"Failed to resolve: com.android.support:support-v4:26.0.0" and other similar errors on Gradle sync

I have just created a new Android Studio project for both Android Mobile and wear. The initial gradle build failed because I am getting several errors-

Error: Failed to resolve: com.android.support:support-v4:26.0.0

Error: Failed to resolve: com.android.support:percent:26.0.0

Error: Failed to resolve: com.android.support:recyclerview-v7:26.0.0

Error: Failed to resolve: com.android.support:support-annotations:26.0.0

With each error, I am given the option to Install repository and sync project, but nothing happens when I click on it. I have spent several hours trying to find why I am getting these errors, but I can't find any solutions. Does anybody know how to fix these very frustrating errors? Thank you!

build.gradle (project)

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

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

    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

        // NOTE: Do not place your application dependencies here; they   belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

build.gradle (mobile)

    })
    wearApp project(':wear')

    compile 'com.android.support:appcompat-v7:26+'

    compile "com.android.support:support-core-utils:26+"
    testCompile 'junit:junit:4.12'
}

build.gradle (wear)

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.georgeberdovskiy.androidweartest"
        minSdkVersion 23
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    provided 'com.google.android.wearable:wearable:2.0.4'
    compile 'com.google.android.support:wearable:2.0.4'
    compile 'com.google.android.gms:play-services-wearable:11.0.4'
    compile "com.android.support:support-core-utils:26+"
}

I am sure that my version of Android Studio is updated, and all support repositories and APIs are installed. enter image description here

Solution

  • The reason that my project was giving me these errors was because I created the project for Android Platform 26. However, Wear currently doesn't support 26, and it is essential to change the target and compile SDK versions to 25 in the wear module of build.gradle.

    Link to Android Developers documentation - https://developer.android.com/training/wearables/apps/creating.html#setting-up-a-phone

    build.gradle (wear)

    apply plugin: 'com.android.application'


android {
compileSdkVersion 25
buildToolsVersion "26.0.1"

defaultConfig {
    applicationId "com.georgeberdovskiy.findmyphone"
    minSdkVersion 25
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'),       'proguard-rules.pro'
    }
    }
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.google.android.support:wearable:2.0.3'
provided 'com.google.android.wearable:wearable:2.0.3'
compile 'com.google.android.gms:play-services-maps:11.0.4'
compile 'com.google.firebase:firebase-core:11.0.4'
compile 'com.google.firebase:firebase-database:11.0.4'
compile 'com.google.android.gms:play-services-wearable:11.0.4'

}

apply plugin: 'com.google.gms.google-services'

    I only needed to change the compile and target SDK versions to 25 in the wear module. I left them as 26 for the mobile module.
