推送通知后的简单推送器错误：java.lang.NoClassDefFoundError

Question

我只是创建了一个简单的代码

我用 kotlin 制作了一个 android 应用程序我添加此代码：

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        PushNotifications.start(getApplicationContext(), "my_id")
        PushNotifications.addDeviceInterest("hello")
    }

这是我在终端推送的通知

curl -H "Content-Type: application/json"
  -H "Authorization: Bearer xxxxxxxx"
    -X POST "https://my_id.pushnotifications.pusher.com/publish_api/v1/instances/my_id/publishes"
      -d '{"interests":["hello"],"fcm":{"notification":{"title":"Hello","body":"Hello, world!"}}}'
{"publishId":"pubid-myid"}

当我尝试在终端上推送通知时，我的应用程序强制关闭

这是我的错误信息

我的依赖项：

 implementation 'com.google.firebase:firebase-analytics:17.2.0'
    implementation 'com.pusher:push-notifications-android:1.4.3'

您还需要将以下 firebase 消息添加到您的依赖项中：

implementation 'com.google.firebase:firebase-messaging:18.0.0'
