Add dependency on android studio

Question

I wondered where exactly I put a dependency like this in android studio:

<dependency>
  <groupId>com.code-troopers.betterpickers</groupId>
  <artifactId>library</artifactId>
  <version>2.2.1</version>
  <type>aar</type>
</dependency>

Android Studio uses the Gradle as Database and dependency manager, but still uses the Maven central repository to resolve these dependencies.

When I need something like:
1 - i search for the dependency on google with the prefix "Maven"
2 - on the site of the Maven repository, I click on the Gradle tab that already gives the line that I should add in the Gradle build script.

To add the dependency on Android Studio, open the project’s build.Radle file, and add the dependency on the group dependency as in the example of a complete script:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}
apply plugin: 'android'

dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')
    compile 'log4j:log4j:1.2.11'
    compile 'de.mindpipe.android:android-logging-log4j:1.0.2'
    compile 'org.roboguice:roboguice:3.+'
    provided 'org.roboguice:roboblender:3.+'

    compile 'com.code-troopers.betterpickers:library:2.0.3'

}

allprojects {
    repositories {
        mavenCentral()
    }
}

android {
    compileSdkVersion 8
    buildToolsVersion "19.1"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

The link to the text of Gradle is a personal suggestion, because I found quite interesting and direct approach.

This format you indicated is the format used by Maven to declare a dependency.

The Android Studio uses Gradle to manage dependencies and build applications.

There are two ways to declare a dependency on Gradle:

Using the identifiers group, name and version

dependencies {
    compile group: 'com.code-troopers.betterpickers', name: 'library', version: '2.2.1'
}

Using the short form group:name:version

dependencies {
    compile 'com.code-troopers.betterpickers:library:2.2.1'
}

Android Studio uses the repository jCenter to resolve dependencies, this is stated in build.Gradle automatically when a new project is created.

repositories {
    jcenter()
}
