我正在尝试使用fcm发送推送通知。我还按照教程中给出的步骤添加了google-services.json文件。我可以在日志中看到类似这样的消息，但不能看到推送通知。
D/FA: Logging event (FE): notification_foreground(_nf), Bundle[{firebase_event_origin(_o)=fcm, firebase_screen_class(_sc)=HomeScreenActivityTeacher, firebase_screen_id(_si)=2539281733171888617, message_device_time(_ndt)=0, message_name(_nmn)=bvvbv, message_time(_nmt)=1537166124, message_id(_nmid)=4182752688187919772}]
V/FA: Connection attempt already in progress
D/FA: Connected to remote service
Firebase控制台显示已传递消息，但在移动设备或模拟器上看不到该通知。请帮助我
这是我的服务课程
