On the one hand, determining the resource information of the resources to be cached through annotations during the compilation period can reduce the code writing; and by indicating the resource information through annotations, developers can easily configure the corresponding cached content (changing the indication information in the annotations), so the maintainability of the code is high; on the other hand, when the code runs, the resource information indicated by the annotations will be cached, thus reducing operations such as repeatedly querying the declaration file, improving the performance of the code, and enhancing the calling speed of the resources.
[0059] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] Figure 4 is a block diagram of an electronic device shown according to an exemplary embodiment. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0065] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0066] The resource calling method according to the embodiments of the present disclosure can be applied to an electronic device, which can be various types of terminal devices or servers. Among them, the terminal can be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, a vehicle-mounted intelligent device, etc.; the server can be an independent physical server, or a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, network services, cloud storage, cloud functions, cloud communications, middleware services, domain name services, security services, content delivery network (CDN) services, and big data and artificial intelligence platforms. The embodiments of the present disclosure do not make any restrictions.
[0067] Figure 1 is a flowchart of a resource calling method shown according to an exemplary embodiment Figure 1 . As Figure 1 shown, the method mainly includes the following steps:
[0068] S11. During the compilation period of the code, parse the resource declaration file, and use an annotation processor to parse the annotations; wherein, the annotations include indication information for indicating resources to be cached, and the declaration file includes resource information of each resource; wherein, the code is code related to resource calling, and the resources to be cached are at least part of the resources in the declaration file;
[0069] S12. During the compilation period of the code, determine the resource information of the resources to be cached from the declaration file based on the parsed indication information;
[0070] S13. During the running period of the code, cache the resource information of the resources to be cached, and call the resources based on the cached resource information.
[0071] In step S11, the electronic device parses the resource declaration file during the compilation period of the code. Here, the code is the code involving resource calls, such as a terminal or server application program that needs to load image resources or file resources, or it can also be a display program for an interface including controls, etc. The resource declaration file is generated during the compilation period of the code. The declaration file includes the resource information of each resource. The resource information of each resource includes at least the resource name and the resource number identifier (Identity Document, ID). Both the resource name and the resource number identifier are used to uniquely identify the resource. Among them, the resource name is created by the developer in the program and is the variable name of the resource. For example, the resource name of a resource in a layout file is "my_button"; while the resource number identifier is generated during the compilation period of the code. The resource number identifier is an integer value and is used to uniquely identify the resource in the code. For example, the resource number identifier corresponding to "my_button" is the hexadecimal data "0x7f080668". The code can further execute the code corresponding to the resource based on the resource number identifier during the running period. For example, perform settings of control attributes, etc.
[0072] In the embodiments of the present disclosure, the declaration file may further include the resource type, the data type corresponding to the resource number identifier, etc. Taking the resource declaration file as the R class file in the Android system as an example, the resource declaration file can be R.txt. The electronic device can generate R.txt during the compilation period and then parse the resource information corresponding to each resource therein.
[0073] Exemplarily, "int drawable ic_wp_amber_fort 0x7f080698" is the resource information of a resource in the declaration file. Among them, "int" indicates that the data type of the resource number identifier is an integer type, "drawable" indicates that the resource is a picture type of resource; "ic_wp_amber_fort" represents the resource name; "0x7f080698" represents the resource number identifier.
[0074] In the embodiments of the present disclosure, the electronic device also uses an annotation processor to parse annotations. Among them, the annotation processor can be a Java-based (Annotation Processing Tool, APT) annotation processor, which is used to scan and process annotations during compilation; the annotation can be, for example, an annotation based on @ResourceNameCache, which can be used to cache the resource name. By marking a method or a field, it indicates that the value of this method or field should be cached so that it can be quickly obtained when used later, instead of recalculating or obtaining it every time.
[0075] Exemplarily, the annotation is: @ResourceNameCache(className = "AiWatermarkResources", type = "drawable", regex = "ic_w[pr]_.*"); where, className is used to identify the class name of the cached resource; type is used to indicate the type of the resource to be cached, for example, "drawable" is an image or graphic resource; regex is the indication information of the resource name, such as "ic_w[pr]_.*" indicating the resources whose names start with ic_wp_ and ic_wr_. In the embodiments of the present disclosure, the electronic device can parse the above annotation using an annotation processor to obtain the information of each of the above fields, that is, the indication information of the resource to be cached, and the resource to be cached is at least part of the resources in the declaration file.
[0076] In step S12, the electronic device determines the resource information of the resource to be cached from the declaration file based on the parsed indication information during the compilation period of the code. In some embodiments, the electronic device can match the indication information with the resource information in the declaration file to determine the resource information of the resource to be cached; in other embodiments, the electronic device can determine the resource information mapped by the indication information based on a preset mapping table.
[0077] In step S13, the electronic device caches the resource information of the resource to be cached during the running period of the code. For example, the cache can exist in the memory of the electronic device. When the resource information is requested, the electronic device first checks whether the required data already exists in the cache. If it exists (this situation is called "cache hit"), the electronic device can directly read the data from the cache. In the embodiments of the present disclosure, the electronic device calls the resource based on the cached resource information, for example, determines the resource number identifier corresponding to the resource name from the cached resource information based on the resource name, so as to execute relevant code based on the resource number identifier, such as image loading or control property setting, etc.
[0078] Generally, where it is necessary to obtain the resource number identifier through the resource name, for example, in the camera intelligent watermark adding mode, there are a large number of image resources used. These resources use the watermark name in the watermark configuration field of the xml configuration file, plus a fixed prefix as the resource name of the image. When loading the image, it is then necessary to obtain the corresponding resource number identifier through these resource names.
[0079] In the related art, during the runtime of the Android system, based on android.content.res.Resources#getIdentifier, the resource ID corresponding to a given resource name is found from the application's resource file (i.e., the resource declaration file). However, due to frequent access to the resource file, the use of a relatively large number of resources will seriously affect performance. In addition, there is also a solution to write code to store the one-to-one mapping of the resource name and the resource number identifier into a Map. This mapping will generate a large amount of code and is not conducive to maintenance. Any addition or deletion requires operation by code maintenance personnel.
[0080] In contrast, in the embodiments of the present disclosure, the electronic device determines the resource information of the resources to be cached during the compilation period of the code and caches the resource information during the runtime, so that the electronic device can call the resources based on the cached resource information. On the one hand, determining the resource information of the resources to be cached through annotations during the compilation period can reduce code writing; and by indicating the resource information through annotations, developers can easily configure the corresponding cached content (changing the indication information in the annotations), so the maintainability of the code is high; on the other hand, when the code runs, the resource information indicated by the annotations will be cached, thereby reducing operations such as repeatedly querying the declaration file, improving the performance of the code, and enhancing the calling speed of the resources.
[0081] In some embodiments, the indication information includes at least part of the identifier of the resource name and / or the resource type; the determining, during the compilation period of the code, the resource information of the resources to be cached from the declaration file based on the parsed indication information includes:
[0082] During the compilation period of the code, use the annotation processor to parse the annotation to obtain at least part of the identifier of the resource name and / or the resource type in the annotation;
[0083] Based on the at least part of the identifier and / or the resource type, match with the resource information of each resource in the declaration file, and determine the resource that matches in the declaration file as the resource to be cached.
[0084] In an embodiment of the present disclosure, the indication information in the annotation includes at least part of the identifier of the resource name and / or the resource type. For example, the aforementioned "ic_wp_" and "ic_wr" are the prefixes of the resource name, and "drawable" indicates the resource type. The electronic device parses the annotation through an annotation processor to obtain at least part of the identifier and / or the resource type, and thus can match the resource information of each resource in the declaration file based on the indication information. For example, after matching based on "ic_wp_" and "ic_wr" with the resource information of each resource in the declaration file, and / or after matching based on "drawable", the above "int drawable ic_wp_amber_fort 0x7f080698" is the resource information of the resource to be cached.
[0085] It should be noted that in an embodiment of the present disclosure, the electronic device can use a regular matching method to determine the resource information of the resource to be cached from the declaration file based on the indication information. In a regular expression, various special characters and grammars can be used to define the way of matching the search pattern. For example, a complete match of characters can be performed based on "drawable", or a partial match of characters can be performed based on "ic_w[pr]_.*".
[0086] It can be understood that in an embodiment of the present disclosure, the electronic device determines the resource to be cached by matching the indication information with the resource information of each resource in the declaration file. The solution is simple and can improve the running performance of the code.
[0087] Figure 2 This is a flow of a resource calling method in an embodiment of the present disclosure Figure 2 The resource information includes a resource name and a resource number identifier. The above Figure 1 The step S13 in may include:
[0088] S13a. During the running period of the code, for each resource to be cached, cache the mapping between the resource name and the resource number identifier;
[0089] S13b. Based on the mapping between the resource name and the resource number identifier corresponding to each resource after caching, call the resource.
[0090] In an embodiment of the present disclosure, when the electronic device caches the resource information of the resource to be cached, what is cached is the resource name and the resource number identifier used to identify the resource, rather than the entire resource information in the declaration file. In addition, what the electronic device caches is the mapping between the resource name and the resource number identifier. For example, the mapping between the aforementioned "ic_wp_amber_fort" and "0x7f080698" is established.
[0091] It should be noted that in the implementation of the present disclosure, the electronic device can create a method class to generate a mapping between the resource name and the resource number identifier of the resource to be cached, and the method of establishing the mapping can adopt the class method supported by the operating system in the electronic device or the third-party library function, and the embodiments of the present disclosure do not limit this. Exemplarily, the electronic device can cache the mapping between the resource name and the resource number identifier based on the TreeMap method in the Android operating system.
[0092] It can be understood that in the embodiments of the present disclosure, the electronic device caches the mapping between the resource name and the resource number identifier corresponding to each resource for resource invocation. On the one hand, only caching the necessary information can reduce the caching time and the memory occupation of the cache, thereby improving the performance of resource invocation; on the other hand, when caching, caching the mapping relationship also helps to quickly find the resource number identifier based on the resource name when invoking the resource, so it can also improve the speed of resource invocation.
[0093] In some embodiments, during the running period of the code, for each resource to be cached, caching the mapping between the resource name and the resource number identifier includes:
[0094] During the running period of the code, for each resource to be cached, cache the mapping between the resource name and the resource number identifier based on a hash table.
[0095] In the embodiments of the present disclosure, the electronic device caches the mapping in the form of a hash table. As mentioned above, the electronic device can create a method class to generate a mapping between the resource name and the resource number identifier of the resource to be cached. In the embodiments of the present disclosure, taking the Android system as an example, the electronic device can create a cache implementation class through javapoet, such as the AiWatermarkResources class. This class includes an init method, which is used to generate a mapping between the resource name and the resource number identifier based on HashMap.
[0096] For example, the electronic device creates a HashMap container in the init method: mResources = new HashMap<>(16), and saves the resource information of the resource to be cached into this container through the put method. For example, the resource information of a certain resource is cached as follows: mResources.put("ic_wp_amber_fort", R.drawable.ic_wp_amber_fort). Among them, "ic_wp_amber_fort" is the resource name, and R.drawable.ic_wp_amber_fort is the resource number identifier returned based on the R class method, corresponding to the aforementioned "0x7f080698".
[0097] It should be noted that in the embodiments of the present disclosure, since the electronic device has obtained the resource information of the resources to be cached during the compilation period of the code, and the electronic device knows the number of resources to be cached, when the electronic device creates a HashMap container, it can create the size of the container according to the known number of resources to be cached. For example, in the above "new HashMap<>(16)", 16 is a value slightly larger than the number of resources to be cached.
[0098] It can be understood that in the embodiments of the present disclosure, based on the mapping between the resource name and the resource number identifier cached for each resource, on the one hand, since the hash table has a faster query speed compared to other mapping methods, it can improve the speed of subsequent resource calls; on the other hand, since the hash table can customize the container size, the electronic device can create the container size according to the known number of resources to be cached, so it can reduce the waste of memory, which is beneficial to the performance of code operation.
[0099] In some embodiments, the method further includes:
[0100] Obtain the resource name of the target resource to be called;
[0101] The calling of the resources based on the mapping between the resource name and the resource number identifier corresponding to each resource after caching includes:
[0102] Based on the mapping between the resource name and the resource number identifier corresponding to each resource after caching, determine the resource number identifier corresponding to the resource name of the target resource;
[0103] Implement the calling of the target resource based on the resource number identifier of the target resource.
[0104] In the embodiments of the present disclosure, when the electronic device calls resources based on the resource information of the resources to be cached, as described above, it is necessary to obtain the resource number identifier to call the resources. For this, in the embodiments of the present disclosure, the electronic device obtains the resource name of the target resource to be called, and based on the mapping between the resource name and the resource number identifier corresponding to each resource after caching, determines the resource number identifier corresponding to the resource name of the target resource.
[0105] It can be understood that since the method of determining the resource number identifier corresponding to the resource name of the target resource based on the mapping is a way of looking up a table, the calling of the resources can be quickly realized through this method.
[0106] In some embodiments, the determining the resource number identifier corresponding to the resource name of the target resource based on the mapping between the resource name and the resource number identifier corresponding to each resource after caching includes:
[0107] Instantiate the class method that maps each resource after calling the cache;
[0108] Use the resource name of the target resource as the input parameter of the class method and execute the instantiated class method;
[0109] Based on the execution result of the instantiated class method, determine the resource number identifier of the target resource.
[0110] In the embodiments of the present disclosure, the electronic device may also create a tool class that uses the cache, such as the ResourcesCacheUtils class. Through various methods included in this class, the cached resources can be obtained through reflection. Among them, this class includes a class method that maps each resource after calling the cache. The electronic device can implement the call of the resource based on this class method. Exemplarily, this class method may be:
[0111] public Integer getResourcesId(String resourceName){
[0112] return mResources.get(resourceName);
[0113] }
[0114] In the above class method, the input parameter is the resource name "resourceName", and the return value is "mResources.get(resourceName)", which represents the resource number identifier; among them, mResources refers to the aforementioned cached mapping.
[0115] Based on the above class method, it can be seen that the resource name of the target resource to be called needs to be passed in, and the corresponding resource number identifier can be returned based on the cached mapping. When the above class method is called, instantiation needs to be performed first. Exemplarily, instantiating this class method with the cache variable can be cache.getResourcesId(name). Based on the instantiated class method, the electronic device can obtain the execution result of the instantiated class method by passing in the resource name of the target resource.
[0116] It should be noted that in the embodiments of the present disclosure, if the resource information of the target resource exists in the cached mapping, the electronic device may determine the return value after executing the instantiated class method as the resource number identifier of the target resource.
[0117] It can be understood that in the embodiments of the present disclosure, the electronic device determines the resource number identifier corresponding to the resource name of the target resource by calling the class method that maps each resource after calling the cache, which is beneficial to the maintenance during code development, saves memory space, and improves the execution efficiency of the program.
[0118] It should be noted that, in the embodiment of the present disclosure, the tool class using the cache may also include a method class for obtaining a resource number identifier based on the resource type. Through this method class, after the resource type is passed in, the electronic device may return the resource number identifier belonging to that type of resource in the cache.
[0119] In some embodiments, determining the resource number identifier of the target resource based on the execution result of the instantiated class method includes:
[0120] In response to an execution result of the instantiated class method not being a preset value, determining the execution result as a resource number identifier of the target resource;
[0121] In response to the execution result of the instantiated class method being the preset value, searching for the resource number identifier of the target resource in the declaration file of the resource based on the resource name of the target resource.
[0122] In an embodiment of the present disclosure, the preset value may be "null". When the execution result of the instantiated class method is not empty, the electronic device directly determines the execution result as the resource number identifier of the target resource, which indicates that the resource exists in the cached mapping.
[0123] In the disclosed embodiment, if the execution result of the instantiated class method is null, it indicates that the resource does not exist in the cached mapping. In this case, the electronic device uses the original method to search the resource number identifier of the target resource in the resource declaration file based on the resource name of the target resource, for example, using the aforementioned getIdentifier method to determine the resource number identifier of the target resource from the declaration file.
[0124] It can be understood that in the embodiment of the present disclosure, the electronic device specifically determines the resource number identifier of the target resource based on whether the execution result of the instantiated class method is a preset value, so that the electronic device can increase the probability of successfully calling the target resource.
[0125] In some embodiments, the code includes a watermark resource loading code, and during the execution of the code, the resource information of the resource to be cached is cached, and the resource is called based on the cached resource information, including:
[0126] In response to the camera application being started and the camera mode being the watermark mode, running the watermark resource loading code and caching resource information of all watermark resources;
[0127] Based on the resource information of all watermark resources after caching, a resource list including all watermark resources is displayed;
[0128] The method further includes:
[0129] Determine a target watermark resource based on the displayed resource list;
[0130] In response to detecting a photographing instruction, capture an image;
[0131] Process the image based on the target watermark resource to obtain a target image with the watermark added.
[0132] In the embodiments of the present disclosure, the electronic device includes a camera application and supports the watermark mode. When taking a picture in the watermark mode, a watermark resource will be automatically added to the captured picture. For example, the watermark resource is a picture or text resource, and the above watermark resource is stored in the electronic device. In the embodiments of the present disclosure, after the electronic device starts the camera application, it can take pictures in the watermark mode based on the user's settings.
[0133] In the embodiments of the present disclosure, when the electronic device takes a picture in the watermark mode, it will start the watermark resource loading code. This code determines the resources to be cached during compilation. In this embodiment, the resources to be cached are all watermark resources, such as all the watermark resources indicated by the aforementioned "drawable" and "ic_w[pr]_.*". After compilation, during the running period of the watermark resource loading code, the electronic device can, for example, cache all watermark resources based on the aforementioned hash table mapping method for subsequent invocation of the watermark resources. In the embodiments of the present disclosure, when invoking all the cached watermark resources, for example, the electronic device can display the watermark resources based on the resource number identifiers of each watermark resource and display the watermark resources in a list form. For example, for picture resources, what is displayed in the list can be the picture content of the watermark resource or the name of the picture (such as cloud.jpg), etc.
[0134] In the embodiments of the present disclosure, based on the displayed resource list, the user of the electronic device can select the resources in the list. For example, the electronic device receives a voice instruction for selecting a target watermark resource or a touch selection instruction for the target watermark resource to determine the target watermark resource. Subsequently, after the electronic device detects a photographing instruction and captures an image, it can process the image based on the target watermark resource. For example, add the target watermark resource to the image to obtain a target image with the watermark resource after taking the picture.
[0135] It can be understood that in the embodiments of the present disclosure, when the photographing mode of the camera application of the electronic device is the watermark mode, the aforementioned resource invocation method is used to load the watermark resources, so that the electronic device can quickly add a watermark to the captured image to generate a target image, which can improve the photographing performance in the watermark mode and enhance the user experience.
