类“MyFirebaseMessagingService"不是抽象的，也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 中使用了 FirebaseMessagingService，但是当我运行项目时，它会给我以下错误:

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

MyFirebaseMessagingService"类不是抽象的，也没有实现抽象基类成员 public abstract fun zzd(p0: Intent!):在 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

有什么帮助吗?

推荐答案

如果您不使用任何其他播放服务，请将您的 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.

如果你是，降级到 12.0.1 将起作用.

if you are, downgrading to 12.0.1 will work.

请务必坚持播放服务 3.2.1，因为 3.3.0 仍然会导致 firebase-config 崩溃.

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