Firebase 处理推送通知（FCM），而应用程序处于后台/杀死-Android

我想要什么：我想要从Firebase控制台发送通知。当应用程序处于后台/kill时，当用户点击推送通知时，它可以转到特定活动。让我们称之为当前提供活动。同样的事情也应该发生，而应用程序将在前台

我的理解：来自firebase docs，当应用程序位于前台时，将在

MyFirebaseMessagingService

类的

onMessageReceived

方法中接收来自firebase控制台的推送通知。但是当应用程序处于后台/kill时，

MyFirebaseMessagingService

类的

onMessageReceived

方法将不会被调用

我想要的：当应用程序处于后台/kill&用户点击推送通知时，我想将用户重定向到特定活动（当前提供活动）

我试过了，但没有找到解决办法

我的代码如下

MyFirebaseMessagingService.java

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private final String TAG = "mk";

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

        Log.e(TAG, "Message Body: " + remoteMessage.getNotification().getBody());
    }
}

    public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private final String TAG = "mk";

    @Override
    public void onTokenRefresh() {

        String refreshedToken = FirebaseInstanceId.getInstance().getToken();

        Log.e(TAG, "MyFirebaseInstanceIDService Token: " + refreshedToken);
    }
}

    public class ActivityOne extends AppCompatActivity {

    private final String TAG = "mk";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_one);

        String refreshedToken = FirebaseInstanceId.getInstance().getToken();

        Intent intent = getIntent();

        if (intent != null && intent.getExtras() != null) {

            Bundle extras = intent.getExtras();

            for (String key : extras.keySet()) {
                Log.e(TAG, key + " : " + extras.get(key));
            }
        }

        Log.e(TAG, "Token: " + refreshedToken);

        //sendNotificationToPatner();
    }

    private void sendNotificationToPatner() {

        Log.e(TAG, "in sendNotificationToPatner: ");

        SendNotificationModel sendNotificationModel = new SendNotificationModel("check", "i miss you");

        RequestNotificaton requestNotificaton = new RequestNotificaton();
        requestNotificaton.setSendNotificationModel(sendNotificationModel);

提前感谢。

解决方案：

如果您正在从firebase控制台发送推送通知&您的应用程序处于后台或已被终止，则不会调用MyFirebaseMessagingService（firebase文档中未提及这一点）

如果您正在从firebase控制台发送推送通知，并且您的应用程序位于前台，则会调用MyFirebaseMessagingService

如果您正在从服务器（我指的是后端，即网站或基于web的仪表板）发送推送通知&您的应用程序位于后台、kill或前台，则会调用MyFirebaseMessagingService

嗯，我来这里是想找到一个不同问题的解决方案，但我可以半途而废地回答你的问题

如果您正在发送带有数据负载的通知，那么您可以检查特定额外内容的意图。例如，如果在您的控制台（firebase）中有一个带有某个值（“这是我的消息”）的键（“自定义消息”），如下图所示

您可以在您的启动活动中收听Intent的附加节目，可以是splashscreen或mainactivity

 Intent intent = getIntent(); 
    if (intent.getStringExtras("custom_message") != null) {
      //go to specific activity when notification is opened
    }
   else{
     //open open default launch activity 
    }

现在，我早些时候说过我会半回答你的问题。为什么？这是因为我不知道当通知没有数据负载时，您将如何实现这一点。希望这能帮助别人

@Maulik Dodia信息也非常有用。感谢

您可以根据应用程序状态检查数据的准确行为和来自FCM的纯通知。让我检查一下，尽管我已经检查过了。可能是我错过了什么。如果你能在这里的评论中指出我遗漏的东西，对其他开发人员也会更好。@Rakesh
