Could not resolve com.android.support:appcompat-v7:26.1.0 in Android Studio new project
Solution 1
Finally I fixed the problem by modifying build.gradle
like this:
android {
compileSdkVersion 26
buildToolsVersion "26.0.2"
defaultConfig {
minSdkVersion 16
targetSdkVersion 26
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:design:26.1.0'
}
I've removed these lines as these will produce more errors:
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
Also I had same problem with migrating an existing project from 2.3 to 3.0.1 and with modifying the project gradle files like this, I came up with a working solution:
build.gradle (module app)
android {
compileSdkVersion 27
buildToolsVersion "27.0.1"
defaultConfig {
applicationId "com.mobaleghan.tablighcalendar"
minSdkVersion 16
targetSdkVersion 27
}
dependencies {
implementation 'com.android.support:appcompat-v7:25.1.0'
implementation 'com.android.support:design:25.1.0'
implementation 'com.android.support:preference-v7:25.1.0'
implementation 'com.android.support:recyclerview-v7:25.1.0'
implementation 'com.android.support:support-annotations:25.1.0'
implementation 'com.android.support:support-v4:25.1.0'
implementation 'com.android.support:cardview-v7:25.1.0'
implementation 'com.google.android.apps.dashclock:dashclock-api:2.0.0'
}
Top level build.gradle
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
}
}
allprojects {
repositories {
google()
jcenter()
}
}

goto Android->sdk->build-tools directory make sure you have all the versions required . if not , download them . after that
goto File-->Settigs-->Build,Execution,Depoyment-->Gradle
choose use default gradle wapper (recommended)
and untick Offline work
gradle build finishes successfully for once you can change the settings
If it dosent simply solve the problem
check this link to find an appropriate support library revision
https://developer.android.com/topic/libraries/support-library/revisions
Make sure that the compile sdk and target version same as the support library version. It is recommended maintain network connection atleast for the first time build (Remember to rebuild your project after doing this)
Solution 3
try this :
android {
compileSdkVersion 26
buildToolsVersion "26.0.1"
defaultConfig {
targetSdkVersion 26
}
}
compile 'com.android.support:appcompat-v7:25.1.0'
It has worked for me
Solution 4
I tried all of the above and nothing worked for me.
Then I followed Gradle Settings > Build Execution, Deployment > Gradle > Android Studio and checked "Disable embedded Maven repository".
Did a build with this checked and the problem was solved.
Solution 5
Just go to File\Settings\Gradle. Deselect the "Offline work" box. Now you can connect and download any necessary or missing dependencies

I know about this questions:
Failed to resolve: com.android.support:cardview-v7:26.0.0 android
Could not resolve com.android.support:appcompat-v7:26.1.0 [duplicate]
And I've read this documentations:
Migrate to Android Plugin for Gradle 3.0.0
So I'm posting this question believing its not a duplicate.
I've installed Android Studio 3.0.1. I didn't have any previous version before and I started a new project.
Every setting in Gradle file have been set by Android Studio itself and I've checked them all.
These are the file contents:
build.gradle (Module:app)
apply plugin: 'com.android.application' android { compileSdkVersion 26 defaultConfig { applicationId "com.example.administrator.as301test" minSdkVersion 16 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 { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.0.2' implementation 'com.android.support:design:26.1.0' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' }
Top level build.gradle
buildscript { repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { google() jcenter() } } task clean(type: Delete) { delete rootProject.buildDir }
gradle-wrapper.properties
distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip
I use
google()
in repositories as here clearly says:// If you're using a version of Gradle lower than 4.1, you must instead use: // maven { // url 'https://maven.google.com' // }
My gradle version is 4.1 so I don't need above code.
But I still get this error as the others have been asking about:
Error:Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.support:appcompat-v7:26.1.0.
Why should I get this error when I'm creating a new project in
AS 3.0.1
and it has been set all the necessary settings?Update
@Rohit's answer somehow solved the issue but I still get same error for some other dependencies.
