当应用程序处于前台时，Firebase onMessageReceived未被调用

Question

I have read much documents regarding firebase push notification behaviour clearly. I'm able to see notification on the system tray when my app is in background but not triggering onMessageReceivedcall back when app is in foreground. I can see the logs that the message is received on my app. I have tried calling with data payload and without data payload from app server. My app server is using php script to trigger the fcm apis. Following is the php script I'm using

  $url = 'https://fcm.googleapis.com/fcm/send';
  $fields = array(
            'registration_ids' => $registatoin_ids,
     'notification' => array( "title"=>$title, "body" => $notification_message ,"click_action"  => $click_action,'color' => "#74BCEE",'icon' => "school_logo"));
      $headers = array(
            'Authorization: key='xxxxxxxxx',
            'Content-Type: application/json'
        );

        // Open connection
        $ch = curl_init();

        //echo "here";exit;
        // Set the url, number of POST vars, POST data
        curl_setopt($ch, CURLOPT_URL, $url);

        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

        // Disabling SSL Certificate support temporarly
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

        // Execute post
        $result = curl_exec($ch);
        if ($result === FALSE) {
            //die('Curl failed: ' . curl_error($ch));
            curl_close($ch);
            return;

        }
        print_r($result);

Following are the services i'm using in my Android app

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

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

Answer 1

I had the same problem. My problem was that the <service></service> tags were outside the <application></application> tag in the manifest file. When I put in the <application></application> tag, the problem was solved.
