In order to further explain the technical means and effects adopted by the present application, the following description clearly and completely describes the technical solution of the present application with reference to the accompanying drawings and preferred embodiments.
FIG. 1 shows a flowchart of a method for android platform duplicate file retrieval in one aspect of the subject application, where the method of an embodiment comprises:
s11, calculating the hash value of each file in the target file directory;
s12, comparing the hash values of the files two by two, and if the hash values of the two files are the same, determining that the two files are duplicate files;
s13 traverses each file under the target file directory to complete the retrieval of the duplicate files under the target file directory.
In the present application, the method is performed by a device 1, where the device 1 is a computer device and/or a cloud for application project development of an android platform. Wherein the computer device includes but is not limited to a personal computer, a notebook computer, an industrial computer, a network host, a single network server, a plurality of network server sets; the Cloud is made up of a large number of computers or web servers based on Cloud Computing (Cloud Computing), which is a type of distributed Computing, a virtual supercomputer consisting of a collection of loosely coupled computers.
The computer device and/or cloud are merely examples, and other existing or future devices and/or resource sharing platforms, as applicable to the present application, are also intended to be included within the scope of the present application and are hereby incorporated by reference.
All resources developed on the device 1 for the same application project for the android platform are typically stored under the same file directory.
In this embodiment, in said step S11, the device 1 traverses each file under the target file directory, including each file under each level of subdirectory (if any) under the target file directory, and calculates a hash value of each file.
Optionally, wherein the step S11 includes:
configuring a target file directory in a predefined building tool plug-in;
and calculating the hash value of each file in the target file directory by adopting a preset algorithm.
In an alternative embodiment, the device 1 employs a predefined building tool plug-in, which is the open source tool Gradle for android platform building application items provided by Google (Google). The device 1 constructs a newly developed application project through the Gradle, configures a file directory, and stores files required when the application project is constructed and files produced in the development process. The device 1 also configures a target file directory, where a file directory in which duplicate files may exist is configured as the target file directory, for example, a file directory in which files required for building an application project and files produced in a development process are stored is configured as the target file directory. The target file directory may include sub-file directories thereunder.
Before the application project is developed and the application program installation package is output, a preset algorithm can be adopted to calculate the hash value of each file in the target file directory.
In the application project construction and development process based on the android platform, a large number of picture files (such as png format picture files) are often used for background and other purposes, and the effect of screening out repeated picture files is more obvious for reducing the occupied space of an application program. Thus, the hash value for each png file under the target file directory may also be calculated for a specified type of file, such as a png type of file.
Optionally, wherein the preset algorithm is SHA1 algorithm.
The SHA1(Secure Hash Algorithm1, version 1 of the Secure Hash Algorithm) Algorithm may be used to calculate the Hash value of each file under the target file directory, where the SHA1 Hash value of each file is 20 bytes (160 bits).
Algorithms such as SHA256, MD5(Message-Digest Algorithm5, 5 th edition of Message Digest Algorithm) may also be used to calculate the hash value for each file under the target file directory.
Continuing in the embodiment, after the device 1 calculates the hash value of each file in the target file directory by using the preset algorithm, in step S12, the device 1 compares the hash values of the files two by two, and if the hash values of the two files are the same, it is determined that the two files are duplicate files, that is, the two files are completely the same. For example, if the value of SHA1 of file a in the target file directory is the same as the value of SHA1 of file B in the subdirectory of the target file directory, file a and file B are determined to be duplicate files.
Continuing with the embodiment, in step S13, the device 1 traverses each file in the target file directory, completes the hash value of the two-by-two comparison files between all the files, and completes the retrieval of the duplicate file in the target file directory.
Optionally, the method for android platform duplicate file retrieval further includes:
s14 (not shown) associating the hash value of each file with its storage path, and grouping each file associated with the storage path based on the hash value of the file;
s15 (not shown) outputs the packet in which the duplicate file exists.
In an alternative embodiment, after calculating the hash value of each file in the target file directory, the hash value of the obtained file may be associated with the storage path of the file, and each file associated with the storage path may be grouped based on the hash value of the file, for example, the file name including the storage path (or the full storage path information of the file) is stored in the group by using the hash value of the file or a group code uniquely corresponding to the hash value. After traversing each file in the target file directory, comparing the hash values of the files two by two, and searching all the duplicate files in the target file directory, outputting the packet with the duplicate files, for example, outputting the hash values of the duplicate files or the packet numbers corresponding to the hash values.
Optionally, the method further comprises:
s16 (not shown) deletes redundant files according to the output packet in which duplicate files exist.
The full storage path information of each repeated file corresponding to the hash value can be determined according to the output hash value with the repeated files or the grouping number corresponding to the hash value, and then the redundant files can be deleted after further analysis of repeated resources, so that the size of the storage space occupied by the application program is reduced. For example, if the packet corresponding to the output SHA1 value includes the full storage path information of the duplicate file a and the file B, the duplicate file a (or the file B) may be deleted according to the actual situation of the application program, and only the file B (or the file a) is reserved, thereby achieving the purpose of reducing the storage space occupied by the application program.
The Gradle supports languages such as Java, Groovy, and Scala. The following is part of the basic logic code of an application instance for computing SHA1 values written based on the Java language and grouping files associated with storage paths based on SHA1 values. The method based on the application can also be realized by adopting languages such as Groovy or Scala.

the second module 22 is configured to compare the hash values of the files two by two, and if the hash values of the two files are the same, determine that the two files are duplicate files;

In an optional embodiment, after the first module 21 of the apparatus calculates the hash value of each file in the target file directory, the fourth module 24 associates the obtained hash value of the file with the storage path of the file, and groups each file associated with the storage path based on the hash value of the file; the fifth module 25 then outputs the packet in which the duplicate file exists.
