当应用使用Firebase在Backgroud时，Android代码获取推送通知日志

Question

当我尝试在firebase中使用自定义数据发送通知时，我没有在后台收到通知

我的firebase服务代码是：

在on消息接收方法

    @Override 
public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.e("fcm", "received notification");
        if (remoteMessage == null)
            return;
        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0) {
            Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());
            try {
                int badge = Integer.parseInt(remoteMessage.getData().get("badge"));
                String message = remoteMessage.getData().get("message");
                String timestamp = remoteMessage.getData().get("timestamp");
                handleDataMessage(badge,message,timestamp);
                badgeStore = Integer.parseInt(remoteMessage.getData().get("badge"));
            } catch (Exception e) {
                Log.e(TAG, "Exception: " + e.getMessage());
            }
        }
    }

请在Menifest文件中注册您的firebase服务

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

在应用程序标签中添加这些行以设置自定义默认图标和自定义颜色：

<meta-data
    android:name="com.google.firebase.messaging.default_notification_icon"
    android:resource="@drawable/ic_stat_ic_notification" />
<meta-data
    android:name="com.google.firebase.messaging.default_notification_color"
    android:resource="@color/colorAccent" />
