如何在Android Studio中使用口味

Question

在我的应用程序中，我想在我的应用程序中使用调味料。我将以下代码添加到build.gradle文件中，但是在设备上运行应用程序时（单击AndroidStudio中的运行按钮）会显示错误的数据！我的口味代码：

defaultConfig {
    applicationId "com.app.app"
    minSdkVersion 17
    targetSdkVersion 29
    versionCode 13
    versionName "1.0.13"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
    multiDexEnabled true
    //Custom flavors
    flavorDimensions "default"
    productFlavors {
        appFlav2 {
            applicationId "com.app.app.myapp2"
            resValue "string", "app_name", "App name 2"
            resValue "string", "appDescription", "description info 2"
            manifestPlaceholders = [
                    appIcon: "@drawable/logo_niaz"
            ]
        }
        appFlav3 {
            applicationId "com.app.app.myapp3"
            resValue "string", "app_name", "App name 3"
            resValue "string", "appDescription", "description info 3"
            manifestPlaceholders = [
                    appIcon: "@drawable/logo_niaz"
            ]
        }
        appFlav {
            applicationId "com.app.app"
            resValue "string", "app_name", "App name"
            resValue "string", "appDescription", "description info"
            manifestPlaceholders = [
                    appIcon: "@drawable/launcher"
            ]
        }
    }
}

但是在设备上运行应用程序时，显示以下信息：appFlav3。但我的默认风格是appFlav！

我该如何解决？

Answer 1

您必须选择构建变体以运行各自的样式。要找到构建变体选项卡，请看下面的屏幕截图。

Answer 2

如果要使isDefault.set(true)为默认值，则应设置appFlav：

appFlav {
    isDefault.set(true)
    applicationId "com.app.app"
    resValue "string", "app_name", "App name"
    resValue "string", "appDescription", "description info"
    manifestPlaceholders = [
            appIcon: "@drawable/launcher"
    ]
}

进行此设置，然后转到Files / Invalidate Caches/Restart，您将看到appFlav面板中始终将Build Variants始终设置为默认值，无论您先前选择了哪种构建变体。
