OnMessageReceived对Firebase通知完全没有响应

标签： android firebase firebase-cloud-messaging firebase-notifications

我一直在互联网上发现问题为什么Android Studio中的模拟器没有收到来自我的PHP backend_API或Firebase控制台的通知，但大多数都没有解决我的问题。有很多关于Firebase在前台/后台没有收到通知的问题。但我的问题是onMessageReceived根本没有被调用，我甚至没有在Firebase的任何情况下成功收到任何回复或通知，但我100％确定我可以从Firebase获得令牌。

我能够从PHP后端获得成功响应。但是再一次，Firebase从来没有任何通知！ 

{"multicast_id":5857046882374247095,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1490047410456686%14ffa3cf14ffa3cf"}]}

我使用各种方法在前景或背景上测试了大约50次。我也尝试过其他几个教程，他们只是无法对我工作。我已经使用断点测试onMessageReceived，在Android监视器上观察网络状态（0 kb / s flat =无响应），在网上搜索。没运气！！！ 我使用的代码基本上与我在Youtube上获得的教程100％相似，他的Android模拟器确实收到了通知，但不是我的相同代码。有人能帮帮我吗？我花了3天但仍无济于事。

FirebaseMessagingService.java 

public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService{

    private static final String TAG = "succcess";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {

        String title = remoteMessage.getData().get("title");
        String body = remoteMessage.getData().get("body");

        Log.i(TAG, title);

        showNotification(title, body);
    }

    private void showNotification(String title, String body) {

        Intent i = new Intent(this,MainActivity.class);
        i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_ONE_SHOT);

        NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setContentTitle(title)
                .setContentText(body)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setAutoCancel(true)
                .setContentIntent(pendingIntent);

        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

        manager.notify(0,builder.build());
    }


}

FirebaseInstanceIDService.java 

public final class FirebaseInstanceIdReceiver extends WakefulBroadcastReceiver {
    public FirebaseInstanceIdReceiver() {
    }

    public void onReceive(Context var1, Intent var2) {
        if(this.isOrderedBroadcast()) {
            this.setResultCode(500);
        }

        var2.setComponent((ComponentName)null);
        var2.setPackage(var1.getPackageName());
        if(VERSION.SDK_INT <= 18) {
            var2.removeCategory(var1.getPackageName());
        }

        String var3 = var2.getStringExtra("gcm.rawData64");
        if(var3 != null) {
            var2.putExtra("rawData", Base64.decode(var3, 0));
            var2.removeExtra("gcm.rawData64");
        }

        String var4 = null;
        String var5 = var2.getStringExtra("from");
        if(!"com.google.android.c2dm.intent.REGISTRATION".equals(var2.getAction()) && !"google.com/iid".equals(var5) && !"gcm.googleapis.com/refresh".equals(var5)) {
            if("com.google.android.c2dm.intent.RECEIVE".equals(var2.getAction())) {
                var4 = "com.google.firebase.MESSAGING_EVENT";
            } else {
                Log.d("FirebaseInstanceId", "Unexpected intent");
            }
        } else {
            var4 = "com.google.firebase.INSTANCE_ID_EVENT";
        }

        int var6 = -1;
        if(var4 != null) {
            var6 = this.zza(var1, var4, var2);
        }

        if(this.isOrderedBroadcast()) {
            this.setResultCode(var6);
        }

    }

    public int zza(Context var1, String var2, Intent var3) {
        return zzg.zzabT().zzb(var1, var2, var3);
    }
}

使用大学/公司网络与FCM合作时，您应参考documentation中的说明：

  

如果您的组织有防火墙限制进出互联网的流量，则需要将其配置为允许与FCM连接，以便Firebase云消息传递客户端应用程序接收邮件。要打开的端口是：5228,5229和5230.FCM通常仅使用5228，但有时使用5229和5230.FCM不提供特定的IP，因此您应该允许防火墙接受包含的所有IP地址的传出连接在Google的ASN 15169中列出的IP块中。

或者只是使用您自己的不阻止FCM的连接。
