具有自定义源集的Android的Gradle风格 - gradle文件应该是什么样的？

Question

我有一个旧的eclipse项目我已经进入android studio并设置使用flavour.它似乎工作正常,直到我开始尝试在我的口味之间使用不同的java文件.

我的项目设置如下:

ProjectRoot
+- acitonbarsherlock
+- facebook
+- myLib1
+- myProject
   +- src
      +- commonFiles
         +- flavor1
         +- flavor2
   +- res
      +- flavor1
      +- flavor2

myProject gradle文件android闭包的内部看起来像这样:

android {
compileSdkVersion 17
buildToolsVersion "18.0.1"

signingConfigs {
     ...
}

productFlavors {
    flavor2 {
    }
    flavor1 {
    }
}

sourceSets{
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src/commonFiles/java']
        resources.srcDirs = ['src/commonFiles/java']
        aidl.srcDirs = ['src/commonFiles/java']
        renderscript.srcDirs = ['src/commonFiles/java']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    flavor2 {
        manifest.srcFile 'AndroidManifest-flavor2.xml'
        res.srcDirs = ['res-flavor2', 'res']
        java.srcDirs = ['src/flavor2/java','src/commonFiles/java']
        resources.srcDirs = ['src/flavor2/java','src/commonFiles/java']
        aidl.srcDirs = ['src/flavor2/java','src/commonFiles/java']
        renderscript.srcDirs = ['src/flavor2/java','src/commonFiles/java']
    }

    flavor1 {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src/flavor1/java','src/commonFiles/java']
        resources.srcDirs = ['src/flavor1/java','src/commonFiles/java']
        aidl.srcDirs = ['src/flavor1/java','src/commonFiles/java']
        renderscript.srcDirs = ['src/flavor1/java','src/commonFiles/java']
        res.srcDirs = ['res-flavor1','res']
        assets.srcDirs = ['assets']
    }

    // Move the tests to tests/java, tests/res, etc...
    instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')

}

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}

}

我的设置像这样gradle抱怨无法找到我试图从flavor1或flavor2中的commonFiles继承的类.

从我在这里看到的各种其他主题,我看到其他人甚至没有定义源集,我觉得我在他们身上做的事情可能太多了.

有没有人以前尝试过这个并且知道如何正确配置它？

Answer 1

我认为你最好不要定义自定义sourceSets但使用默认的gradle配置.我曾经做过自定义源集,直到我意识到这些约定很方便.

你会想要这样的东西:

+ src
    + main // this is your common code
        + java 
        + res
    + flavor1
        + java
        + res
    + flavor2
        + java
        + res

然后你可以继续从你的.删除源集关闭 build.gradle

注意:对于gradle配置,合并或覆盖资源,而所有java代码都放在同一个类路径上.例如,AndroidManifest.xml每个flavor 的文件只需要与mainmanifest文件有所不同.例如,如果存在这样的文件,那么拥有一个资产ic_launcher会覆盖ic_launcherfrom main.但是,HomeActivity.java在两者中都有一个文件main并且风格不可能,并且会出现重复的文件错误.

如果您愿意,欢迎您使用自定义sourceSets和flavours(或buildTypes).

例如,您可以按如下方式在Gradle文件中设置它们: -

productFlavors {
    flavor2 {
    }
    flavor1 {
    }
}

sourceSets{
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src/commonFiles/java']
        resources.srcDirs = ['src/commonFiles/java']
        aidl.srcDirs = ['src/commonFiles/java']
        renderscript.srcDirs = ['src/commonFiles/java']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }
  flavor1 {
       java.srcDirs = ['src-flavor1'] 
       res.srcDirs = ['res-flavor1']
       ...
    }

}

这种方法对我有用。享受

sourceSets {
        main {
            manifest.srcFile 'src/AndroidManifest.xml'
            java.srcDirs = ['src/java']
            resources.srcDirs = ['srs/others']
            res.srcDirs = ['src/res']
            assets.srcDirs = ['src/assets']
            jniLibs.srcDirs = ['jniLibs']
        }
        development{
            res.srcDirs += ['development/src/res']
        }
        standford{
            res.srcDirs += ['standford/src/res']
        }

        commercial{
            res.srcDirs += ['commercial/src/res']
        }

    }
    productFlavors {
        development{
            flavorDimensions "default"
        }
        standford{
            flavorDimensions "default"
        }
        commercial{
            flavorDimensions "default"
        }
    }

这是我的Gradle的样子:

   productFlavors {
    // Still keeping the productFlavors closure in case we decide to add flavors later
    normal {
        applicationId 'com.akshat'
    }
    qa {
        applicationId 'com.akshat.qa'
    }
}

 sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
        jni.srcDirs = [] // Set empty since we use our own ndkBuild task
        jniLibs.srcDirs = ['libs']
    }

    normal {
        java.srcDirs = ['src_normal']
    }
    qa{
        java.srcDirs = ['src_qa']
    }

以下是我的目录结构:

MyApplication
    - res
    - libs
    - jni 
    - src
         -com/akshat/
    - src_qa
         - com/akshat/util/FlavorConst.java
    - src_normal
         - com/akshat/util/FlavorConst.java
