Android Question

How do I use the latest support library (Getting failed to resolve error with support library 26.0.2 and compileSDKVersion 26)?

I have updated my compileSdkVersion to 26. This is how my gradle file looks now.

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId ##############
minSdkVersion 21
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
testCompile 'junit:junit:4.12'

Predictably, I get warnings for the mismatch(?) in the versions of support library (25.3.1) and the CompileSdkVersion (26).

I have tried to update the support library version to the below versions:

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

  • compile 'com.android.support:appcompat-v7:26.0.2'

The Problem

None of them worked. Both cases show
Failed to resolve
errors. Clicking on
Install Repository and sync project
freezes Android Studio for a couple of seconds and nothing else happens.

Am I missing something?

You should add this in your app Level build.gradle section.


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

Then Clean-Rebuild and Run .
