MyFirebaseMessagingService.onMessageReceived() does not work

Question

我正在尝试"捕捉"发送到应用程序的firebase云消息，当我收到(/点击(一条消息时，我想根据firebase控制台中添加的"自定义数据"键/值执行一些操作。

我现在的代码是这样的：

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。我没有犯任何错误。除此之外，我的通知工作没有任何问题。

如果有任何帮助的话，这是控制台日志：

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}]

有什么想法吗？

编辑：相同的代码在一个空的应用程序中工作

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，我稍后会尝试让它与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

编辑5：所以我找到了一种变通方法——如果你想同时使用TWA和FCM，你必须只使用数据消息，即使应用程序在前台中，通知消息似乎也不会触发onMessageReceived

根据您的问题，我可以猜测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());
}
}
}

Answer 4

只有当收到的消息是通知消息时，才会出现问题。它在处理数据消息时，甚至在处理TWA时也能正常工作。有关邮件类型的更多信息，请点击此处。

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。
