Failed to resolve com.google.android.gms play-services-auth:11.4.0

Question

I am trying to write code for Android FirebaseUI — Auth in my android project but from last two days, I am getting errors in my current code and don\'t know how to fix it. t

Answer 1

From Firebase doc:

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

Bottom position of this line not top (below apply plugin: 'com.android.application').

Answer 2

In my case I've turned on gradle offline mode that's why it could not find out cached files for that version play-service or can not resolve. When I turn it on back to online everything is ok now.

Android Studio ->> File ->> Gradle ->> offline ->> uncheck

Answer 3

Android studio 3.2 Please follow below steps.

1.Invalidate cache and restart option. File->Invalidate/Restart

2. delete .gradle folder.

It will sync libs in next launch.

Answer 4

Change your top level dependency gradle setting

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        mavenLocal()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
        mavenLocal()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Answer 5

In my case I already had the google() repository installed. I was unable to resolve the dependency until I rebooted Android Studio. My guess is it couldn't resolve due to some lingering proxy config from when I had Charles open earlier in the day.

Answer 6

add this in your project level gradle file

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