我有时我的应用程序(后台)收不到通知。我需要重新启动应用程序，然后在出现通知后运行notification.php。
我不知道im处理通知数据消息是否错误。但是我已经在notification.php文件中添加了click_action"=>".EventDetailsActivity"，在EventDetailsActivity.java处处理意图，在AndroidManifest.xml处intent-filter标签
<intent-filter>
<action android:name=".EventDetailsActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
我希望你们能帮我解决这个问题。提前谢谢你。

不要在 json 有效负载中使用notification键。试试这个？
$field = array(
'to' => $topic,
'data' => array(
'title' => $title,
'body' => $message,
'type' => $type,
'id' => $id,
'click_action' => '.EventDetailsActivity'
),
'priority' => 'high'
);
原因是，当同时使用notification和data密钥时，它被视为通知消息。通知消息仅在前台工作。这是安卓示例中的注释：
有两种类型的消息数据消息和通知消息。无论应用是在前台还是后台，数据消息都在 onMessageReceived 中处理。数据电文是传统上与GCM一起使用的类型。仅当应用处于前台时，才会在 onMessageReceived 中接收通知消息。当应用程序在后台运行时，将显示自动生成的通知。当用户点击通知时，它们将返回到应用。同时包含通知和数据负载的消息被视为通知消息。Firebase 控制台始终发送通知消息。有关更多信息，请参阅：https://firebase.google.com/docs/cloud-messaging/concept-options
请参阅此类似问题：当应用在 Firebase 后台运行时如何处理通知
当我杀死我的应用程序时，我遇到了同样的问题。此代码有助于 解决此问题。
在清单中添加接收器.xml
<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>
开机广播接收器.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);
}
}
我有一个类似的问题.阻止它发送到应用程序的是
