我收到有关GoogleSignIn的“未解决参考”
当前文件已设置:
settings.gradle
include ':app', ':signin:app'
项目gradle:
buildscript {
ext{
kotlin_version = '1.2.60'
lifecycle_version = '1.1.1'
}
repositories {
jcenter()
google()
mavenCentral()
maven {
url 'https://maven.fabric.io/public'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'
classpath 'com.google.gms:google-services:4.0.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'io.fabric.tools:gradle:1.25.4'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
jcenter()
google()
maven {
url 'https://maven.google.com/'
}
}
}
app gradle:
dependencies {
...
implementation 'com.google.android.gms:play-services-gcm:15.0.1'
...}
最后导入:
import com.google.android.gms.auth.api.signin.GoogleSignIn
我尝试重建Project,刷新Gradle Project和使缓存无效,但我仍然获得GoogleSignIn的未解决参考。 当我尝试将play-services-gcm: 15.0.1 '更改为play-services-gcm: 16.0.0 '(这是最新的Google帐户登录名)时,我收到错误:“无法解决:com.google.android.gms:play-services-gcm:16.0.0”。 安装存储库和同步项目会出现另一个错误“找不到依赖项com.google.android.gms:play-services-gcm:16.0.0”
Gradle版本4.4 Android插件版本3.1.4
答案 0 :(得分:2)
您不应在项目中实施仅用于身份验证服务的所有Google Play服务
Apk文件的大小将增加,因此请按以下方式替换依赖项
implementation 'com.google.android.gms:play-services-auth:16.0.0'
建议将google-services插件版本更新为4.0.2
