应用程序清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.urvish.notificationdemo">
<uses-permission android:name="android.permission.INTERNET"/>

</application>MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FirebaseApp.initializeApp(this);
}MyFirebaseInstanceIdService.java
public class MyFirebaseInstanceIdService extends
FirebaseInstanceIdService {
@Override
public void onTokenRefresh() {
super.onTokenRefresh();
String token = FirebaseInstanceId.getInstance().getToken();
Log.d("MyToken",token);
}
}MyFirebaseMessagingService.java
public class MyFirebaseMessagingService extends
FirebaseMessagingService {
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
String title = remoteMessage.getNotification().getTitle();
String body = remoteMessage.getNotification().getBody();
Log.d("TAG", "onMessageReceived: " + title + ":" + body);
System.out.println("msg" + title + ":" + body);
}
}到目前为止，我检查了我的应用程序是否连接到了firebase。我最初得到了令牌。但是，我仍然没有收到来自firbase cloud的任何通知。我已经阅读了文档并遵循了教程。

我也遇到了同样的问题，我先取回了令牌，最后成功地收到了消息。希望这能有所帮助。
FirebaseInstanceId.getInstance().getInstanceId().addOnCompleteListener(new
OnCompleteListener<InstanceIdResult>() {
@Override
public void onComplete(@NonNull Task<InstanceIdResult> task) {
if (!task.isSuccessful()) {
return;
}
// Get new Instance ID token
String token = task.getResult().getToken();
// Log and toast
String msg = getString(R.string.msg_token_fmt, token);
Toast.makeText(Login.this, msg, Toast.LENGTH_SHORT).show();
}
