Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the method for identifying an integrated SDK in an application according to a preferred embodiment of the present invention includes the following steps:
step S10, an application basic information table is newly built for storing the obtained application basic information, an application analysis result table is newly built for storing the application analysis result, and an SDK dictionary table is newly built for storing the identified SDK;
step S20, performing decompiling on the application in the application library through an application package decompiling tool, acquiring package names appearing in the component configuration in the information description file of the application program, and storing the package name result analyzed by each application into the application analysis result table;
s30, counting the times of the same package name among different applications, and sequencing all the same package names according to the repeated times;
step S40, judging the data with the occurrence frequency more than or equal to the preset frequency and the preset percentage before the occurrence frequency as the package name of the SDK, and storing the package name as the unique identifier of the SDK dictionary table into the SDK dictionary table;
and step S50, acquiring the use condition of different SDKs by the applications according to the occurrence times of the same package name among different applications.
Specifically, the SDK identification method includes: the packet names of different applications are analyzed (the packet names are unique and only represent the names of the apk files), if one packet name with high repetition rate appears in the analysis results of a plurality of different applications, the packet name is highly possibly SDK, and if one packet name appears only once, the packet name with the SDK cannot be determined, and the higher the repetition rate of the same packet name among the different applications (the more the SDK is integrated), the higher the identification rate is.
Firstly, a database is created, specifically: and newly building an application basic information table for storing the acquired application basic information, an application analysis result table for storing an application analysis result, and an SDK dictionary table for storing the identified SDK. The invention mainly achieves the purposes of automatically identifying the SDK information, establishing a relatively complete SDK dictionary base and reducing the labor cost by analyzing a large number of mobile applications.
Then, decompiling the applications in the application library by using an application package decompilation tool (for example, APKTool, which is an APK compilation tool provided by GOOGLE, and is capable of decompilating and decompiling the APK, and simultaneously installing a frame-res frame required by the decompilation system APK, cleaning a last decompilation folder, and the like), and obtaining a package name appearing in the component configuration in android.xml (an information description file of an application program, in which the package name of a suspected SDK can be taken), wherein android is an application manifest (manifest meaning manifest), one of which must be included in a root directory of each application, and the file name must be the same, the file includes configuration information of the APP, the system needs to run the code of the APP according to the content therein, and an interface is displayed to describe each component of the application, which is used for defining four large components. What we use most often is an Activity component, which needs to define the presentation form of the component (component name, topic, launch type), the operation that the component can respond to (e.g., some launch intention), etc.; and storing the packet name result analyzed by each application in an application analysis result table.
Finally, counting the occurrence times of the same package names among different applications, and sequencing all the same package names according to the repetition times; the occurrence frequency is more than or equal to 2 times (the same package name appears for 2 times in different applications, which can be regarded as that the package name belongs to the SDK, the specific judgment basis is that the package name can be configured by a user in real-time application), and the data of 80% of the occurrence frequency is judged as the package name of the SDK (namely the occurrence frequency is more than or equal to 2 times, the repeated times of all the same package names are sorted, the data of 80% of the first ranking is taken as the SDK to be stored in an SDK dictionary database) and is taken as the unique identifier of the SDK dictionary database to be stored in the SDK dictionary database; according to the number of times of the same package name appearing among different applications, the number of applications using different SDKs can be known.
Further, the usage ratio of each SDK in the mobile application is counted, so that the SDKs which are heavily used in the mobile application are known. Counting the integrated number ratio of each SDK in the mobile application, similarly counting the use ratio of each type of reference, for example, if the use ratio of the short video type application is the first one in this year, the integrated ratio statistics of the SDK may know that the integrated ratio of the SDK in the streaming video processing may be the first one, and counting the integrated ratio is to know the use conditions of different SDKs.
The invention achieves the purpose of automatically identifying the integrated SDK in the application by analyzing a large number of mobile applications, collects the SDK with higher use frequency of the Internet application and effectively reduces the cost of collecting the SDK data.
