“Failed to resolve: com.android.support:support-v4:26.0.0” and other similar errors on Gradle sync [duplicate]

Answer 1

Add following dependency in your gradle

Replace

    compile 'com.android.support:support-v4:26.0.0'

with

   compile 'com.android.support:support-v4:25.0.0'

and Replace

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

with

compile 'com.android.support:appcompat-v7:25.0.0'

Answer 2

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.

Answer 3

Either change your build tool version from 26.0.1 to 26.0.0 or you can replace 26.0.0 by 26.+ like below.

compile 'com.android.support:support-v4:26.0.0'

to

compile 'com.android.support:support-v4:26.+"

Do same with all... Hope it helps. Happy Coding! ^_^

Answer 4

This one worked for me

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

google() does the magic with the following configuration

Studio version : 3.0 beta 2

classpath 'com.android.tools.build:gradle:3.0.0-beta2'

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

Answer 5

Replace this:

    compile 'com.android.support:recyclerview-v7:26.0.0'

With this

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

Do same with all

Update - new version released

    compile 'com.android.support:recyclerview-v7:26.1.0'

Answer 6

I don't have an Android wear project, but I had the same problem when I wanted to upgrade the Support Library version for an existing project to 26.0.0. Since 26.0.0 the support libraries are available through Google's Maven repository. So I had to add the repository to my build. gradle file.

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