版本冲突firebase库

Question

我收到此错误:

请通过更新google-services插件的版本来修复版本冲突(有关最新版本的信息,请访问 https://bintray.com/android/android-tools/com.google.gms.google-services/)或将com.google.android.gms的版本更新为16.0.1.

我认为我得到的错误是由于实施,com.google.firebase:firebase-messaging:17.1.0因为如果我删除它,建立成功.但是在尝试com.google.android.gms用于消息传递的16.0.1版本时,我得到以下消息:

无法解决错误

我认为错误意味着com.google.firebase:firebase-messaging:16.0.1不可用.我的问题怎么解决？

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

Answer 1

在Android工作室中有2个buld gradle文件.

1. build.gradle(Project:ProjectName)
2. build.gradle(模块:App)

我没有升级com.google.firebase:firebase-messaging:17.1.0过,然后我编辑classpath 'com.google.gms:google-services:3.0.1'到classpath 'com.google.gms:google-services:4.0.1'在的build.gradle(项目:项目名)和它的作品.我终于可以升级到17.1.0.
