Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Below in conjunction with specific embodiment, specific implementation of the present invention is described in detail:
Embodiment mono-:
Fig. 1 shows the realization flow of the event broadcast adaptation services method that the embodiment of the present invention one provides, and details are as follows:
In step S201, receive the broadcast of the predefine event of preset operating system kernel transmission.
In embodiments of the present invention, default operating system refers to and can adopt broadcast mechanism to carry out the operating system of message informing, and for example, Android operating system or other adopt the operating system of Linux Kernel kernel.The predefine event can be the event defined in operating system, and for example, USB flash disk plug event, network break-make event, mouse plug event etc., will not enumerate at this.
As example ground, for example, after the user extracts USB flash disk, the Linux Kernel of Android operating system can send Uevent message, to inform that change has occurred user's space storer (USB flash disk) state, after now Netlink monitors and receive this Uevent information, be connected by with carry service (MountService), setting up socket (Socket), be sent to user's space thereby the Uevent information exchange is crossed to the forms of broadcasting.
In step S202, according to the broadcast identification of described broadcast, the broadcast of the described predefine event of inquiry in the broadcast registration list.
In embodiments of the present invention, with a broadcast registration list, store the broadcast of registration.The broadcast of only registering in this broadcast registration list just can be received and then is processed, thereby when this operating system is transplanted to the Another Application platform from an application platform, for interpolation, the change of broadcasting provides the foundation.
In step S203, when inquiring the broadcast of described predefine event, obtain the event response list associated with described broadcast identification.
In embodiments of the present invention, when in the broadcast registration list, inquiring the broadcast of described predefine event, obtain the event response list associated with described broadcast identification, the all response functions with described predefine event correlation in this event response list, have been stored, to respond described predefine event.
In step S204, the state information of event comprised in the broadcast according to described predefine event, travel through described event response list, to obtain the response function associated with described state information of event.
In embodiments of the present invention, state information of event has been described the state variation of event, only has the response function associated with described state information of event just can be acquired.
In step S205, carry out described response function, with the state of the application client that changes described response function association.
In embodiments of the present invention, obtain the response function associated with described state information of event by step S204, carry out these response functions, thereby change the state of the application client of response function association.
As example ground, for example, if a plurality of application client is associated with USB flash disk, (inserts or extract as USB flash disk) when the USB flash disk interface changes, need to change show state or the interface of associated application client USB flash disk.By carrying out these response functions, just can realize the variation of associated application client state.
Preferably, in embodiments of the present invention, described response function is call back function, thereby, when operating system is transplanted to another platform from an application platform, carries out large modification without application programs, can realize the normal operation of application program in this operating system.
The embodiment of the present invention is stored the broadcast of registration with a broadcast registration list, when needs add new broadcast, only need in described broadcast registration list, register and get final product, thereby solved preset operating system and when an application platform is transplanted to the Another Application platform, occurred that event broadcast is difficult to compatible problem, improve the compatibility of preset operating system, reduced the cost that this preset operating system is transplanted.
Further, in another embodiment of the present invention, can also comprise step before step S201: by the broadcast registration of described predefine event in described broadcast registration list.Like this, when preset operating system need to increase new broadcast or former broadcast is modified, only need this broadcast registration just can compatiblely should be broadcasted in the broadcast registration list.For example, mobile-terminal platform and intelligent television platform, the broadcast that both use may be different, now, can realize according to the application platform difference of operating system the increase of new broadcast.
As example ground, particularly, the broadcast registration of described predefine event can be realized by following step to the step in described broadcast registration list:
(1) broadcast identification of described predefine event and corresponding state information of event are added in described broadcast registration list;
(2) in the event response list, the response function associated with described state information of event registered.
In embodiments of the present invention, by above-mentioned steps, can realize the registration of the broadcast of predefine event.When default operating system is other operating systems of Android operating system or use Linux Kernel kernel, can the response function associated with described state information of event be registered in described event response list by AIDL.
In this embodiment, when preset operating system need to increase new broadcast or former broadcast is modified, can be by this broadcast registration be realized in the broadcast registration list, thereby improve the compatibility of operating system, simultaneously, when an application program is transplanted to the Another Application platform from an application platform, by by its event response function registration in the event response list, realize corresponding interface, and then realize the registration of broadcast, simplified the migration process of application program.
One of ordinary skill in the art will appreciate that all or part of step realized in above-described embodiment method is to come the hardware that instruction is relevant to complete by program, described program can be stored in a computer read/write memory medium, described storage medium, as ROM/RAM, disk, CD etc.
Embodiment bis-:
Fig. 3 shows the structure of the event broadcast adaptation services system that the embodiment of the present invention two provides, and for convenience of explanation, only shows the part relevant to the embodiment of the present invention, comprising:
Event response list acquiring unit 33, for when inquiring the broadcast of described predefine event, obtain the event response list associated with described broadcast identification;
Response function acquiring unit 34, for the state information of event that the broadcast according to the predefine event comprises, the list of traversal event response, to obtain the response function associated with described state information of event; And
Response function performance element 35, be used to carrying out described response function, with the state of the application client that changes described response function association.
Wherein, as described in Figure 4, particularly, described broadcast registration unit 31 can comprise:
Broadcast message adding device 311, add described broadcast registration list to for the broadcast identification by described predefine event and corresponding state information of event; And
