类'MyFirebaseMessagingService'不是抽象的，并且没有实现抽象基类成员public abstract fun zzd(p0:Intent！) [英] Class 'MyFirebaseMessagingService' is not abstract and does not implement abstract base class member public abstract fun zzd(p0: Intent!)

问题描述

这里我在Kotlin中使用过FirebaseMessagingService，但是当我运行项目时，它将出现以下错误:

Here I have used FirebaseMessagingService in Kotlin but when I run the project it will give me the following error:

"MyFirebaseMessagingService"类不是抽象类，并且未实现抽象基类成员.public abstract fun zzd(p0:Intent！):com.google.firebase.messaging.FirebaseMessagingService中定义的单元

Class 'MyFirebaseMessagingService' is not abstract and does not implement abstract base class member public abstract fun zzd(p0: Intent!): Unit defined in com.google.firebase.messaging.FirebaseMessagingService

有帮助吗?

推荐答案

如果您不使用任何其他播放服务，则将您的Firebase版本升级到15.0.2.

If you aren't using any other play services then upgrade your firebase version to 15.0.2.

如果您愿意，可以降级为12.0.1.

if you are, downgrading to 12.0.1 will work.

请确保坚持使用服务3.2.1，因为3.3.0仍会崩溃firebase-config.

Make sure to stick to play service 3.2.1 since 3.3.0 will still crash firebase-config.
