问题描述

尝试使用具有架构组件和Kotlin的Android Studio 3 Canary 5构建示例会给出此警告.

Trying to build a sample using Android Studio 3 Canary 5 with Architecture Components and Kotlin gives this warning.

有人可以告诉我原因吗?

Can anyone tell me the reason?

谢谢，谢谢

编辑#1: 这是Dan Lew前一段时间制作的一个样本

推荐答案

现在有一个Java 8注释处理器，拱形组件很稳定，因此请替换:

There is a Java 8 annotation processor now arch components are stable so replace:

"android.arch.lifecycle:compiler:${rootProject.archLifecycleVersion}"

使用

"android.arch.lifecycle:common-java8:1.0.0"
