我正在尝试“捕获”发送到应用程序的 firebase 云消息，当我收到（/单击）一个消息时，我想根据在 firebase 控制台中添加的“自定义数据”键/值执行某些操作。

我的代码现在看起来像这样：

MyFirebaseMessagingService：

package com.company.app;

import android.util.Log;

import androidx.annotation.NonNull;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

import java.util.Map;

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = "Notification";

    @Override
    public void onMessageReceived(@NonNull RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);

        Log.i(TAG, "Receiving notification...");
        for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) {
            String key = entry.getKey();
            String value = entry.getValue();
            Log.d(TAG, "key, " + key + " value " + value);
        }
    }
}

AndroidManifest.xml：

        ...

        <!-- Firebase notification -->
        <service
            android:name=".MyFirebaseMessagingService"
            android:exported="false">

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

    </application>

build.gradle（模块：应用程序）：

dependencies {

    //Google firebase
    implementation 'com.google.firebase:firebase-analytics:17.2.1'
    implementation 'com.google.firebase:firebase-messaging:20.0.1'

    ...

我的猜测是<service android:name=".MyFirebaseMessagingService" android:exported="false">没有被执行，但我不知道为什么。我没有收到任何错误。除此之外，我的通知工作没有任何问题。

如果有任何帮助，这里是控制台日志：

D/FA: Logging event (FE): notification_receive(_nr), 
Bundle[{
 ga_event_origin(_o)=fcm,
 message_device_time(_ndt)=0,
 message_type(_nmc)=display,
 message_name(_nmn)=B1 - TN18,
 message_time(_nmt)=1574177464,
 message_id(_nmid)=8950284200210511319}]

有任何想法吗？

编辑：相同的代码适用于其他空的应用程序

编辑 2：问题是由谷歌的 TWA LauncherActivity 引起的

编辑3：

public class LauncherActivityTWA extends AppCompatActivity {

private TwaLauncher mTwaLauncher;
...
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    this.mTwaLauncher.launch(getLaunchingUrl()); //this is causing the issue
}

编辑 4：现在我已经通过切换到 WebView 解决了这个问题，稍后我将尝试让它与 TWA 一起工作。我仍然认为这个问题是由 TWA 或与之相关的一些库引起的

onMessageReceived编辑 5：所以我找到了一种解决方法 - 如果您想同时继续使用 TWA 和 FCM，您将不得不只使用数据消息，即使应用程序在前台，通知消息似乎也不会触发

根据您的问题，我猜您正在接收数据消息 

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    if (remoteMessage == null)
        return;
    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
        handleNotification(remoteMessage.getNotification().getBody());
    }
    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        String title = "", body = "", type = "";
        Intent hIntent = new Intent(getApplicationContext(), HomePageActivity.class);
        try {
            for (Map.Entry<String, String> entry : remoteMessage.getData().entrySet()) 
               {
                String key = entry.getKey();
                String value = entry.getValue();
                CommonUtils.logThis(TAG, "key, " + key + " value " + value);
                switch (key) {
                    case "title":
                        title = entry.getValue();
                        break;
                    case "body":
                        body = entry.getValue();
                        break;
                    case "type":
                        type = entry.getValue().toLowerCase();
                        break;
                }
            }
            CommonUtils.logThis("jeev", "Type is : " + type);
            switch (type) {
                case "your_notification_type":
                    //write your code here
                    break;
            }
        } catch (Exception e) {
            CommonUtils.logThis(TAG, "Exception: " + e.getMessage());
        }
    }
}

仅当收到的消息是通知消息时才会出现此问题。即使使用 TWA，它也可以按预期处理数据消息。有关消息类型的更多信息在这里。

TL;DR：只有当应用程序处于前台时，数据消息才会触发甚至总是通知消息。

我不知道是什么导致了这个问题，但我已经在 GitHub 上创建了一个关于它的问题，所以也许它会在未来得到修复。
