Product Flavors

在 build.gradle 配置多个 Flavor

在 app/build.gradle 文件中配置：

android {flavorDimensions "default"productFlavors {dev {dimension "default"applicationIdSuffix ".dev"versionNameSuffix "-dev"buildConfigField "String", "BASE_URL", "\"https://api-dev.example.com/\""buildConfigField "String", "AUTH_URL", "\"https://auth-dev.example.com/\""}staging {dimension "default"applicationIdSuffix ".staging"versionNameSuffix "-staging"buildConfigField "String", "BASE_URL", "\"https://api-staging.example.com/\""buildConfigField "String", "AUTH_URL", "\"https://auth-staging.example.com/\""}prod {dimension "default"buildConfigField "String", "BASE_URL", "\"https://api.example.com/\""buildConfigField "String", "AUTH_URL", "\"https://auth.example.com/\""}}
}

在 Java 代码中使用 BuildConfig

public class ApiConfig {public static final String BASE_URL = BuildConfig.BASE_URL;public static final String AUTH_URL = BuildConfig.AUTH_URL;
}

在 Android Studio 选择不同环境

在 Build Variants 选择：

• devDebug
• stagingDebug
• prodRelease

这样就可以使用不同的 API 地址了。
