android - onMessageReceived() 在应用程序处于前台时不被调用

Question

我正在使用以下代码接收通过 firebase 控制台发送的 fcm 消息，但从未调用此函数。相反，当应用程序处于后台时，我能够在我的启动器类中接收消息，但是当应用程序处于前台时，我无法获取它。

public class MyFirebaseMessagingService extends FirebaseMessagingService {

private static final String TAG = "MyFirebaseMsgService";
String message="";
Map<String, String> m1;

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    //Displaying data in log
    //It is optional
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
    System.out.println("---------------------");

    message = remoteMessage.getNotification().getTitle();
    m1= remoteMessage.getData();
    System.out.println("=============="+m1);
    System.out.println("=============="+m1.get("url"));

    //Calling method to generate notification
    //sendNotification(remoteMessage.getNotification().getBody());
    //sendNotification_test(message);
   createNotification(m1,remoteMessage.getNotification().getBody());
}


private void createNotification(Map<String,String> payload, String title){

    Intent intent = new Intent(this, LoginActivity.class);


    intent.putExtra("url",payload.get("url"));
    intent.putExtra("package",payload.get("package"));
    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.mipmap.ic_launcher)
            .setContentTitle("FCM Message")
            .setContentText(title)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

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

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}

list

我将服务声明放在 list 中的应用程序标签之外:

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".LoginActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

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

        <service
            android:name="com.example.pranshusrivastav.fcmtest.MyFirebaseInstanceIDService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
            </intent-filter>
        </service>
    </application>

这成功了!!
