- iOS/Objective-C 元类和类别
- objective-c - -1001 错误,当 NSURLSession 通过 httpproxy 和/etc/hosts
- java - 使用网络类获取 url 地址
- ios - 推送通知中不播放声音
对于推送通知,我正在使用 FCM。我在 VIVO V3 手机中遇到了一些问题。 相同的代码在其他设备(黑莓、华为、三星)中适用于以下所有场景我已经测试了 3 个场景;
前两个条件运行良好。只有第三个问题。当应用程序终止时我没有收到任何通知。
服务器端使用以下代码发送数据通知消息,
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data" : {
"title" : "Notification Title",
"body" : "Notification Message",
},
}
我的应用中正在使用以下代码,

我已经在黑莓、华为、三星设备上进行了测试。它运行良好。请帮助我。在此先感谢。
最佳答案
您需要在 onCreate() 中执行此操作。您需要启用自动启动管理器,因为某些设备不允许。
