How to define different dependencies for different product flavors

问题

I am converting one of my apps to Gradle and would like to use the new build flavor features to have a paid and a free ad based flavor.

I want only the ad based version to depend on the admob SDK.

My build file looks like this:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath \'com.android.tools.build:gradle:0.5.+\'
    }
}
apply plugin: \'android\'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 18
    buildToolsVersion \"18.0.1\"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 18
    }

    productFlavors {
        Pro {
            packageName \"de.janusz.journeyman.zinsrechner.pro\"
        }
        Free { 
            dependencies {

            }
        }
    }
}

dependencies {
    compile \'com.android.support:support-v4:18.0.+\'
    compile \'com.actionbarsherlock:actionbarsherlock:4.4.0@aar\'
    compile fileTree(dir: \'libs\', include: \'*.jar\')
}

Is there a way to configure the dependency in the free product flavor to have its own libs folder that is merged with the main libs folder that contains general libraries for both flavors?

If this is possible how would I define this folder?

回答1:

To define a flavor specific dependency you can use proCompile instead of compile in your dependency section. When you run gradle properties you get an overview of automatic created configurations.

The correct build file looks like this:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
    }
}
apply plugin: 'com.android.application'

repositories {
    mavenCentral()
}

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 22
    }

    productFlavors {
        pro {
            packageName "de.janusz.journeyman.zinsrechner.pro"
        }
        free { }
    }
}

dependencies {
    compile 'com.android.support:support-v4:22.2.0'
    freeCompile 'com.google.android.gms:play-services-ads:7.5.0'
}

Fast forward to mid-2018. You will need to add flavorDimensions.

android {
    ...
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    flavorDimensions "dimensionName"
    productFlavors {
        pro {
            dimension "dimensionName"
        }
        free {
            dimension "dimensionName"
        }
    }
}

dependencies {
    implementation 'com.android.support:support-v4:22.2.0'
    freeImplementation 'com.google.android.gms:play-services-ads:15.0.1'
}

Also, take note:

Configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'. It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

You need to manually add configuration for each flavor. Example

configurations {
    proCompile
    freeCompile
}

dependencies {
    compile 'com.parse.bolts:bolts-tasks:1.3.0'

    proCompile 'com.android.support:design:23.1.1'
    freeCompile 'com.parse:parse-android:1.12.0'
}

Edit: I recommend using one of the other techniques!

An alternative to the accepted answer is this:

    ext {
        flavorType = ""
    }


    gradle.startParameter.getTaskNames().each { task ->

        if(task.contains("flavor1")){
            flavorType = "flavor1"
        } else if (task.contains("flavor2")){
            flavorType = "flavor2"
        } else {
            flavorType = "flavor3"
        }

    }

 if(flavorType == 'flavor1' || flavorType == 'flavor2') {
        compile 'com.android.support:support-v4:18.0.+'
    }

回答5:

Simple:

dependencies {

    ....
    ....

    gradle.startParameter.getTaskNames().each { task ->
        if(task.contains("free")) {
             implementation 'com.google.android.gms:play-services-ads:17.2.0'
        }
    }

    ....
    ....
}

or just:

FreeImplementation 'com.google.android.gms:play-services-ads:17.2.0'
