我正在尝试让 AWS Pinpoint 向我的 Android 应用程序发送通知。我在这里完成了设置测试说明：https ://aws-amplify.github.io/docs/android/push-notifications
我能够获取 Pinpoint 客户端设备令牌并使用 Pinpoint 测试消息控制台发送消息。发送消息后，我的日志中会出现以下堆栈跟踪：
2019-04-11 11:56:34.757 8880-9196/com.example E/EventRecorder: Unable to successfully deliver events to server. Events will be saved, error likely recoverable.Cognito Identity not configured

stacktrace 建议我需要“Cognito Identity”才能使消息传递工作，但我不希望该服务，因为我已经构建了用户管理/身份验证过程。
我该如何解决这个问题？
谢谢你。
