firebase-messaging:9.4.0 错过了 GoogleApiAvailability

GoogleApiAvailability missed with firebase-messaging:9.4.0(firebase-messaging:9.4.0 错过了 GoogleApiAvailability)

问题描述

将依赖声明为

compile 'com.google.firebase:firebase-messaging:9.4.0'

我在活动的导入行中收到无法解析符号 GoogleApiAvailability"消息

I get "can not resolve symbol GoogleApiAvailability" message in the activity's import row

import com.google.android.gms.common.GoogleApiAvailability;

怎么了?

• 不是问题的重复:Google Play 服务已经在最新版本上

推荐答案

将此行添加到您的构建文件依赖项中:

Add this line to your build file dependencies:

compile 'com.google.android.gms:play-services-base:9.4.0'

play-services-base 是 Play 服务基础客户端库，列在 播放服务设置指南.

play-services-base is the Play Services base client library and is listed in the Play Services Setup Guide.
