terminal device, and is likely to cause the terminal device to freeze.

[0029] To address this issue, the commonly used existing related technology is to freeze the process of the application running in the background. For example, 500ms, 1s or 2s after the application process returns to the background, the application process is set to a non-schedulable state, so that the application process will not be scheduled by the CPU, thereby preventing the background process from loading resources; when the above application returns to the foreground to run, the application process is set to the running state again, and the startup process of the application continues.

[0030] However, freezing the application process requires status judgment, and the process is usually frozen some time after the application process has been in the background. The freezing judgment needs to be combined with data such as the process call situation, process status, and process priority. For application processes that are in the background before the cold start is completed, they often do not meet the freezing conditions and may not be frozen. Therefore, the process freezing solution cannot effectively alleviate the high load of background application processes in the scenario of continuous and rapid application startup.

[0031] Based on the above problems, an embodiment of the present application provides a method for releasing startup resources, which checks and kills the processes of applications that retreat to the background before completing startup, and prevents the application from starting in the background, thereby ensuring the resource supply of the foreground process and avoiding terminal device freezes.

[0032] The method for releasing startup resources provided in the embodiment of the present application can be applied to terminal devices, wherein the above-mentioned terminal devices can be smart phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPC), netbooks or personal digital assistants (PDA) and other devices; the embodiment of the present application does not impose any restrictions on the specific type of terminal devices.

[0037] The processor 110 may also be provided with a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may store instructions or data that the processor 110 has just used or cyclically used. If the processor 110 needs to use the instruction or data again, it may be directly called from the memory.

In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

[0044] The modem processor may include a modulator and a demodulator. Among them, the modulator is used to modulate the low-frequency baseband signal to be sent into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After the low-frequency baseband signal is processed by the baseband processor, it is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

[0045] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to the terminal device 100. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, modulates the frequency of the electromagnetic wave signal and performs filtering, and sends the processed signal to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, modulate the frequency of it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0046] In some embodiments, the antenna 1 of the terminal device 100 is coupled to the mobile communication module 150, and the antenna 2 is coupled to the wireless communication module 160, so that the terminal device 100 can communicate with the network and other devices through wireless communication technology.

[0047] The terminal device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs, which execute program instructions to generate or change display information.

[0048] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel.

[0049] The terminal device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0050] ISP is used to process the data fed back by camera 193. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to ISP for processing and converts it into an image visible to the naked eye. ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, ISP can be set in camera 193.

[0051] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the terminal device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

Through NPU, applications such as intelligent cognition of the terminal device 100 can be realized, such as image recognition, face recognition, voice recognition, text understanding, etc.

[0055] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the terminal device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function, such as storing music, video and other files in the external memory card.

[0056] The internal memory 121 can be used to store computer executable program codes, which include instructions. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area may store data created during the use of the terminal device 100 (such as audio data, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 110 executes various functional applications and data processing of the terminal device 100 by running instructions stored in the internal memory 121, and / or instructions stored in a memory provided in the processor.

[0057] The terminal device 100 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0058] The audio module 170 is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signals. The audio module 170 can also be used to encode and decode audio signals. In some embodiments, the audio module 170 can be arranged in the processor 110, or some functional modules of the audio module 170 can be arranged in the processor 110.

[0059] The speaker 170A, also called a "speaker", is used to convert an audio electrical signal into a sound signal. The terminal device 100 can listen to music or listen to a hands-free call through the speaker 170A.

[0060] The receiver 170B, also called a "handset", is used to convert audio electrical signals into sound signals. When the terminal device 100 receives a call or voice message, the voice can be received by placing the receiver 170B close to the ear.

[0061] Microphone 170C, also called "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can speak by putting their mouth close to the microphone 170C to input the sound signal into the microphone 170C. The terminal device 100 can be provided with at least one microphone 170C. In other embodiments, the terminal device 100 can be provided with two microphones 170C, which can not only collect sound signals but also realize noise reduction function. In other embodiments, the terminal device 100 can also be provided with three, four or more microphones 170C to realize the collection of sound signals, noise reduction, identification of sound sources, realization of directional recording function, etc.

[0062] The earphone interface 170D is used to connect a wired earphone and can be a USB interface 130 or a 3.5 mm open mobile terminal platform (OMTP) standard interface or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0064] Motor 191 can generate vibration prompts. Motor 191 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. For touch operations acting on different areas of the display screen 194, motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0065] Indicator 192 may be an indicator light, which may be used to indicate charging status, power changes, messages, missed calls, notifications, etc.

[0066] The SIM card interface 195 is used to connect a SIM card.

The terminal device 100 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, and the like. Multiple cards can be inserted into the same SIM card interface 195 at the same time. The types of the multiple cards can be the same or different. The SIM card interface 195 can also be compatible with different types of SIM cards. The SIM card interface 195 can also be compatible with external memory cards. The terminal device 100 interacts with the network through the SIM card to implement functions such as calls and data communications. In some embodiments, the terminal device 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the terminal device 100 and cannot be separated from the terminal device 100.

[0067] For ease of understanding, the following embodiments of the present application will be described in detail with Figure 2 Taking the terminal device of the shown structure as an example, combined with the accompanying drawings and application scenarios, the method for releasing the startup resources provided in the embodiment of the present application is specifically explained.

[0068] In scenarios related to continuous and rapid application startup, if the application retreats to the background before the cold start is completed, it will bring a high background load and easily cause the foreground application to freeze. In order to reduce the background load in this case, the embodiment of the present application kills such background load processes through killing to ensure the supply of system resources of the terminal device 100 to the foreground application process.

[0069] Figure 3 A schematic diagram of a method for releasing startup resources provided by an embodiment of the present application is shown in FIG. Figure 3As shown, when application 2 is started, application 1 returns to the background and has not yet completed the startup, so the terminal device 100 kills the process of application 1 and releases the background startup resources occupied by application 1; similarly, when application 3 is started, application 2 returns to the background and has not yet completed the startup, so the terminal device 100 kills the process of application 2 and releases the background startup resources occupied by application 2.

[0070] Figure 4 A flowchart of a method for releasing startup resources provided in one embodiment of the present application is shown in FIG. Figure 4 As shown, the above method for releasing the startup resources may include:

[0071] Step 401 , in response to detecting that an application has retreated to the background, the terminal device 100 obtains the drawing time of the first frame of the application and the startup duration of the application.

[0072] The drawing time of the first frame of the application may be the moment when the first frame of the application starts to be drawn; the startup duration of the application may be the length of time from the moment when the process of the application is created to the moment when the application exits to the background.

[0073] Step 402, if the drawing time of the first frame of the above application is not updated, or the startup duration of the above application is less than or equal to the duration threshold, the terminal device 100 kills the process of the above application to release the startup resources occupied by the background of the above application.

[0074] Among them, the above-mentioned duration threshold can be pre-set according to system performance and / or implementation requirements during specific implementation, or the above-mentioned duration threshold can also be adaptively adjusted according to different applications. This embodiment does not limit the size of the above-mentioned duration threshold.

[0075] Specifically, when the first frame of the application has not started to be drawn, the drawing time of the first frame of the application is an initial value. After the first frame of the application starts to be drawn, the drawing time of the first frame of the application is updated to the moment when the first frame of the application starts to be drawn. Therefore, in this embodiment, the fact that the drawing time of the first frame of the application has not been updated indicates that the first frame of the application has not started to be drawn.

[0076] That is to say, in this embodiment, when the first frame of the above application has not yet started to be drawn, or the startup duration of the above application is less than or equal to the duration threshold, the terminal device 100 kills the process of the above application to release the startup resources occupied by the background of the above application.

[0077] Specifically, the terminal device 100 may check and kill the process of the above application by: the terminal device 100 obtains an identifier (process identifier, PID) of the process of the above application, and checks and kills the process corresponding to the above identifier.

[0078] In this embodiment, if the application startup duration is less than or equal to the duration threshold, or the first frame of the application has not yet started to be drawn, it means that the scenario at this time is likely that the user has just clicked the icon of the application to trigger the startup of the application, but immediately retreated the application to the background, which means that the user is likely not to use the application next. In addition, if the application startup duration is less than or equal to the threshold, or the first frame of the application has not yet started to be drawn, it also means that after the terminal device 100 responds to the user's operation of clicking the application icon, too many system resources have not been used to cold-start the application. Even if the user subsequently switches the application back to the foreground, or the user clicks the application icon again, the cost of cold-starting the application from the beginning will not be too large.

[0079] Therefore, based on the fact that the startup duration of the application is less than or equal to the duration threshold, or the first frame of the application has not yet started to be drawn, the terminal device 100 can accurately identify the applications in the background that the user is likely not to use next, and kill the processes of such applications. On the one hand, it will not have a substantial impact on the user experience, and on the other hand, it can save the system resources consumed by the startup of such applications in the background and reduce terminal lag.

[0080] In the above-mentioned method for releasing startup resources, the terminal device 100 obtains the drawing time of the first frame of the above-mentioned application and the startup duration of the above-mentioned application in response to detecting that the application has retreated to the background. If the drawing time of the first frame of the above-mentioned application has not been updated, or the startup duration of the above-mentioned application is less than or equal to the duration threshold, the terminal device 100 kills the process of the above-mentioned application to release the startup resources occupied by the above-mentioned application in the background. In this way, the terminal device 100 can accurately identify the application in the background that the user is likely to not use next based on the startup duration of the application being less than or equal to the duration threshold, or the first frame of the application has not yet started to be drawn, and kill the process of the application to release the startup resources occupied by the application in the background. This will not affect the user experience, but can also save the system resources consumed by the application when it is started in the background, ensure the supply of system resources to the process of the application running in the foreground, and reduce the jamming of the terminal device 100.

[0081] Figure 5 A flowchart of a method for releasing startup resources provided in another embodiment of the present application is shown in FIG. Figure 5 As shown, this application Figure 4 In the illustrated embodiment, after step 401, the following steps may also be included:

[0082] Step 501: If the rendering time of the first frame of the application has been updated, the terminal device 100 determines whether the startup duration of the application is less than or equal to a duration threshold, and then executes step 502 or step 503.

[0083] Step 502: If the startup duration of the above application is less than or equal to the duration threshold, the terminal device 100 kills the process of the above application to release the startup resources occupied by the background of the above application.

[0084] Step 503: If the startup duration of the above application is greater than the duration threshold, the terminal device 100 returns the above application to the background.

[0085] In this embodiment, after the terminal device 100 obtains the drawing time of the first frame of the above-mentioned application and the startup duration of the above-mentioned application, if the drawing time of the first frame of the above-mentioned application has been updated, it means that the terminal device 100 has started to draw the first frame of the application. At this time, the terminal device 100 can continue to determine whether the startup duration of the application is less than or equal to the duration threshold. If so, the terminal device 100 can determine that the above-mentioned application belongs to the scenario of not being fully started and exiting the background. In this way, the terminal device 100 can check and kill the process of the above-mentioned application to release the startup resources occupied by the background application, ensure the supply of system resources of the terminal device 100 to the process of the application running in the foreground, and reduce the lag of the terminal device 100.

[0086] Figure 6 A flowchart of a method for releasing startup resources provided in another embodiment of the present application is shown in FIG. Figure 6 As shown, this application Figure 4 In the illustrated embodiment, after step 401, the following steps may also be included:

[0087] Step 601: If the startup duration of the application is greater than the duration threshold, it is determined whether the drawing time of the first frame of the application has been updated. Then, step 602 or step 603 is executed.

[0088] Step 602: If the drawing time of the first frame of the above application is not updated, the terminal device 100 kills the process of the above application to release the startup resources occupied by the background of the above application.

[0089] Step 603: If the drawing time of the first frame of the above application has been updated, the terminal device 100 returns the above application to the background.

[0090] In this embodiment, after the terminal device 100 obtains the drawing time of the first frame of the above-mentioned application and the startup duration of the above-mentioned application, if the startup duration of the above-mentioned application is greater than the duration threshold, the terminal device 100 can continue to determine whether the drawing time of the first frame of the above-mentioned application has been updated. If the drawing time of the first frame of the above-mentioned application has not been updated, it means that the terminal device 100 has not started to draw the first frame of the above-mentioned application. Then, the terminal device 100 can determine that the above-mentioned application belongs to the scenario of not being fully started and exiting the background. In this way, the terminal device 100 can check and kill the process of the above-mentioned application to release the startup resources occupied by the background application, ensure the supply of system resources of the terminal device 100 to the process of the application running in the foreground, and reduce the lag of the terminal device 100.
