Play the audio file.If preset audio attribute is to forbid playing sound, forbid broadcasting based on the audio broadcast message class being pre-created
Put the audio file.For example, detecting the audio broadcast event of application program, AudioTrack, initialization are created
AudioTrack starts audio frequency apparatus (Audio facility information is packaged in AudioSystem class).The audio is obtained to play
The corresponding audio file of event, is decoded the audio file, obtains decoded audio data.To AudioTrack pairs
Before write-in audio data, the memory headroom of application process is inquired according to the uid of the application program, obtains the application program
Preset audio attribute.It determines whether to be written decoded audio data according to the value of preset audio attribute
AudioTrack, to play audio file.For example, forbidding if the value of preset audio attribute is 1 by decoded audio number
According to write-in AudioTrack.Since the object of decoded audio data write-in AudioTrack could be played the audio data
The sound of corresponding audio file, if forbidding audio data AudioTrack is written, can not playing audio-fequency data it is corresponding
The sound of audio file, realization forbid the application program to play sound.If the value of preset audio attribute is 0, allow to solve
AudioTrack is written in audio data after code, realizes the sound of the corresponding audio file of playing audio-fequency data, and realization allows this
Application program plays sound.
The technical solution of the embodiment of the present application decodes the audio in the audio broadcast event for detecting application program
The corresponding audio file of broadcast event；And obtain the preset audio attribute of the application program；According to the preset audio attribute
It determines whether the decoded audio file audio broadcast message class being pre-created is written；If so, by the audio file
The audio broadcast message class being pre-created is written, to play the sound of the audio file.By using above-mentioned technical proposal, detecting

In the embodiment of the present application, active window can be regarded as one it is independent be directly facing user provide interaction and operation
Interface may name the interface in different operating system using different nouns.In order to make it easy to understand, below with Android
(Android) following explanation is carried out for operating system.
In android system, active window is referred to as Activity.Activity, which is one, to be responsible for interacting with user
Component provides screen (can be understood as screen interface, and the display screen of non-physical), so that user's interaction completes certain
Item task.In an android application program, an Activity is usually exactly an individual screen, it above can be with
Show that some controls can also be monitored and handle the event of user.In being managed to Activity, there is two such concept：
Task (task stack) and Stack (active window storehouse).Task corresponds to an application program, and Task is used to store Activity,
One or more Activity can be stored in one Task, and these Activity follow " first-in last-out, last in, first out "
Principle.And Stack is used to be managed Task, in general, each Activity of the Stack to displaying needed for a screen
Affiliated Task is managed, and a Stack can manage one or more Task, and certainly, Stack similarly follows storehouse
Basic management principle.The not necessarily complete independent display screen of screen described here, by taking " two screens " as an example, the two
Screen may be the region that two independent displays respectively show content in a full display screen.Certainly, if terminal has
Two even more than two separate display screens, then " two screens " is also possible to two independent display screens.
In android system, multiwindow mode is supported, it may include span mode, picture-in-picture mode and free schema
(FreeForm).Under multiwindow mode, the Stack where application program can have the size (size) of oneself, may include
Using the terminal screen upper left corner as the coordinate up and down in the coordinate system of origin.For example, (a, b, c, d), general description is one
The coordinate on the boundary of a rectangle, coordinate and the lower right corner that the rectangle upper left corner can be used is indicated, i.e. the top left co-ordinate of rectangle
For (a, b), bottom right angular coordinate is (c, d), and such rectangular area just corresponds to the size of Stack.In Stack using interior layout
It is to be subject to the size of Stack, that is to say, that the corresponding application interface of Activity is carried out in the bounds of size
Display.
Under multiwindow mode, can permit multiple application programs and be in visible state, including system and use it is visible per family
Only system is visible.System and refer to being shown on the display screen with visible per family, and user it can be seen that；Only system
It can be seen that refer to operating system visible, and user is invisible, may be blocked or by the application on foreground as the application to be realized
Display screen outside show.
In the embodiment of the present application, the application interfaces of loading application programs is treated outside display screen and is preloaded, it can be with
It is realized based on the multiwindow mechanism of operating system, the corresponding size of application program is located at by display screen by multiwindow mechanism
It is outer and reach to the sightless purpose of user, to not interfere with the display content of foreground application on the display screen
Display.
In general, may exist a plurality of types of Stack under multiwindow mode, as Home Stack indicates desktop application
The Stack of display, App Stack indicate the Stack that shows of third-party application, can also there is other split screens Stack etc., above-mentioned three
The content for including in kind Stack can be shown on the display screen, and application activity window stack is referred to as in the embodiment of the present application.
Illustratively, the application program to be loaded is preloaded based on the preloading active window storehouse being pre-created to correspond to
Application interface, including：Create the corresponding target process of the application program to be loaded；In the preloading active window being pre-created
The corresponding task stack of the application program to be loaded is created in mouth storehouse；Started in the task stack based on the target process
The corresponding active window of the application program to be loaded；It is drawn based on the active window started and shows the application to be loaded
The corresponding application interface of program.The advantages of this arrangement are as follows due to preloading the corresponding boundary coordinate position of active window storehouse
It, can be based on the preloading active window storehouse except screen coordinate range to be loaded except the coordinate range of display screen
The application interface of application program is drawn and is shown, the operation and display of foreground application will not be interfered, and guarantees that system is steady
It is qualitative, while effectively improving speed when destination application starting.While creating target process, may also include target into
The initialization procedure of journey.In the implementation procedure of above-mentioned steps, it is also possible to be related to the preloading of other resources, as application service is opened
Dynamic, Memory Allocation, file content are read and Network Data Capture etc., the embodiment of the present application to the preloading procedures of other resources not
It limits.
In some embodiments, further include：It is sent to the application program to be loaded and forges focus notice, and based on described
Forge focus notice keep within a preset period of time the corresponding application interface of the application program to be loaded lasting drafting and
Display updates.The advantages of this arrangement are as follows can be in application program to be loaded acquisition focus and in the visible situation of system
The drafting and display for completing application interface, improve the completeness of preloading, and do not have an impact to the focus of foreground application.This Shen
Please the focus in embodiment be also known as input focus, it is mutually indepedent to forge focus focus corresponding with foreground application.In general, right
For current android system, focus is unique, such as the inputs operation focus point such as touches and come into force, for input
Focus information, system end and application end are consistent, and system end will send input to application once modifying input focus information
The changed information of focus information guarantees that system end is consistent with application end input focus information in this approach.The application is implemented
In example, by way of separation system end and application end input focus information, realize that application end can forge the purpose of focus.Specifically
, in the embodiment of the present application, focus notice is forged to preloaded applications, makes preloaded applications that there is focus information, and system end
Focus information be still that correctly, handling can enable preloaded applications normally to draw in this way, reach and all load
Purpose.Focus is present in system end and application end, it is believed that is server-side (server) and client (client), system end note
Focal application is gathered around in record, and application end saves flag bit (flag) and identifies whether oneself has focus.Forge the opportunity of input focus
It can be when the window system of Android increases window newly, when needing to update focus, generate forgery focus and notify and sent.
The method that the method for forging focus can be the change window focus at the end client for calling window, so that the window obtains coke
Point.Specifically, can be carried out based on Binder mechanism forge focus notice transmission, Binder mechanism be android system into
The most common mode communicated between journey, using c/s framework, i.e. client/service architecture.
For some terminals, especially the intelligent terminals such as mobile phone and tablet computer show in order to facilitate the use of user
The display mode of display screen curtain generally includes vertical screen display and transverse screen display, and many application program defaults are shown using vertical screen mode
