Detailed Description
The invention will be further explained with reference to the drawings and the embodiments.
Example (b): with reference to figures 1-2 of the drawings,
a method for developing Andriod system application by deviating from a source code compiling environment comprises the following steps,
and S1, determining the position of the system application item needing to be separated from the source code compiling environment in the system source code directory, and analyzing the dependency relationship. The system source code is completely compiled once before step S1 is executed to obtain the library file used in the compilation process of the system application project.
And S2, creating an empty engineering main directory, and copying the source code of the system application project into the engineering main directory.
And S3, quoting the related dependent source codes and resources developed by the system application project, configuring the running environment, adjusting the compiling quoting sequence, and setting the quoting catalog of the related dependent source codes and resources.
And the configuration operation environment comprises that the frame.jar files in the system source code compiling environment are used as a base sdk on which the system application items depend, and the priority of the frame.jar files in the system source code compiling environment is set in the system application item compiling process. The setting of the related dependent source code and the reference catalog of the resource comprises configuring the corresponding source code and the corresponding resource catalog and managing through a gradle script. And configuring the corresponding source code and the resource directory comprises placing the engineering main directory in a root directory of the system source code, and specifying the source code and the resource reference directory by configuring a relative path. The relative path is configured through script attribute sourceSets. And adding a code and a resource dependence module according to the dependence relationship of the system application item, introducing the code and the resource dependence module independently as dependence, placing the dependence in a reference directory, and managing by using a gradle script. And configuring modules depended by the system application items into dependence in the script, determining a dependence form according to the original dependence relationship, and adjusting the dependence sequence according to the dependence form. The dependency forms include compile-time dependencies, run-time dependencies, and full-state dependencies.
And S4, the whole compiling is completed by trial compiling and processing after error reporting.
Specifically, the system application is different from the common application in that the required permission is higher, the code is coupled with a system source code part more, and the system level interface which depends on the code is more, but as long as an independent item can clearly determine the dependency relationship according to the mk file under the directory, the independent item can be independently extracted and compiled as an independent application, and the independent application is not dependent on the source code environment any more.
The first preparation is to compile the whole source code once, i.e. to ensure the source code is accurate and has no errors and omissions, and simultaneously generate a library file to be used in the system application compilation process by using full compilation, as shown in fig. 1. The method includes that a required library file is found in a directory corresponding to a source code, generally, the library file dependent on system application is compiled and then stored in out/target/common/obj/JAVA _ LIBRARIES, a corresponding class. Meanwhile, a large amount of system hidden APIs are often introduced into system applications, sdk used in common Android engineering often cannot ensure that compilation is passed, so that a frame.jar file compiled by a current system needs to be found in an out/target/common/obj/JAVA _ LIBRARIES/frame _ interfaces directory to serve as a basis sdk on which the system applications depend, the priority of the frame.jar file in the compiling process is specified, and relevant data references exist for a specific setting method for Android Studio script item dependency reference, and are not repeated herein.
Secondly, corresponding resources and code (source code) directories need to be configured, so that the gradle script can manage corresponding file contents. In order to synchronize source codes and benefit from the flexibility of the Android Studio compiling script, a source code directory can be placed in a root directory of an Android project, and a source code and a resource directory are specified by configuring a relative path, as shown in fig. 1, so that an original project structure is not changed, and the Android Studio can be compiled and passed, that is, a complete directory of a system applied to the source codes is provided under the root directory of the project, and each module and main project only refer to file contents under the directory through a configuration file to participate in compiling. This section is configured by the script attribute sourceSets, and the related content can be referred to official documents.
And because the related resource files referenced by the system application are complicated, other project or resource files with different package names can be referenced, and at this time, a project module is needed to be added and is independently used as a dependence introduction to place the resource files therein, and the resource file references of other package names are compiled by using the gradle.
And finally, configuring a module dependent on the main project into a dependency in a script, determining a dependency form according to mk of an original project, determining whether the dependency is dependent in compiling, dependent in running or dependent in a full state, adjusting a dependency sequence according to the criterion, ensuring that running is not mistaken after compiling, possibly causing resource file identification errors, code or source code reference errors and the like in the project, and solving the problems according to prompts.
According to the method, the android.mk of the system application module needing to be stripped from the system source code directory is determined, and the item dependence condition is known; establishing an Android Studio project according to the project dependence condition, removing irrelevant contents, establishing a main project and each module according to the original mk file, and copying source codes to a project main directory; the method comprises the following steps of quoting related dependence and source codes, configuring an operating environment, adjusting a compiling quoting sequence, and setting related source codes and a resource quoting catalog; and (4) trial compilation is carried out to eliminate module error report, and the whole compilation is completed after specific error report contents are processed. The invention is a new system application development process, which uses the modern IDE to make the system application as the common application can be compiled and debugged quickly, and is convenient for the developer to compile and debug the system application without affecting the original system source code structure and content. The system software customization development in the field of the current automobile cockpit has a great efficiency improvement effect, the system can be applied and installed in the vehicle machine system under the condition that the system is not upgraded, and the system is suitable for some fast repairing scenes without considering the risk and time consumption of the whole system upgrading.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all that should be covered by the claims of the present invention.
