Maven Dependencies with Android Studio / Gradle

The “repositories” block in the buildscript section only applies to the build environment. You also need to specify which repository to use when resolving dependencies for building your project, so you need to put something like the following in your build.gradle file:

repositories {
    mavenCentral()
}

Your complete file would look something like this:

buildscript {
    repositories {
        maven { url 'http://repo1.maven.org/maven2' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.4'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.google.android:support-v4:r7'
}

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 16
    }
}

Note the two instances of “repositories”. You can read more about what this actually means in the gradle docs.
