Android Studio 3.0风味尺寸问题

升级到Studio Canary版本。我之前的Telegram Messenger项目中出现以下错误。

错误：所有风味现在必须属于命名的风味维度。没有将风味“ armv7”分配给风味尺寸。进一步了解https://d.android.com/r/tools/flavorDimensions-missing-error-message.html

我该怎么办？我已经看过该链接，但不知道该怎么办。我现在有3个构建变体，即release，debug和foss。

如果您确实不需要该机制，则只需在您的中指定一个随机的风味尺寸即可build.gradle：

android { 
    ...
    flavorDimensions "default"
    ...
}

有关更多信息，请参阅迁移指南

经过仔细阅读后，我自己解决了。解决方案是在build.gradle中添加以下行。

flavourDimensions“ versionCode”

android { 
       compileSdkVersion 24
       .....
       flavorDimensions "versionCode"
} 

在这里您可以解决此问题，您需要添加带有productFlavors名称的flavourDimension，还需要定义尺寸，请参见以下示例，有关更多信息，请参见 https://developer.android.com/studio/build/gradle-plugin- 3-0-0-migration.html

flavorDimensions 'yourAppName' //here defined dimensions
productFlavors {
    production {
        dimension 'yourAppName' //you just need to add this line
        //here you no need to write applicationIdSuffix because by default it will point to your app package which is also available inside manifest.xml file.

    }

    staging {
        dimension 'yourAppName' //added here also
        applicationIdSuffix ".staging"//(.staging) will be added after your default package name.
        //or you can also use applicationId="your_package_name.staging" instead of applicationIdSuffix but remember if you are using applicationId then You have to mention full package name.
        //versionNameSuffix "-staging"

    }

    develop {
        dimension 'yourAppName' //add here too
        applicationIdSuffix ".develop"
        //versionNameSuffix "-develop"

    }

如果您不想使用尺寸，则应使用此行

android { 
compileSdkVersion 24

...
flavorDimensions "default"
...
}

但是，如果要使用尺寸，则应首先声明尺寸名称，然后在此示例来自文档后使用该名称：

android {
...
buildTypes {
debug {...}
release {...}
}

  // Specifies the flavor dimensions you want to use. The order in which you
  // list each dimension determines its priority, from highest to lowest,
  // when Gradle merges variant sources and configurations. You must assign
  // each product flavor you configure to one of the flavor dimensions.
  flavorDimensions "api", "mode"

  productFlavors {
    demo {
  // Assigns this product flavor to the "mode" flavor dimension.
  dimension "mode"
  ...
}

full {
  dimension "mode"
  ...
}

// Configurations in the "api" product flavors override those in "mode"
// flavors and the defaultConfig block. Gradle determines the priority
// between flavor dimensions based on the order in which they appear next
// to the flavorDimensions property above--the first dimension has a higher
// priority than the second, and so on.
minApi24 {
  dimension "api"
  minSdkVersion 24
  // To ensure the target device receives the version of the app with
  // the highest compatible API level, assign version codes in increasing
  // value with API level. To learn more about assigning version codes to
  // support app updates and uploading to Google Play, read Multiple APK Support
  versionCode 30000 + android.defaultConfig.versionCode
  versionNameSuffix "-minApi24"
  ...
}

minApi23 {
  dimension "api"
  minSdkVersion 23
  versionCode 20000  + android.defaultConfig.versionCode
  versionNameSuffix "-minApi23"
  ...
}

minApi21 {
  dimension "api"
  minSdkVersion 21
  versionCode 10000  + android.defaultConfig.versionCode
  versionNameSuffix "-minApi21"
  ...
    }
  }
}
...

我在build.gradle中为我的应用程序使用了flavorDimensions（模块：app）

flavorDimensions "tier"

productFlavors {
    production {
        flavorDimensions "tier"
        //manifestPlaceholders = [appName: APP_NAME]
        //signingConfig signingConfigs.config
    }
    staging {
        flavorDimensions "tier"
        //manifestPlaceholders = [appName: APP_NAME_STAGING]
        //applicationIdSuffix ".staging"
        //versionNameSuffix "-staging"
        //signingConfig signingConfigs.config
    }
}

检查此链接以获取更多信息

// Specifies two flavor dimensions.
flavorDimensions "tier", "minApi"

productFlavors {
     free {
            // Assigns this product flavor to the "tier" flavor dimension. Specifying
            // this property is optional if you are using only one dimension.
            dimension "tier"
            ...
     }

     paid {
            dimension "tier"
            ...
     }

     minApi23 {
            dimension "minApi"
            ...
     }

     minApi18 {
            dimension "minApi"
            ...
     }
}

如果您具有简单的风格（免费/专业版，演示/完整版等），请添加到build.gradle文件中：

android {
...
flavorDimensions "version"
productFlavors {
        free{
            dimension "version"
            ...
            }
        pro{
            dimension "version"
            ...
            }
}

通过尺寸，您可以创建“风味中的风味”。阅读更多。
