问题:

I am new to Android Studio. I am using libraries in my project. The maven central has updated version of facebook sdk, while rest of libraries I am using are available on jcenter. I want to know if we can use both these repositories in our project. If yes, then how do I need it to define in gradle file so that studio downloads aar from correct location. Any example would be helpful.

回答1:

and for maven just add to your pom.xml:

<repositories>
    <repository>
      <id>jcenter</id>
      <url>https://jcenter.bintray.com/</url>
    </repository>
</repositories>

回答2:

You never need both. JCenter is a superset of Maven Central, and it should suffice for all the dependencies.

Yes you can use both repositories even though you don't need both unless you want to work offline.

Go to your build.gradle file in your app folder and type the following code:

buildscript 
{
repositories 
{
    jcenter{ url "http://jcenter.bintray.com/" }
    maven { url 'http://repo1.maven.org/maven2' }
}
dependencies 
{
    classpath 'com.android.tools.build:gradle:1.3.0'
}
}

allprojects 
{
repositories 
{
    jcenter()
}
}
