如何从产品口味上控制 multiDex 和 minifying?

How to control multiDex and minifying from product flavors?

我正在使用以下风格来改进 Android 5 及更高版本设备的调试版本:

productFlavors {
    // Define separate dev and prod product flavors.
    dev {
      // dev utilizes minSDKVersion = 21 to allow the Android gradle plugin
      // to pre-dex each module and produce an APK that can be tested on
      // Android Lollipop without time consuming dex merging processes.
      minSdkVersion 21
    }
    prod {
      // The actual minSdkVersion for the application.
      minSdkVersion 16
    }
  }

然而,并非我所有的设备都在 api 21+ 下运行,因此我想控制 multiDex 和缩小。例如:

  productFlavors {
    dev {
      minSdkVersion 21
      multiDexEnabled false
      minifyEnabled false
    }
    prod {
      minSdkVersion 16
      multiDexEnabled true
      minifyEnabled true
    }
  }

但这给了我:

Error:(44, 0) Could not find method minifyEnabled() for arguments [false] on ProductFlavor_Decorated

如何将这些属性组合在一起?

minifyEnabled() 属性 仅在 BuildType DSL object. While multiDexEnabled refers to ProductFlavor 对象中可用。所以如果你想组合这些属性,你必须在这两个对象中指定它。例如:

productFlavors {
    dev {
        minSdkVersion 21
        multiDexEnabled false
    }
    prod {
        minSdkVersion 16
        multiDexEnabled true
    }
}

buildTypes {
    debug {
        minifyEnabled false
    }
    release {
        minifyEnabled true
    }
}

对于调试构建,使用 devDebug 构建变体,对于发布 - prodRelease.

参考这里 [https://developer.android.com/studio/build/multidex.html#dev-build]:

android {
            defaultConfig {
                ...
                multiDexEnabled true
            }
            productFlavors {
                dev {
                    // Enable pre-dexing to produce an APK that can be tested on
                    // Android 5.0+ without the time-consuming DEX build processes.
                    minSdkVersion 21
                }
                prod {
                    // The actual minSdkVersion for the production version.
                    minSdkVersion 14
                }
            }
            buildTypes {
                release {
                    minifyEnabled true
                    proguardFiles getDefaultProguardFile('proguard-android.txt'),
                                                         'proguard-rules.pro'
                }
            }
        }
        dependencies {
            compile 'com.android.support:multidex:1.0.1'
        }
