Install repository and sync project ошибка

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?

If you are facing Google maven respository error like this,

ERROR: Failed to resolve: com.android.support:appcompat-v7:23.3.0
Add Google Maven repository and sync project
Show in Project Structure dialog
Affected Modules: app


ERROR: Failed to resolve: com.android.support:support-v4:23.3.0
Add Google Maven repository and sync project
Show in Project Structure dialog
Affected Modules: app


ERROR: Failed to resolve: com.android.support:design:23.3.0
Add Google Maven repository and sync project
Show in Project Structure dialog
Affected Modules: app

Try the following method,

In your project’s build.gradle file, add following lines into the repositories blocks like this:

repositories {
        maven {
            url 'https://maven.google.com'
        }
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }

There is 2 respositories, So make changes to both of them.

Now Try to Sync

Hit Thanks If it helped you, Which will help others to notice easily

With latest Android Studio, I change the targetSdkVersion and compileSdkVersion of my old exercise to 28. And I also have to use updated com.android.support:appcompat-v7 and com.android.support.constraint:constraint-layout. After fail in rebuild, it’s a number of WARNING and ERROR.

As suggested, I change  ‘compile’, ‘testCompile’ and ‘androidTestCompile’ to ‘implementation’, ‘testImplementation’ and ‘androidTestImplementation’, in app/build.gradle.

To fix the error of Failed to resolve: com.android.support:appcompat-v7:28.0.0 and com.android.support.constraint:constraint-layout:1.1.3, I add the follow lines of Google Maven repository to build.gradle.

        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }

And rebuild the project. At least it works for me now.

So, how to know the latest version of com.android.support:appcompat-v7 and com.android.support.constraint:constraint-layout?

For Support Library, you can check here: Android Developers > Platform > Libraries > Recent Support Library Revisions

28.0.0 is the recentest stable release of Support Library released on September 21, 2018 and will be the last feature release under the android.support packaging.

For ConstraintLayout, Google announced at https://androidstudio.googleblog.com/2018/08/constraintlayout-113.html.

You can also check from Maven repository:
>> com.android.support >> appcompat-v7
>> com.android.support.constraint >> constraint-layout

Recently, Google start to distribute android support library by maven repo.

You can try add

maven { url 'https://maven.google.com' }

in your project level build.gradle

example:

buildscript {
    ext.kotlin_version = '1.1.3-2'
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha9'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
        mavenCentral()
        maven { url 'http://devrepo.kakao.com:8088/nexus/content/groups/public/' 
}
    }
}

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

Friend the most solution for the «install repository and sync project» is Go to File>Invalidate Cache/Restart you will be shown a window asking to confirm restart.Be aware that local history will be cleared.
if that does not check the library version that u installed and change it what u have.

Here your dependency was not matching with your BuildTools so you need to give dependency as per your you build tool version for the resolution you need to remove all dependency or add from Project structure or else change version name as per build version like following,

Like I have already install build tool 25.0.1 and I give dependency like compile 'com.android.support:recyclerview-v7:25.0.2' So I need to change like compile 'com.android.support:recyclerview-v7:25.0.1' So It will work.
