In a previous post about Gradle Flavors and Build Types, we mentioned that we can set different dependencies inside dependencies{} block by flavors, by build type or both combined. Below we will see an example for each situation.

By flavors

• <flavorName>Compile

  apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 23
      buildToolsVersion "23.0.3"
      defaultConfig {
          applicationId "com.example.diana.buildvariants"
          minSdkVersion 15
          targetSdkVersion 23
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
  
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
  
          qa {
              applicationIdSuffix ".qa"
  
              // signingConfigs as debug key needed. Otherwise, the app won't run and it will ask
              // you to sign the apk
              signingConfig signingConfigs.debug
          }
      }
  
      productFlavors {
          free {
              applicationId "com.example.myapp.free"
              versionName "1.0-free"
              minSdkVersion 23
          }
  
          paid {
              applicationId "com.example.myapp.paid"
              versionName "1.0-paid"
          }
      }
  }
  
  dependencies {
      paidCompile 'com.android.support:design:23.4.0'
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:23.4.0'
      compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha3'
      testCompile 'junit:junit:4.12'
      androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
      androidTestCompile 'com.android.support.test:runner:0.5'
      androidTestCompile 'com.android.support:support-annotations:23.4.0'
  }
  

By build type

• <buildTypeName>Compile>

  apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 23
      buildToolsVersion "23.0.3"
      defaultConfig {
          applicationId "com.example.diana.buildvariants"
          minSdkVersion 15
          targetSdkVersion 23
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
  
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
  
          qa {
              applicationIdSuffix ".qa"
  
              // signingConfigs as debug key needed. Otherwise, the app won't run and it will ask
              // you to sign the apk
              signingConfig signingConfigs.debug
          }
      }
  
      productFlavors {
          free {
              applicationId "com.example.myapp.free"
              versionName "1.0-free"
              minSdkVersion 23
          }
  
          paid {
              applicationId "com.example.myapp.paid"
              versionName "1.0-paid"
          }
      }
  }
  
  dependencies {
      qaCompile 'com.android.support:design:23.4.0'
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:23.4.0'
      compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha3'
      testCompile 'junit:junit:4.12'
      androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
      androidTestCompile 'com.android.support.test:runner:0.5'
      androidTestCompile 'com.android.support:support-annotations:23.4.0'
  }
  

By both flavor and build type

• <flavorName><BuildTypeName>Compile.
• In this case you have to define the custom compile in configurations{} block in order to be recognized in dependencies{} block.

  configurations {
    paidQaCompile
  }

  Final result:

  apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 23
      buildToolsVersion "23.0.3"
      defaultConfig {
          applicationId "com.example.diana.buildvariants"
          minSdkVersion 15
          targetSdkVersion 23
          versionCode 1
          versionName "1.0"
          testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
  
      buildTypes {
          release {
              minifyEnabled false
              proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
          }
  
          qa {
              applicationIdSuffix ".qa"
  
              // signingConfigs as debug key needed. Otherwise, the app won't run and it will ask
              // you to sign the apk
              signingConfig signingConfigs.debug
          }
      }
  
      productFlavors {
          free {
              applicationId "com.example.myapp.free"
              versionName "1.0-free"
              minSdkVersion 23
          }
  
          paid {
              applicationId "com.example.myapp.paid"
              versionName "1.0-paid"
          }
      }
  }
  configurations {
      paidQaCompile
  }
  
  dependencies {
      paidQaCompile 'com.android.support:design:23.4.0'
      compile fileTree(dir: 'libs', include: ['*.jar'])
      compile 'com.android.support:appcompat-v7:23.4.0'
      compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha3'
      testCompile 'junit:junit:4.12'
      androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
      androidTestCompile 'com.android.support.test:runner:0.5'
      androidTestCompile 'com.android.support:support-annotations:23.4.0'
  }
