我被卡在推送通知中。我正在处理旧版本代码。我已经对其进行了更新，并在应用程序 build.gradle 中添加firebase依赖项后。HEN应用程序在后台崩溃，以下错误。但是在前景中，我收到了通知。请帮我。构建等级在这里

Answer 1

您正在为 NotificationCompat.Builder (Context context)

使用弃用的构造函数

而是使用此构造函数：NotificationCompat.Builder (Context context, String channelId)

Answer 2

而是使用此。

Notification notification =
            new NotificationCompat.Builder(this, CHANNEL_ID)
                    .setContentTitle(getText(R.string.notification_title))
                    .setContentText("Waiting for internet connection to forward sold products while offline")
                    .setSmallIcon(R.drawable.ic_notification_orange)
                    .setContentIntent(pendingIntent)
                    .setTicker("Hello Benjie")
                    .build();
