示例用法

本主题提供如何使用云眼灰度试验 Android SDK 评估灰度标帜、激活 A/B 测试或功能测试的简短代码示例。

建议修改

安装 SDK 后，将 Eyeofcloud 功能试验库导入代码，获取云眼灰度试验项目的数据文件，并实例化客户端。然后，可以使用客户端评估标帜规则，包括 A/B 测试和标帜传递。

此示例演示了以下每个概念的基本用法：

1. 使用 Decide 方法计算具有键的标帜。作为副作用，Decision函数还会向Eyeofcloud发送决策事件，以记录当前用户已暴露于试验。product_sort

2. 有条件地执行特征代码。有以下几种选择：

• 获取标帜启用状态，然后检查标帜上名为 的配置变量。SDK 会评估标帜规则，并确定用户所处的标帜变体，从而确定他们应该看到的排序方法变量。sort_method
• 获取标帜变体，然后运行“控制”或“处理”代码。

3. 使用事件跟踪跟踪名为 的事件。此转化事件衡量试验的影响。使用 Track Event 方法，购买会自动归因到我们做出决定的正在运行的 A/B 测试，SDK 会通过可自定义的事件调度程序向 Eyeofcloud 发送网络请求，以便我们可以将其计入结果页面。purchased
