android后台应用程序只有在firebase控制台触发后才能接收fcm

Question

我想在应用从最近的任务中滑出时推送通知 首先尝试我使用邮递员推送通知，但通知不显示。 第二次尝试我使用firebase控制台推送通知，并显示通知，然后我尝试使用邮递员推送并且它工作。 我的问题为什么如果我只使用邮递员推送它不起作用，但如果我使用firebase控制台触发然后使用邮递员它可以工作？如何在不从 Firebase 控制台触发的情况下推送？

这是我的安卓代码

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG = MyFirebaseMessagingService.class.getSimpleName();

@Override

    super.onNewToken(token);
    Log.d("TAG", "New token: " + token);
    storeRegIdInPref(token);
}

private void storeRegIdInPref(String token) {
    SharedPreferences sp = getApplicationContext().getSharedPreferences("FCMID", 0);
    SharedPreferences.Editor editor = sp.edit();
    editor.putString("regId", token);
    editor.commit();
}

这是我的邮递员代码

{
"data": {
    "message": "\"Henlo6\"",
    "notifid": 2020090001,
    "timestamp": "\"2020-09-29 17:45:22\"",
    "title": "\"Hai\"",
    "priority":"HIGH"
},
"time_to_live": 86400,
"to": "token"

}

我认为您可能已退出应用程序，因此消息服务已停止。如果你想在应用程序不运行的情况下接收通知，你应该在使用邮递员时添加“通知”部分。

{
    "notification": {
        "title":"",
        "body":""
    },
    "data": {
        "message": "\"Henlo6\"",
        "notifid": 2020090001,
        "timestamp": "\"2020-09-29 17:45:22\"",
        "title": "\"Hai\"",
        "priority":"HIGH"
    },
    "time_to_live": 86400,
    "to": "token"
}
