S302: The mobile phone 100 responds to the first operation and obtains the interface transparency parameter of the first interface.

Since whether the application has a transparent interface during the startup process is related to the logic set by the developer during the application development stage, when the application itself is set to create a transparent interface first during the startup process and then create a real interface, then this type of application will There will be a transparent interface. It should be understood that the transparent interface may correspond to the transparent Activity below; the real interface may correspond to the target Activity below.

When the application itself is not set to create a transparent interface first during the startup process, and then create the real interface, that is, directly create the real interface, then such applications will not have a transparent interface during the startup process.

In the existing technology, only some of the mobile phone applications may have a transparent interface during the startup process. When the user triggers the opening operation of the application, the mobile phone does not know whether the application opened by the user will have a transparent interface. Therefore, based on the methods provided by various embodiments of the present application, the mobile phone 100 can obtain the interface transparency parameter of the first interface, and then determine whether the first interface is a transparent interface based on the interface transparency parameter.

S303: The mobile phone 100 determines whether the first interface is a transparent interface according to the interface transparency parameter of the first interface. If the first interface is transparent If the interface is clear, continue to execute S304.

In some embodiments, the mobile phone 100 can determine whether the interface is a transparent interface according to the interface transparency parameter. Specifically, when the interface transparency parameter is greater than the transparency threshold, the interface can be considered to be a non-transparent interface; when the interface transparency parameter is less than or equal to the transparency threshold, the interface can be considered to be a transparent interface. For example, assume that the interface transparency parameter ranges from 0 to 1, with 0 indicating that the interface is completely transparent and 1 indicating that the interface is completely opaque. For example, if the transparency threshold is 0, then when the interface transparency parameter is greater than 0, the interface is a non-transparent interface; when the interface transparency parameter is less than or equal to 0, the interface is a transparent interface.

As another example, assuming that the value range of the transparency parameter is 0 to 255 and the transparency threshold is 10, then when the interface transparency parameter is less than 10, the mobile phone 100 can determine that the interface is a transparent interface; when the interface transparency parameter is greater than or equal to 10, The mobile phone 100 can determine that the interface is a non-transparent interface.

It should be understood that the above example is only an example. In actual applications, when the interface transparency parameter is greater than the transparency threshold, the interface is a transparent interface; when the interface transparency parameter is less than or equal to the transparency threshold, the interface is a non-transparent interface. This application does not limit this.

In some embodiments, the mobile phone 100 can determine whether the first interface is a transparent interface according to the setAlpha() function.

It should be understood that if the first interface is a transparent interface, then the first application is an application that will have a transparent interface during the startup process; if the first interface is not a transparent interface, then the first application will not have a transparent interface during the startup process. application.

S304: Mobile phone 100 starts the target activity.

In some embodiments, when the first interface is a transparent interface, the mobile phone 100 can skip the process of creating the transparent interface and directly start the target activity (Activity). The mobile phone 100 does not need to create a transparent Activity. Compared with the existing technology, one fewer Activity can be created and the application hot start time can be shortened.

S305: The mobile phone 100 draws the second interface and starts the first application.

The second interface is the interface displayed by the first application before switching to the background application. For example, assuming that the first application is Application, for example, the user has opened the Huawei official website through the Baidu application and is browsing the homepage of the Huawei official website. If the user slides up to return to the main interface at this time, the Baidu application can run in the background. Then, when the user opens the Baidu application again, if the first interface is a transparent interface, the mobile phone 100 can directly display the second interface, which is the interface corresponding to the homepage of Huawei's official website, thereby completing the hot start process of the Baidu application.

In the embodiment of the present application, when the mobile phone 100 determines that the first interface is a transparent interface, it can skip the process of creating the transparent interface, without creating a transparent Activity, and directly start the target Activity, and the interface corresponding to the target Activity is the second interface. If according to the solution of the existing technology, the mobile phone 100 does not determine whether the first interface is a transparent interface, and before S304, the mobile phone 100 also needs to create a transparent Activity. However, the solution of the embodiment of the present application can reduce transparency compared to the existing technology. The creation of Activity shortens the time of application hot start and accelerates the process of application hot start.

The application hot start method in the embodiment of the present application will be introduced below in combination with the software architecture. As shown in Figure 4, it is a flow chart of an application hot start method provided by an embodiment of the present application. Referring to Figure 4, the method may include:

S401: The first application receives the first operation.

Wherein, the first application is a background application, and the first operation is a triggering operation for starting the first application, which may be, for example, a user's click operation on an application icon of the first application on the desktop. Of course, the first operation can also be other operations, such as clicking the window corresponding to the first application in the multi-tasking window, or it can also be opening the first application through the voice assistant. For example, the user can issue the command "Xiaoyi Xiaoyi" , open XX application", etc., this application does not limit this.

In some embodiments, before receiving the first operation, the first application may switch from foreground running to background running. For example, the first application may receive a second operation to switch the first application to the background, and then the mobile phone 100 may respond to the second operation and switch the first application from running in the foreground to running in the background. For example, the second operation may be an operation of sliding up to return to the desktop (main interface).

S402: The desktop application notifies AMS to start the activity of the first application.

In some embodiments, after the user clicks the first application on the desktop, the process of the desktop application can call the startActivity() function and send a message to AMS through the inter-process communication mechanism Binder mechanism, so that AMS starts the Activity of the first application. . Since the first application is a background application and has an application process, AMS does not need to create an application process again.

It should be understood that before the first application is switched to a background application and the user opens the first application as a foreground application, AMS has already created the application process of the application. Therefore, when the user opens the first application again, there is no need to create it again. application process.

S403: AMS determines whether the first interface is a transparent interface.

In some embodiments, when the first interface is a transparent interface, continue to execute S404.

In some embodiments, the AMS can obtain the interface transparency parameter of the first interface, and then determine whether the first interface is a transparent interface based on the interface transparency parameter. If the interface transparency parameter of the first interface is greater than the transparency threshold, the first interface is a non-transparent interface; if the interface transparency parameter of the first interface is less than or equal to the transparency threshold, the first interface is a transparent interface. Of course, the above determination method is only an example. For example, when the interface transparency parameter of the first interface is less than the transparency threshold, it is determined that the first interface is a transparent interface; when the transparency parameter of the first interface is greater than or equal to the transparency threshold, it is determined that The first interface is a non-transparent interface.

S404: AMS skips the creation of transparent interfaces.

In the embodiment of this application, if the AMS determines that the first interface is a transparent interface, the AMS can notify the first application process to execute the ActivityPause() function through the Binder mechanism to intercept the transparent Activity. That is to say, if AMS identifies a transparent Activity during the hot start of the first application, the creation of the transparent Activity is skipped.

S405: AMS starts the target Activity.

In some embodiments, AMS skips the creation of transparent Activity and can directly start the target Activity and execute the life cycle methods of the target Activity, such as onstart(), onresume() and other methods.

S406: The first application draws the second interface and completes the hot start.

The second interface is the interface displayed by the first application before switching to the background application.

In some embodiments, the first application may draw a second interface corresponding to the target Activity, and then display the second interface, thereby completing the hot start process of the first application.

Through the above embodiments, when AMS recognizes that the first interface is a transparent interface, it can actively skip the creation of the transparent interface, which can shorten the application hot start time and improve the efficiency of application hot start.
