Description
Technical Field
The present disclosure relates to the field of software technologies, and in particular, to a method and an apparatus for controlling software execution.
Background
In the native android system, the software architecture is mainly divided into three layers: an application layer, a middle layer and a bottom layer. Taking the fingerprint software architecture as an example, the application layer may be an unlocking program or various payment tools, etc. The application layer does not need to care about the specific implementation details of the fingerprint, and only needs to call the input interface and the identification interface provided by the middle layer. The main function of the middle layer is to abstract the underlying implementation details. Taking the fingerprint software architecture as an example, the middle layer is used for providing the standard functions of the fingerprint to the application layer. The bottom layer is directly communicated with the fingerprint sensor and is a place for realizing various functions of the fingerprint. Since each supplier has its implementation scheme due to different technologies used by each supplier, the underlying services are different from one another, and different suppliers have different modules.
In the related art, only one provider can be configured in a software architecture of one piece of software, in other words, only one piece of software can support the underlying service provided by one provider. In actual engineering projects, cell phone manufacturers often need to introduce two, three or more suppliers. The software architecture in the related art cannot meet the support of multiple suppliers, and cannot realize dynamic compatibility of the bottom layer services provided by multiple suppliers.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a flowchart illustrating an execution control method of software according to an exemplary embodiment. The method can be applied to terminals such as mobile phones or tablet computers. As shown in fig. 1, the method includes the following steps.
In step S11, the value of the provider global variable corresponding to the software is determined by the middle layer of the software.
In this embodiment, the value of the provider Global variable (e.g., Global _ variable) may be read by the middle layer of software. Wherein a provider may refer to a provider of an underlying service. Taking the underlying service as the fingerprint identification service as an example, the provider may be a provider of the fingerprint identification service. The value of the provider global variable may correspond to the provider that provides the underlying service.
As an example of the present embodiment, when the provider Global variable is initially set, the value of the provider Global variable is set to NULL (e.g., Global _ variable ═ NULL).
In one possible implementation manner, determining, by the middle layer of the software, a value of a provider global variable corresponding to the software includes: when the software is initialized, the middle layer of the software determines the value of the provider global variable corresponding to the software. In this implementation, the value of the provider global variable corresponding to the software may be determined by a middle layer of the software at the time of initialization of the software, for example, at the time of startup of the software.
In another possible implementation manner, the value of the provider global variable corresponding to the software may be determined by a middle layer of the software in a case where the bottom layer service corresponding to the provider global variable needs to be called. Taking fingerprint software (such as unlocking software, payment software, and the like) as an example, the value of the provider global variable corresponding to the fingerprint software can be determined through the middle layer of the fingerprint software when the fingerprint identification service needs to be invoked.
In step S12, if the value of the provider global variable is null, the underlying service corresponding to each provider in the provider list maintained by the middle tier is loaded.
In this embodiment, a provider list is maintained at a middle tier of software, which may include information for multiple providers.
By loading the bottom layer service corresponding to each provider in the provider list maintained by the middle layer under the condition that the value of the provider global variable is null, the dynamic detection of the provider of the bottom layer service can be realized.
Fig. 2 is a schematic diagram illustrating a software architecture in an execution control method of software according to an exemplary embodiment. As an example of this embodiment, the software architecture of the software includes an application layer, a middle layer, and a bottom layer. The middle layer maintains a provider list, which may record values of global variables corresponding to the providers, for example, the values of the global variables corresponding to the providers include A, B, C, D. In this example, in a case where the value of the provider Global variable is NULL (for example, Global _ variable ═ NULL), the underlying services corresponding to the respective providers in the provider list maintained by the middle layer may be sequentially loaded until the underlying service corresponding to a certain provider is successfully loaded. For example, the values of the global variables corresponding to the providers recorded in the provider list include A, B, C, D, etc., and the loading may be started from the bottom layer service corresponding to a in the order from a to D until the loading of the bottom layer service corresponding to a certain provider is successful.
In one possible implementation, the underlying services include at least one of: fingerprint identification services, touch sensing services, and camera services. The fingerprint identification service can be an underlying service related to fingerprint identification provided by a provider; the touch sensing service can be a bottom layer service related to touch screen sensing provided by a provider; the camera service may be an underlying service provided by a provider that is related to the camera application. It should be noted that the underlying services may also include underlying services related to various sensors of the terminal, and are not limited herein.
In step S13, when the underlying service corresponding to the first provider is successfully loaded, the provider global variable is assigned with a value of the global variable corresponding to the first provider, where the first provider is any one provider in the provider list.
For example, in a case that the loading of the underlying service corresponding to the first provider is successful, for example, the value of the Global variable corresponding to the first provider is B, the provider Global variable is assigned to B (for example, Global _ variable is set to B).
By giving the value of the global variable corresponding to the first provider to the provider global variable when the loading of the underlying service corresponding to the first provider is successful, the underlying service (for example, the underlying service corresponding to B) corresponding to the value of the provider global variable can be directly loaded after the software is restarted or the terminal is restarted without repeatedly performing dynamic detection on the provider, so that the starting speed of the software and/or the reaction speed of the underlying service can be increased.
The embodiment can support a plurality of providers and realize dynamic compatibility of the bottom layer services provided by the plurality of providers.
In one possible implementation, after determining, by the middle layer of the software, a value of a provider global variable corresponding to the software, the method further includes: and loading the bottom layer service corresponding to the value of the global variable of the provider under the condition that the value of the global variable of the provider is not null. In the implementation mode, under the condition that the value of the global variable of the provider is not null, the bottom layer service corresponding to the value of the global variable of the provider is directly loaded without repeatedly carrying out dynamic detection on the provider providing the bottom layer service, so that the starting speed of software and/or the reaction speed of the bottom layer service can be improved.
Fig. 3 is a flowchart illustrating an execution control method of software according to an example of an exemplary embodiment. As shown in fig. 3, the method includes:
in step S31, the value of the provider global variable corresponding to the software is determined by the middle layer of the software.
Step S31 is entered into the above description of step S11.
In step S32, if the value of the provider global variable is null, the underlying service corresponding to each provider in the provider list maintained by the middle tier is loaded.
Step S32 is entered into the above description of step S12.
In step S33, when the underlying service corresponding to the first provider is successfully loaded, the provider global variable is assigned with a value of the global variable corresponding to the first provider, where the first provider is any one provider in the provider list.
Step S33 is entered into the above description of step S13.
In step S34, if the value of the provider global variable is not empty, the underlying service corresponding to the value of the provider global variable is loaded.
For example, in the case that the value of the provider global variable is B, the underlying service corresponding to B is loaded.
In step S35, if the underlying service corresponding to the value of the provider global variable fails to be loaded, the underlying service corresponding to each provider in the provider list is loaded.
In this example, when the loading of the underlying service corresponding to the value of the provider global variable fails, the underlying service corresponding to each provider in the provider list is loaded, so that the provider can be dynamically detected again. For example, after-sale service can automatically identify and reload the underlying service corresponding to A if the original B fingerprint sensor is replaced by the A fingerprint sensor.
In step S36, when the underlying service corresponding to the second provider is successfully loaded, the value of the global variable corresponding to the second provider is assigned to the provider global variable, where the second provider is any one provider in the provider list.
Under the condition that the bottom layer service corresponding to the second provider is loaded successfully, the value of the global variable corresponding to the second provider is given to the provider global variable, so that the bottom layer service corresponding to the value of the provider global variable can be directly loaded without repeated dynamic detection after the software is restarted or the terminal is restarted, and the starting speed of the software and/or the reaction speed of the bottom layer service can be increased.
In one possible implementation, the method further includes: and adding the newly added provider into the provider list under the condition that the provider providing the bottom layer service needs to be newly added for the software. In the implementation manner, when a provider providing the underlying service needs to be added to the software, only one item needs to be added to the provider list to implement dynamic support.

Referring to fig. 4, the apparatus includes a global variable determination module 41, a first underlying service loading module 42, and a first global variable assignment module 43. The global variable determination module 41 is configured to determine, by the middle layer of the software, a value of a provider global variable corresponding to the software. The first underlying service loading module 42 is configured to load the underlying service corresponding to each provider in the provider list maintained by the middle layer, when the value of the provider global variable is null. The first global variable assigning module 43 is configured to assign a value of a global variable corresponding to a first provider to the provider global variable when the underlying service corresponding to the first provider is loaded successfully, where the first provider is any one provider in the provider list.

With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
The embodiment can support a plurality of providers, realize dynamic compatibility of bottom layer services provided by the plurality of providers and realize dynamic detection of the providers. By giving the value of the global variable corresponding to the first provider to the provider global variable under the condition that the loading of the underlying service corresponding to the first provider is successful, the underlying service corresponding to the value of the provider global variable can be directly loaded after the software is restarted or the terminal is restarted without repeatedly performing dynamic detection on the provider, so that the starting speed of the software and/or the reaction speed of the underlying service can be increased. Under the condition that a new provider providing bottom-layer service is required to be added to the software, only one new item needs to be added to a provider list to realize dynamic support.
