未收到通知Firebase

Question

我有一個問題，有時我的應用程序（后台）沒有收到通知。 該通知將出現后，我需要重新啟動應用程序，然后運行notification.php 。

我不知道即時消息處理通知數據消息是否錯誤。 但是我已經在notification.php文件中添加了click_action"=>".EventDetailsActivity" ，在EventDetailsActivity.java處理了意圖，並在AndroidManifest.xml處理了意圖intent-filter標記

<intent-filter>
            <action android:name=".EventDetailsActivity" />
            <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

我希望你們能幫助我解決這個問題。 預先謝謝你。

Answer 1

不要在json負載中使用notification鍵。 試試這個吧？

$field = array(
    'to' => $topic,
    'data' => array(
        'title' => $title,
        'body' => $message,
        'type' => $type,
        'id' => $id,
        'click_action' => '.EventDetailsActivity'
    ),
    'priority' => 'high'
);

原因是，當同時使用notification和data密鑰時，它被視為通知消息 。 通知消息僅在前台起作用。 這是android示例中的注釋 ：

消息有兩種類型：數據消息和通知消息。 無論應用程序是在前台還是在后台，都在onMessageReceived中處理數據消息。 數據消息是GCM傳統上使用的類型。 當應用程序在前台時，僅在onMessageReceived中在此處接收到通知消息。 當應用程序在后台運行時，將顯示自動生成的通知。 當用戶點擊通知時，他們將返回到應用程序。 同時包含通知和數據有效負載的消息被視為通知消息。 Firebase控制台始終發送通知消息。 有關更多信息，請參見： https : //firebase.google.com/docs/cloud-messaging/concept-options

殺死我的應用程序時，我也遇到了同樣的問題。 此代碼有助於解決此問題。

在Manifest.xml中添加接收者

<uses-permission android:name="android.permission.WAKE_LOCK" />
<receiver android:name=".OnBootBroadcastReceiver">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
</receiver>

OnBootBroadcastReceiver.class

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class OnBootBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent("com.examle.FirebaseMessagingReceiveService");
        i.setClass(context, FirebaseMessagingReceiveService.class);
        context.startService(i);
    }
}
