在Android Studio中引用的apk从其他模块类 [英] In Android Studio refer to .apk classes from other module

问题描述

这个问题来源于这样的事实，我不是一个摇篮专家，我来自Eclipse中的Maven +背景。

This question stems from the fact that I am not a Gradle expert and I come from Eclipse + Maven background.

在Maven的，我可以参考我的apk的项目从另一个（一Robolectric分项目为实例），作为 Android的Maven的插件在推无论 .apk文件和（UN-dexed）的.jar 在我的本地库。

In Maven, I was able to refer to my apk project from another one (a Robolectric sub-project for instance), as the android-maven-plugin was pushing both .apk and (un-dexed) .jar in my local repository.

我怎样才能达到同样的Andr​​oid Studio中+摇篮？

How can I achieve the same in Android Studio + Gradle?

• 我尝试添加应用插件：Java的来我的应用程序的项目，但Java插件不与Android插件兼容



• 我试图建立我的Java插件应用程序的一个子模块只能与的build.gradle ，但R.java不产生这样的：

• I tried to add apply plugin: 'java' to my app project but the java plugin is not compatible with the android plugin.

• I tried to build a sub-module of my app with the java plugin only with build.gradle, but R.java is not generated this way:

sourceSets {
    main {
        java.srcDirs = parent.android.sourceSets.main.java.srcDirs
    }
} 

是否有任何其他方式做到这一点？

Is there any other way to do this?

EDIT4：发布解决方案

posted solution.

推荐答案

在我的编辑解决方案实际效果很好。我在此报告的解决方案。 当心，它硬codeS的类文件的路径，我无法找出如何使用其中的$ buildType（有没有办法？）

The solution in my edits actually works well. I report it as solution here. Watch out, it hard-codes the path for the class files, I wasn't able to find out how to use the $buildType in it (is there a way?)

def variantName = "debug" // init to debug

apply plugin: 'android'

android {
    ...
    applicationVariants.all { variant ->
        variantName = variant.name
        buildDebugJar.dependsOn variant.packageApplication
    }
}

// Builds the jar containing compiled .java files only (no resources).
task buildJar(type: Jar) {
    description 'Generates the jar file along with the apk.'
    from new File("$project.buildDir/classes/$variantName")
}

configurations {
    jarOfApk
    transitive = false
}

artifacts {
    jarOfApk buildJar
}

和转诊模块（S），将宣布一个新的依赖关系是这样的：

And the referring module(s), will declare a new dependency this way:

compile project(path: ':app', configuration: 'jarOfApk')
