Android studio 工程的 module 依赖关系图绘制 、 Android Module 依赖关系的可视化实现

整体步骤：

• 1、利用gradle脚本生成dot；

• 2、利用graphviz将dot可视化转为图片

利用gradle脚本生成dot

下载projectDependencyGraph.gradle脚本

下载 projectDependencyGraph.gradle ，放在项目根目录，

源码如下：

task projectDependencyGraph {doLast {def dot = new File(rootProject.buildDir, 'reports/dependency-graph/project.dot')dot.parentFile.mkdirs()dot.delete()dot << 'digraph {\n'dot << "  graph [label=\"${rootProject.name}\\n \",labelloc=t,fontsize=30,ranksep=1.4];\n"dot << '  node [style=filled, fillcolor="#bbbbbb"];\n'dot << '  rankdir=TB;\n'def rootProjects = []def queue = [rootProject]while (!queue.isEmpty()) {def project = queue.remove(0)rootProjects.add(project)queue.addAll(project.childProjects.values())}def projects = new LinkedHashSet<Project>()def dependencies = new LinkedHashMap<Tuple2<Project, Project>, List<String>>()def multiplatformProjects = []def jsProjects = []def androidProjects = []def javaProjects = []queue = [rootProject]while (!queue.isEmpty()) {def project = queue.remove(0)queue.addAll(project.childProjects.values())if (project.plugins.hasPlugin('org.jetbrains.kotlin.multiplatform')) {multiplatformProjects.add(project)}if (project.plugins.hasPlugin('org.jetbrains.kotlin.js')) {jsProjects.add(project)}if (project.plugins.hasPlugin('com.android.library') || project.plugins.hasPlugin('com.android.application')) {androidProjects.add(project)}if (project.plugins.hasPlugin('java-library') || project.plugins.hasPlugin('java')) {javaProjects.add(project)}project.configurations.all { config ->config.dependencies.withType(ProjectDependency).collect { it.dependencyProject }.each { dependency ->projects.add(project)projects.add(dependency)rootProjects.remove(dependency)def graphKey = new Tuple2<Project, Project>(project, dependency)def traits = dependencies.computeIfAbsent(graphKey) { new ArrayList<String>() }if (config.name.toLowerCase().endsWith('implementation')) {traits.add('style=dotted')}}}}projects = projects.sort { it.path }dot << '\n  # Projects\n\n'for (project in projects) {def traits = []if (rootProjects.contains(project)) {traits.add('shape=box')}if (multiplatformProjects.contains(project)) {traits.add('fillcolor="#ffd2b3"')} else if (jsProjects.contains(project)) {traits.add('fillcolor="#ffffba"')} else if (androidProjects.contains(project)) {traits.add('fillcolor="#baffc9"')} else if (javaProjects.contains(project)) {traits.add('fillcolor="#ffb3ba"')} else {traits.add('fillcolor="#eeeeee"')}dot << "  \"${project.path}\" [${traits.join(", ")}];\n"}dot << '\n  {rank = same;'for (project in projects) {if (rootProjects.contains(project)) {dot << " \"${project.path}\";"}}dot << '}\n'dot << '\n  # Dependencies\n\n'dependencies.forEach { key, traits ->dot << "  \"${key.first.path}\" -> \"${key.second.path}\""if (!traits.isEmpty()) {dot << " [${traits.join(", ")}]"}dot << '\n'}dot << '}\n'//        def p = 'dot -Tpng -O project.dot'.execute([], dot.parentFile)
//        p.waitFor()
//        if (p.exitValue() != 0) {
//            throw new RuntimeException(p.errorStream.text)
//        }
//
//        println("Project module dependency graph created at ${dot.absolutePath}.png")}
}

引用：

apply from: "${project.rootProject.file('projectDependencyGraph.gradle')}"

运行脚本 ：

gradlew projectDependencyGraph

根目录会生成 build\reports\dependency-graph\project.dot

执行完命令后，会生成对应的dot文件
dot 是图形描述语言，简单来说就是用来描述一个图片的

查看

网页打开 .dot在线预览，复制.dot内容进入，即可查看

利用graphviz将dot可视化转为图片

为了把 dot 文件转 png 图片，你的机器上需要安装 GraphvizDownload | Graphviz。这玩意就是把 dot 转 png 的工具。

使用graphviz命令生成图即可，如下：

dot .\pp.dot -T jpg -o 11.jpg

若电脑上已安装Graphviz，可把上面脚本注释部分打开，即可把dot文件直接生成图片。

把上面脚本注释部分打开，电脑上未安装Graphviz，会报错 ：

java.io.IOException:
Cannot run program “dot” (in directory “\build\reports\dependency-graph”):
CreateProcess error=2, 系统找不到指定的文件。

下载了Graphviz，命令行输入dot -V，若找不到命令需要配置环境变量。我这里是直接在path中添加bin目录即可。
