Failed To Resolve: Com.google.gms.google-services:15.0.1:

I have installed play services in sdk tools and added following libs though it shows the problem compile 'com.android.support:appcompat-v7:26.1.0' compile 'com.android.suppo

Solution 1:

Remove com.google.gms.google-services:15.0.1 from dependencies, that is a gradle file plugin not an dependency.

defmySupportVersion = "26.1.0"

dependencies {
    compile"com.android.support:appcompat-v7:$mySupportVersion"compile"com.android.support:design:$mySupportVersion"compile"com.android.support:cardview-v7:$mySupportVersion"compile'com.android.support.constraint:constraint-layout:1.0.2'compile'com.firebase:geofire-android:2.1.1'compile"com.google.android.gms:play-services-maps:15.0.1"compile"com.google.android.gms:play-services-drive:15.0.1"compile'com.github.bumptech.glide:glide:4.0.0'compile'com.github.jd-alexander:library:1.1.0'compile'com.paypal.sdk:paypal-android-sdk:2.15.3'
    testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

You should use def for flexibility when changing version.

Solution 2:

I think unchecking Offline work option may solve the problem. Check My Answer Here.

Solution 3:

A lot of problems can cause this issue:

1) Check if you have Maven/Google repository on your top level main build.grade (can be found on your project root folder):

allprojects {
    repositories {
        jcenter()
        google()
    }
}

2) Check if you have the correct library number on your module App build.grade (can be found on \app) :

https://developer.android.com/topic/libraries/support-library/packages

3) Check buildToolsVersion and targetSdkVersion on your module App build.grade (can be found on \app):

Sometimes it's not possible to download anything if buildToolsVersion is not set to the new version. Check this site: https://developer.android.com/studio/releases/build-tools

4) Check internet connection and firewall issues

This is so simple, but nobody checks...

5) Check if Android Studio is set to Offline Work:

File ->
Other Settings ->Default Settings -> 
Build, Execution, Deployment ->
Build Tools ->
Gradle -> Uncheck Offline Work

6) If nothing works, click on Android Studio "clean project" and then "invalidade cache/restart":

Build->Clean Project
File->Invalidade Cache/Restart

Good Luck!

Solution 4:

just change the play service version to 15.0.0 and sync the gradle
