Cannot install Support repository and sync project in Android Studio

Question

I am trying to use the support libraries of version 25.2.0 so I will be able to use the CameraKit library.

I have got the newest build tools downloaded:

and the support repository:

my gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.2'
    defaultConfig {
        applicationId "com.sample.myapp"
        minSdkVersion 21
        targetSdkVersion 25
        versionCode 1
        versionName "1.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
repositories {
    maven {
        url "https://jitpack.io"
    }
    mavenCentral()
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    testCompile 'junit:junit:4.12'

    // Google libraries
    compile 'com.android.support:appcompat-v7:25.2.0'
    compile 'com.android.support:design:25.2.0'
    compile 'com.android.support:support-v4:25.2.0'
    compile 'com.google.android.gms:play-services-vision:10.0.1'
    compile 'com.android.volley:volley:1.0.0'

    // Third party libraries
    compile 'com.flurgle:camerakit:0.9.17'

    compile 'com.android.support:recyclerview-v7:25.2.0'
    compile 'com.android.support:cardview-v7:25.2.0'
}

Problem: For each support-library I get the issue:

Failed to resolve com.android.support:cardview-v7:25.2.0

If I try to click on Install repository and sync project nothing happens.

I have followed that gradle file as an example. Were could be my mistake?

Solution 1

Try using the latest support library versions:

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:support-v4:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.google.android.gms:play-services-vision:10.2.1'
compile 'com.android.volley:volley:1.0.0'
// Third party libraries
compile 'com.flurgle:camerakit:0.9.17'

compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'

here is the detail Dependencies

EDIT

Use Google Maven Repository

To add them to your build, you need to first include Google's Maven repository in your top-level build.gradle file:

Project -- build.gradle (Not app build.gradle)

 allprojects {
    repositories {
        // If you're using a version of Gradle lower than 4.1, you must instead use:
        maven {
            url 'https://maven.google.com'
        }
        // An alternative URL is 'https://dl.google.com/dl/android/maven2/'

       jcenter()
    }
}

Solution 2

Previously the Android Support Library dependencies were downloaded from Android SDK Manager.

Now all the new versions are available from Google's Maven repository. In future all android libraries will be distributed through maven.google.com

So, by adding the below code to the repositories will build the project.

repositories {
    maven {
        url "https://maven.google.com"
    }
}

Solution 3

I had to add the following to my project level build.gradle. Then the button to install and worked.

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

Solution 4

Make sure to put it under allprojects! My mistake was to put it under buildscript.

DON'T DO THIS:

buildscript {
    repositories {
        jcenter()
         maven {
             url 'https://maven.google.com' //don't put it here
         }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
    }
}

BUT INSTEAD DO THIS:

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com' //put it here
        }
    }
}

I have applied the changes you suggest and get the issue: Failed to resolve: com.android.support:design:25.3.1

[rafsanahmad007]

the dependency is from official documentation...clean build and make sure you are connected to internet

[Jared Burrows]

@jublikon Since it is not listed in your Android studio, you need to pull the latest. You have not updated in a while.

[Pztar]

I don't understand why they wouldn't include this in new projects.
