Library search dependency on android studio 3.0

Question

After upgrading to Android Strudio 3.0, I tried adding a library from

project structure -> dependencies -> add library

but the search does not work, nothing was found. My build.gradlefile looks like this:

buildscript {
repositories {
    jcenter()
    google()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0'

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

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

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

and 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

Answer 1

It seems that only the com.android.xx and com.google.xx libraries can be searched in the library.
