问题:

I have a project whose compileSdkVersion and targetSdkVersion is 25. When I tried to upgrade the version to 26, I got the following error:

Could not find com.android.support:support-annotations:26.1.0. Required by:     project :app     project :app > com.android.support:support-compat:26.1.0  Please install the Android Support Repository from the Android SDK Manager. Open Android SDK Manager

I opened Android SDK Manager, but could not find Android Support Repository to install.

How can I fix this problem?

Here's my app and project gradle files:

apply plugin: 'com.android.application' apply plugin: 'com.neenbedankt.android-apt' apply plugin: 'io.fabric'  android {     compileSdkVersion 26     buildToolsVersion '26.0.3'      defaultConfig {         //my default config     }      signingConfigs {         config {             //config         }     }      buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'             signingConfig signingConfigs.config         }         debug {             versionNameSuffix ".debug"         }     }      lintOptions {         /*disable 'InvalidPackage'*/         abortOnError false     }      repositories {         jcenter()         mavenCentral()         maven { url 'https://maven.fabric.io/public' }         maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }         maven { url "http://dl.bintray.com/populov/maven" }         maven { url 'https://oss.sonatype.org/content/repositories/ksoap2-android-releases' }     }      compileOptions {         sourceCompatibility JavaVersion.VERSION_1_7         targetCompatibility JavaVersion.VERSION_1_7     } }  def support = '26.1.0' def rounded_image_view = "2.3.0"  dependencies {     compile fileTree(include: ['*.jar'], dir: 'libs')     compile "com.android.support:support-annotations:$support"     compile "com.android.support:appcompat-v7:$support"     compile "com.android.support:support-v4:$support"     compile "com.android.support:design:$support"     compile "com.android.support:cardview-v7:$support"     compile "com.android.support:recyclerview-v7:$support"     compile "com.android.support:support-vector-drawable:$support"     compile "com.android.support:support-compat:$support"     compile "com.android.support:support-core-ui:$support"     compile 'com.jakewharton:butterknife:7.0.1'     compile 'com.wrapp.floatlabelededittext:library:0.0.6'     /*compile 'javax.inject:javax.inject:1'*/      //needed to resolve compilation errors, thanks to tutplus.org for finding the dependency     compile 'com.michaelpardo:activeandroid:3.1.0-SNAPSHOT'     compile 'com.balysv.materialmenu:material-menu:1.5.2'     compile 'com.flyco.dialog:FlycoDialog_Lib:1.1.6@aar'     compile 'com.flyco.animation:FlycoAnimation_Lib:1.0.0@aar'     compile 'com.nhaarman.listviewanimations:lib-core:3.1.0@aar'     compile 'com.nhaarman.listviewanimations:lib-manipulation:3.1.0@aar'     compile 'com.nhaarman.listviewanimations:lib-core-slh:3.1.0@aar'     compile 'com.norbsoft.typefacehelper:library:0.9.0'     compile 'com.quinny898.library.persistentsearch:library:1.1.0-SNAPSHOT'     compile 'com.rengwuxian.materialedittext:library:2.1.4'     compile 'com.squareup.picasso:picasso:2.5.2'     compile 'com.squareup.okhttp:okhttp:2.4.0'     compile 'jp.wasabeef:picasso-transformations:2.1.0'     compile 'com.tuenti.smsradar:library:1.0.4'     compile 'com.viewpagerindicator:library:2.4.1@aar'     compile 'com.xgc1986.android:parallaxpagertransformer:1.0.3'     compile 'com.github.medyo:fancybuttons:1.5@aar'     compile 'com.google.code.ksoap2-android:ksoap2-android:2.6.5'     compile 'com.google.dagger:dagger:2.0.1'     compile('com.github.afollestad.material-dialogs:core:0.8.5.3@aar') { transitive = true }     compile 'com.google.android.gms:play-services-gcm:11.0.4'     compile 'me.relex:circleindicator:1.2.2@aar'     compile 'com.github.rubensousa:gravitysnaphelper:1.1'     compile 'com.miguelcatalan:materialsearchview:1.4.0'     compile 'com.makeramen:roundedimageview:2.3.0'     compile 'com.journeyapps:zxing-android-embedded:3.5.0'     compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') {         transitive = true;     }     compile 'com.github.bumptech.glide:glide:3.7.0'     compile 'org.jsoup:jsoup:1.8.3'     apt "com.google.dagger:dagger-compiler:2.0.1"     provided 'org.glassfish:javax.annotation:10.0-b28'     androidTestCompile(             'org.mockito:mockito-core:1.9.5',             'org.hamcrest:hamcrest-core:1.1',             'org.hamcrest:hamcrest-integration:1.1',             'org.hamcrest:hamcrest-library:1.1'     )      compile 'com.romandanylyk:pageindicatorview:0.2.0@aar'     compile 'ca.barrenechea.header-decor:header-decor:0.2.8'     compile "com.makeramen:roundedimageview:$rounded_image_view"     compile 'cz.msebera.android:httpclient:4.4.1.2'     compile 'de.hdodenhof:circleimageview:2.2.0'   }  apply plugin: 'com.google.gms.google-services'

And:

buildscript {     repositories {         jcenter()         mavenCentral()         maven { url 'https://maven.fabric.io/public' }         maven { url "https://oss.sonatype.org/content/repositories/snapshots" }     }      dependencies {         classpath 'com.android.tools.build:gradle:2.3.3'         classpath 'com.google.gms:google-services:3.0.0'         classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'         classpath 'io.fabric.tools:gradle:1.22.1'     } }  allprojects {     repositories {         maven { url "http://dl.bintray.com/populov/maven" }         maven { url "https://jitpack.io" }         mavenCentral()         jcenter()     }      gradle.projectsEvaluated {         tasks.withType(JavaCompile) {             options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation"         }     } }

回答1:

I answer my own question:

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

allprojects {     repositories {         ...         maven { url 'https://maven.google.com' }//this line is added         mavenCentral()         jcenter()     } }

worked for me because my gradle version was 3.x. I think the answer of @shizhen is also correct but the gradle version should be changed to 4.x+.

For more information refer to difference between google() and maven { url 'https://maven.google.com' }

回答2:

Try to add "google()" repo inside your buildscripts block.

buildscript {     repositories {         google() // add this new line.          jcenter()         mavenCentral()         maven { url 'https://maven.fabric.io/public' }         maven { url "https://oss.sonatype.org/content/repositories/snapshots" }     }      dependencies {         //classpath 'com.android.tools.build:gradle:2.3.3'         classpath 'com.android.tools.build:gradle:3.0.1' // change the gradle plugin version to 3.0.1.         classpath 'com.google.gms:google-services:3.0.0'         classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'         classpath 'io.fabric.tools:gradle:1.22.1'     } }

Also, maybe change your gradle wrapper version to 4.1 inside 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

If still have issue, try to install the later Android Studio 3.1.2.

回答3:

Here is Android Support Repository in SDK Manager

回答4:

The google() should be put as the first repo and upgrade you Android Gradle Plugin version to 3.0.1

classpath 'com.android.tools.build:gradle:3.0.1'
