我们正在为未启用 Playservices 的客户实施百度推送服务。
一切都很好，但我遇到了巨大的延误，长达一小时。我们位于欧洲，我正在欧洲三星 Galaxy S8 上进行测试。
推送通知是通过百度推送控制台发送的，因此没有可以延迟通知的中间服务器。
我注意到有一个名为:bdservice_v1. 我假设该服务负责接收通知并将其传递给主应用程序进程。即使应用程序被杀死，我如何确保保持此进程处于活动状态？
更新：
我现在正在重新审视这个问题并发现，如果满足以下条件，一切都很好。
- 应用程序已被卸载
- 设备已重新启动
- 应用程序已重新安装
- 执行
PushManager.startWork
我上面提到的延迟是由于PushManager.startWork在特定时间内执行（还没有弄清楚到底有多长）。我猜百度已经实现了某种排队，并在之后将错过的通知推送到设备PushManager.startWork。
在此期间我也多次联系百度支持，但没有收到任何回复。甚至没有自动回复！
