未收到GCM推送通知

我尝试使用this代码进行GCM推送通知。 在此发送通知中,我使用this。但它显示了像酷的消息!发送的消息已成功检查您的设备... 但我的设备未收到通知。

您应该使用FCM。见

1)将此行添加到build.gradle:
dependencies { compile 'com.google.firebase:firebase-messaging:9.8.0'}

2)将此服务添加到清单 <service android:name=".MyFirebaseInstanceIDService"> <intent-filter> <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> </intent-filter> </service>
3)将此类添加到项目中。我建议你保存你的FCM令牌:

public class MyInstanceIDListenerService extends FirebaseInstanceIdService {


@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d("FirebaseService", "Refreshed token: " + refreshedToken);

    SharedPreferences sharedPref = getSharedPreferences("YOUR_SETTING_NAME", Context.MODE_PRIVATE);
    //There are optional steps
    SharedPreferences.Editor editor = sharedPref.edit();
    editor.putString("token", refreshedToken);
    //notify the token update 
    editor.putBoolean("tokenUpdate",true);
    editor.commit();
    //You can send this token to your server (if you have)
    sendServer(refreshedToken)
    }
}

4)现在将您的应用注册到https://console.firebase.google.com/。这将生成一个JSON文件,您必须将其放在app文件夹中。

5)对于生成FCM消息,您有两种可能性:
5.1)使用默认的Firebase控制台:https://console.firebase.google.com/project/fantamanager-2017/notification/compose
5.2)构建您的服务器应用程序(如果您愿意,我可以向您发送我的Php服务器代码)

6)将此服务添加到您的Manifest.xml中

<service android:name="FcmBroadcastReceiver">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
</service>

创建一个可以拦截推送的类:

 public class MyFirebaseMessagingService extends FirebaseMessagingService {
    private static final ID_NOTIFICATION = ...
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

       String from,data;
       from=remoteMessage.getFrom());


        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
           data=remoteMessage.getNotification().getBody());
        }

        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated. See sendNotification method below.
        sendNotification(data);
    }



    private void sendNotification(String messageBody) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_stat_ic_notification)
                .setContentTitle("FCM Message")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(ID_NOTIFICATION, notificationBuilder.build());
    }
}

或者,如果您有自定义服务,请使用以下命令更改onMessageReceived函数的主体:

   Map data = message.getData();
    if (data.containsKey(YOUR_DATA_FIELD_1)) {
        String field1= data.get(YOUR_DATA_FIELD_1).toString();
        String field2= data.get(YOUR_DATA_FIELD_2).toString();
        ....
        sendNotification(field1,field2...);
        return;
    }

您尝试过部分代码还是整个代码?最后我看到,gcm的新应用程序已关闭。只有FCM可用。所以你需要按照他们的说法注册,在app中实现json文件并继续。如果您已经有一个实现了gcm的项目,并且您尝试了此代码的一部分,那么请检查该密钥是否正确并且您没有从该项目中复制它们的密钥。或者可能缺少清单文件中的某些元数据。
