android - 添加 FirebaseUI 依赖项后同步失败

Question

在build.gradle(app)依赖中:

compile 'com.google.firebase:firebase-database:11.0.4'
compile 'com.google.firebase:firebase-auth:11.0.4'

This is the line that causes failure (without this line, it syncs without any problems)

compile 'com.firebaseui:firebase-ui-auth:2.1.1'

错误信息:

Failed to resolve: com.android.support:customtabs:25.4.0
Failed to resolve: com.android.support.constraint:constraint-layout:1.1.0-beta1
Failed to resolve: com.android.support:design:25.4.0
Failed to resolve: com.android.support:cardview-v7:25.4.0

Answer 1

我建议使用本指南解决 firebase-ui-auth 依赖错误:Firebase UI Auth

其次，为了解决项目中com.android.support:的依赖错误，

转到项目级别 build.gradle 并检查它是否看起来完全像这样:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}
