s301: the handset 100 detects a first operation on a first application.

The first application is a background application, and the first operation may be an operation for triggering the first application to start by a user, for example, may be a clicking operation on an application icon of the first application. Of course, there are various ways to launch the first application, for example, the first application may also slide up on the display screen, trigger to display the multitasking window, and then click the interface of the first application in the multitasking window, or may also be a voice triggering operation, which is not limited in this application.

In some embodiments, the handset 100 may display the second interface of the first application before detecting the first operation. When the mobile phone 100 detects a second operation of switching the first application to the background on the second interface, the first application may be switched from the foreground operation to the background operation in response to the second operation. For example, the second operation may be an operation to slide up back to the desktop (main interface).

S302: the mobile phone 100 responds to the first operation to obtain the interface transparency parameter of the first interface.

Because whether the application has a transparent interface in the starting process is related to the logic set by a developer in the application development stage, when the application itself sets the transparent interface to be firstly established in the starting process and then the real interface to be established, the transparent interface exists in the starting process of the application. It should be appreciated 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 the transparent interface first and then create the real interface, that is, directly create the real interface, the application will not have the transparent interface in the starting process.

In the prior art, only a part of applications in the mobile phone may have a transparent interface in the starting process, and after the user triggers the starting operation of the applications, it is not known to the mobile phone whether the applications started by the user have the transparent interface. Therefore, based on the method provided in the embodiments of the present application, the mobile phone 100 may 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 a transparent interface, the process continues to S304.

In some embodiments, the mobile phone 100 may determine whether the interface is a transparent interface according to the interface transparency parameter. Specifically, when the transparency parameter of the interface is greater than the transparency threshold, the interface may be considered as a non-transparent interface; when the interface transparency parameter is less than or equal to the transparency threshold, the interface may be considered a transparent interface. Illustratively, it is assumed that the interface transparency parameter is 0-1, 0 indicating that the interface is completely transparent, and 1 indicating that the interface is completely opaque. For example, the transparency threshold is 0, then the interface is a non-transparent interface when the interface transparency parameter is greater than 0, and is a transparent interface when the interface transparency parameter is less than or equal to 0.

For another example, assuming that the transparency parameter has a value ranging from 0 to 255 and the transparency threshold is 10, when the interface transparency parameter is less than 10, the mobile phone 100 may determine that the interface is a transparent interface; when the interface transparency parameter is greater than or equal to 10, the mobile phone 100 may determine that the interface is a non-transparent interface.

It should be understood that the above example is only an example, and in practical application, the interface may be a transparent interface when the transparency parameter of the interface is greater than the transparency threshold; when the transparency parameter of the interface is less than or equal to the transparency threshold, the interface is a non-transparent interface, which is not limited in this application.

In some embodiments, the mobile phone 100 may 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 launch process; if the first interface is not a transparent interface, the first application is an application that does not have a transparent interface during the launch process.

S304: the handset 100 initiates the target activity.

In some embodiments, when the first interface is a transparent interface, the mobile phone 100 may skip the process of creating the transparent interface and directly initiate a target Activity (Activity). The mobile phone 100 may not create transparent Activity, which can reduce the creation of an Activity compared to the prior art, and can shorten the time of application hot start.

S305: the handset 100 draws a second interface to launch the first application.

The second interface is an interface displayed by the first application before the first application is switched to the background application. Exemplary, assume a first applicationIs thatThe application, such as a user, opens the home web through a hundred degree application and is browsing the home page of the home web. If the user is now sliding back up to the main interface, the hundred degrees application may enter background operation. Then, when the user opens the hundred-degree application again, if the first interface is a transparent interface, the mobile phone 100 may directly display a second interface, where the second interface is an interface corresponding to the homepage of the official website, so as to complete the hot start procedure of the hundred-degree application.

In this embodiment of the present application, when determining that the first interface is a transparent interface, the mobile phone 100 may skip the process of creating the transparent interface, and directly start the target Activity without creating the transparent Activity, where the interface corresponding to the target Activity is the second interface. If the mobile phone 100 does not determine whether the first interface is a transparent interface according to the scheme of the prior art, and before S304, the mobile phone 100 needs to create a transparent Activity, but compared with the prior art, the scheme of the embodiment of the present application can reduce the creation of the transparent Activity, shorten the time of application hot start, and accelerate the process of application hot start.

The application hot start method in the embodiment of the present application is described below with reference to a software architecture. Referring to fig. 4, a flowchart of an application hot start method provided in an embodiment of the present application, referring to fig. 4, the method may include:

s401: the first application receives a first operation.

The first application is a background application, and the first operation is a triggering operation for starting the first application, for example, the clicking operation of the application icon of the first application on the desktop by the user may be performed. Of course, the first operation may be other operations, such as clicking a window corresponding to the first application in the multitasking window, or may also be opening the first application through a voice assistant, for example, the user may issue an instruction "small skill, open XX application", which is not limited in this application.

In some embodiments, the first application may switch from a foreground operation to a background operation before receiving the first operation. 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 switch the first application from the foreground operation to the background operation in response to the second operation. The second operation may be, for example, an operation to slide up back to the desktop (main interface).

S402: the desktop application notifies the AMS of the Activity of launching the first application.

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

It should be appreciated that when the user opens the first application as a foreground application before switching to a background application, the AMS has already created an application process for the application, and thus, when the user opens the first application again, there is no need to create an application process again.

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

In some embodiments, when the first interface is a transparent interface, execution continues with S404.

In some embodiments, the AMS may obtain the interface transparency parameter of the first interface and then determine whether the first interface is a transparent interface according to 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; and if the interface transparency parameter of the first interface is smaller than or equal to the transparency threshold, the first interface is a transparent interface. Of course, the above-mentioned judging manner is merely an example, and for example, when the interface transparency parameter of the first interface is smaller than the transparency threshold, it may be determined that the first interface is a transparent interface; and when the transparency parameter of the first interface is greater than or equal to the transparency threshold, determining that the first interface is a non-transparent interface.

S404: AMS skips creation of transparent interfaces.

In this embodiment of the present application, if the AMS determines that the first interface is a transparent interface, the AMS may notify, through the Binder mechanism, the first application process to execute the Activity pause () function, so as to intercept the transparent Activity. That is, if the AMS recognizes a transparent Activity during the hot start of the first application, creation of the transparent Activity is skipped.

S405: the AMS initiates a target Activity.

In some embodiments, the AMS skips creation of transparent activities, may directly launch target activities, execute lifecycle methods of target activities, such as onstart (), onsume (), and the like.

S406: and the first application draws a second interface to finish the hot start.

The second interface is an interface displayed before the first application is switched 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 embodiment, when the AMS identifies that the first interface is the transparent interface, the AMS can actively skip the creation of the transparent interface, so that the time for hot start of the application can be shortened, and the efficiency of hot start of the application can be improved.
