}
dependencies {
    classpath 'com.android.tools.build:gradle:2.0.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}}
repositories{
maven{url 'http://repo1.maven.org/maven2'}
jcenter { url 'http://jcenter.bintray.com/' }}
