Description
Technical Field
The invention relates to the field of Android platform communication, in particular to a device and a method for two-by-two communication of software modules under an Android platform.
Background
In the software development process, development is often performed using a modular method. The modular development is a method of modern software development for decomposing complex systems into better manageable subsystems, each decomposed subsystem being referred to as a module, each module being independently developable. When the modules are required to be combined to form a complex system, the modules communicate and transfer information through communication.
Existing modular communication systems typically do the following:
1. all modules rely on a basic module, and communication before the module transmits data via the relevant protocol defined by the basic module.
2. The communication between the modules adopts a certain serialization mechanism (including but not limited to Json, seriability, parcelability and pb) to serialize the data transmission module which needs to be communicated, and the corresponding module needs to deserialize after receiving the corresponding data
3. Communication data is transmitted to the corresponding modules in a global communication mode through a global communication mechanism (including but not limited to global broadcasting, local broadcasting, eventbus) and the like
In the first method, all modules depend on a common module, so that the common module has the problems of high expansion speed, poor system maintainability, low development efficiency and the like.
The second method may result in reduced communication efficiency due to the use of a serialized communication mechanism.
The third method adopts a global communication mechanism, which results in the problems of poor system maintainability, low development efficiency and the like.
Thus, there is an urgent need for a comprehensive communication device to overcome the above-mentioned drawbacks.
Disclosure of Invention
In view of the above, the present invention aims to provide a modular communication device and method under an Android platform.
In order to achieve the above purpose, the present invention adopts the following technical scheme: the modularized communication device under the Android platform comprises at least two modules with communication requirements, a compiler and an intermediate code integrator, wherein the intermediate code integrator is used for integrating the respective intermediate codes of the two parties with the communication requirements to generate intermediate codes capable of being linked through compiling;
the module with communication requirement is provided with a module communication interface and a module dependent interface besides the module function code, the module function code defines the operation steps for completing the module function, and the module communication interface is matched with the module dependent interface of the other module in communication to transfer the dependent relationship to the module.
Further, the generation mode of the module dependent interface is as follows: and copying the communication related codes of the relied modules to a communication directory automatically generated by the device at the compiling period in the development stage.
Further, a plurality of module dependent interfaces can be provided for transferring the dependent relationship of the opposite module in different communications to the present module.
Further, the module dependency interface provides dependency transfer only for a particular one of the modules.
Further, the intermediate code integrator integrates the intermediate codes by searching and deleting the intermediate codes repeatedly relied on in the two modules of the two communication parties, so as to generate the intermediate codes capable of being connected through compiling.
Further, the communication device also comprises a custom compiler, wherein the custom compiler is used for directly deleting the repeated dependent codes in the process of generating the intermediate codes.
The invention also provides a modularized communication method under the Android platform, which comprises the following steps:
s1: splitting the dependent module into two parts, namely function realization and module communication;
s2: generating an intermediate code according to codes of two modules and a relied module of two communication parties;
s3: checking the intermediate codes generated by the two modules of the two communication parties and the dependent module, analyzing repeated dependent codes, deleting the repeated dependent codes, and generating integrated intermediate codes;
s4: and executing further compiling links on the integrated codes to generate a final library file or an executable file.
Further, the step S3 includes the following steps:
s31: whether the compiling environment masks the class file of the sourceFile is resolved, if not, the step S32 is executed, otherwise, the step S35 is skipped;
s32: reading attributes corresponding to the sourceFile to find the source file name corresponding to the class file;
s33: summarizing the repeatedly defined class files in all the modules which can be communicated pairwise;
s34: deleting the redefined class file and ending integration after storing the integrated intermediate code;
s35: scanning all class files;
s36: finding out class files matched with and retaining the api full path names;
s37: and deleting the class file matched with the full path name of the reserved api and ending integration after the integrated intermediate code is stored.
The method and the device solve the problem of conflict of codes generated during compiling among a plurality of modules with communication requirements. In theory, the number of the module communication is not limited, and the requirement of two-by-two bidirectional communication between any number of modules can be met. According to the modularized communication device, the module communication interface and the module dependence interface are arranged in the module, so that the problem that when two modules for communication depend on a certain third party module together, conflict can occur in the compiling process is solved, and the dependence relationship in module development is basically transparent to upper layer developers, so that the device has the advantages of high development efficiency and good maintainability compared with other communication schemes.

Detailed Description
As shown in fig. 1, in the prior art, if a module a needs to communicate with a module C, and the module a and the module C need to rely on a module B respectively during compiling, a phenomenon of using the module B simultaneously occurs during the stage of compiling an executable file by a compiler, which generates a conflict.
In order to avoid the occurrence of the above-mentioned collision, the dependency relationship is usually set and manually transferred. As shown in fig. 2, the module a is made dependent on the module C, while the module C is made dependent on the module B. In this way, the dependency relationship is transferred to the module A by the module C, and the conflict that the module B is used simultaneously in the compiling process is avoided. However, this scheme results in that when the module a is compiled each time, the module B and the module C are compiled again at the same time, which wastes compiling resources and reduces the communication efficiency between the modules.
In order to avoid serializing related data during communication between modules and improve communication efficiency, the invention provides a modularized communication device. The technical scheme of the invention is further described in detail below with reference to the accompanying drawings.
Example 1:
a modular communication device and method under an Android platform comprises at least two modules with communication requirements, a compiler and an intermediate code integrator. The modules may be divided into three parts, module function code, module communication interface and module dependent interface, respectively. The module function code is the main body of the module and is composed of main body source codes for realizing the module function; the module communication interface is regarded as an interface for the communication between the module and a specific other module and is used for information exchange and transmission; the module dependency interface is matched with a certain specific other module through the transfer dependency relationship, and the dependency relationship is transferred to the module dependency interface. When a plurality of modules with a dependency relationship need to perform two-by-two communication, corresponding communication interfaces and module dependency interfaces need to be respectively established according to the communication relationship.
As shown in fig. 3, it is assumed that modules a and C depend on module B, respectively. When the module A and the module C communicate, the module B needs to be split into two parts, namely a function implementation part and a module communication part. And simultaneously, copying the module communication related codes of the module B to a modular communication directory defined by the device. Since the device automatically generates the relevant directory in the compiling period, the problem of no path recognition is avoided.
Since the development is performed under the Android platform, the source codes in A, B, C modules are compiled by using a Java compiler to generate intermediate codes, namely class files.
And sending the generated 3 parts of intermediate codes into an intermediate code integrator, and judging whether the class file of the sourceFile is subjected to shielding setting by the intermediate code integrator. If no shielding setting is available, reading attributes corresponding to the sourceFiles to find out source file names corresponding to class files, and summarizing and deleting the class files repeatedly defined in the three modules. And if the shielding setting is carried out, scanning all class files, finding out the class files which are matched with and reserved with the api full-path name, and deleting.
In this embodiment, a typical structure of class is as follows:
the core source code of the intermediate code integrator operation is as follows:
after the integrated intermediate codes are obtained, further compiling and linking are carried out on the integrated intermediate codes, and a final library file or an executable file is generated.
Example 2:
a modular communication device and method under an Android platform comprises at least two modules with communication requirements, a compiler and an intermediate code integrator. The modules may be divided into three parts, module function code, module communication interface and module dependent interface, respectively. The module function code is the main body of the module and is composed of main body source codes for realizing the module function; the module communication interface is regarded as an interface for the communication between the module and a specific other module and is used for information exchange and transmission; the module dependency interface is matched with a certain specific other module through the transfer dependency relationship, and the dependency relationship is transferred to the module dependency interface. When a plurality of modules with a dependency relationship need to perform two-by-two communication, corresponding communication interfaces and module dependency interfaces need to be respectively established according to the communication relationship.
When the device developer has the capability of developing a custom compiler, the custom compiler can also be developed, when three modules of the dependency relationship shown in fig. 3 are compiled, an intermediate file without repeated dependent codes is directly generated, the setting of the intermediate code integrator is omitted in the device, the structure of the device is simplified, and the device has stronger flexibility.
The above describes the modularized communication device and method under the Android platform provided by the invention in detail, and specific examples are applied to describe the principle and implementation of the invention, and the description of the above examples is only used for helping to understand the method and core idea of the invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope according to the ideas of the present invention, the present disclosure should not be construed as limiting the technical solution of the present invention.
