change your dependency compile "com.android.support:cardview-v7:25.3.1 android" compile "com.android.support:recyclerview-v7:25.3.1 android" — KuLdip PaTel, Jul 14 '17 at 12:43
Starting from version 26 of support libraries, you should add to your buildscript dependencies `maven { url https://maven.google.com }`, read [here](https://developer.android.com/topic/libraries/support-library/setup.html#add-library) — MatPag, Jul 14 '17 at 12:53

For Android Studio 2.3.3 you must add in your **MODULE-LEVEL** build.gradle file the following: `repositories { maven { url 'maven.google.com'; } }`. It is not enough the similar addition in the **project-level** build.gradle. See my answer to a similar question:[http://stackoverflow.com/a/46467737/4866544](http://stackoverflow.com/a/46467737/4866544) — billst, Oct 24 '17 at 09:43
@MatPag man it doesn't work inside buildscript brackets. It has to be inside allprojects { repositories { maven { url "https://maven.google.com" } } } . Tested by me. I'm using Android Studio 2.3.3 — Hanako, Sep 03 '18 at 14:01
@GianGomen Usually it should be in both places. By default when you create a new project the `url "maven.google.com";` (now `google()`) is added in buildscript and allprojects — MatPag, Sep 03 '18 at 14:13

Starting from version 26 of support libraries make sure that the repositories section includes a maven section with the "https://maven.google.com" endpoint.

Something like;

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

Why this is not included in the default templates? It's my first time into android studio how am I supposed to know this? I guess now i know how, but it tooked me a lot of time – Mattia Pettenuzzo Oct 04 '17 at 14:38

My apologies, and _mea culpa_ - I did have it in the `buildscript` block. Many thanks for pointing me in the direction of what I couldn't see.

This is how I have it working.

Add maven { url "https://maven.google.com" } as @Gabriele_Mariotti suggests above.

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

Then on the build.gradle file inside the App folder add

compileSdkVersion 26
buildToolsVersion "25.0.3"
defaultConfig {
    applicationId "com.xxx.yyy"
    minSdkVersion 16
    targetSdkVersion 26
}

Then on the dependencies use

dependencies {
    compile 'com.android.support:appcompat-v7:26.0.1'
    compile 'com.android.support:design:26.0.1'
    compile 'com.google.android.gms:play-services-maps:11.0.4'
    compile 'com.google.android.gms:play-services-location:11.0.4'
    compile 'com.mcxiaoke.volley:library-aar:1.0.0'
    compile 'com.android.support:cardview-v7:26.0.1'
}

If you are using Android Studio 3.0 or above make sure your project build.gradle should have content similar to-

buildscript {                 
    repositories {
        google()  // add google() before jcenter()
        jcenter()
    }
    dependencies {            
        classpath 'com.android.tools.build:gradle:3.0.1'

    }
}

allprojects {
    repositories {
        google()  // add google() before jcenter()
        jcenter()
    }
}

And for below Android Studio 3.0 and starting from support libraries 26.+ your project build.gradle must look like this-

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

Note- position really matters add google() before jcenter()

I face the same problem while I have updated my SDK and Android studio version(3.0 beta). I have solved this problem going through this tutorial. In this they told us to update are build configuration file like

android {

   buildToolsVersion '26.0.0'
   defaultConfig {
   targetSdkVersion 26
  }
  ...
}

dependencies {
   compile 'com.android.support:appcompat-v7:26.0.0'
}

// REQUIRED: Google's new Maven repo is required for the latest
// support library that is compatible with Android 8.0
repositories {
   maven {
       url 'https://maven.google.com'
       // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
   }

Hope it will help you out.

in may case I found OneSignal changed their dependencies

so I changed it from

compile 'com.onesignal:OneSignal:[3.5.8, 3.99.99]'

to

compile 'com.onesignal:OneSignal:[3.5.8, 3.5.8]'

then it works, please check any unspecific dependency.

Add this to the project level build.gradle file and it should work fine.

allprojects {
    repositories {
        google() // this is to be added if there's something already.
        jcenter()
    }
}

Google's new Maven repo is required for the latest support library that is compatible with Android 8.0. Just update your Google's Maven repository like below:

To add them to your build, add maven.google.com to the Maven repositories in your module-level build.gradle file:

repositories {
    maven {
        url 'https://maven.google.com'
        // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
    }
}

Alternative you can update build.gradle file like this:

    repositories {
        jcenter()
        google()
    }

Then add the desired library to your dependencies block. For example, the cardview library looks like this:

dependencies {
    compile 'com.android.support:cardview-v7:26.1.0'
}

Add gradle-4.1-rc-1-all in gradle-wrapper.properties.

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-rc-1-all.zip

Then add google() in the top-level build.gradle

Simply change the build-version from compile 'com.android.support:appcompat-v7:26.0.0'

to

compile 'com.android.support:appcompat-v7:26.0.0-alpha1'

Use compile 'com.android.support:cardview-v7:25.4.0'
If you want version 26 you should use compile 'com.android.support:cardview-v7:26.0.0-beta2', because it is beta for now

When you sync this dependency to the android studio:

 implementation 'com.android.support:cardview-v7:26.0.1-alpha1'

Then, Sync the Gradle with Project Files. It will say, (Suppose if you are working on new ones like androidx) obviously, it will show error on the dependency.

For that you can go to the File menu and click on the invalidate/restart the code. It will resolve itself and the application will restart without any error.
