how to use a proxy connection with android studio

Question

I'm trying to run a "hello world" application in android studio. My connection is via proxy. When I try run the "hello world app", android studio show me the next error:

Error running Prueba: Gradle project sync failed. Please fix your project and try again.

If I configure in: "File/setting -> HTTP Proxy" and next put my proxy configuration, the error is the next:

Error:Could not GET 'http://jcenter.bintray.com/com/android/tools/build/gradle/0.12.2/gradle-0.12.2.pom'. Received status code 407 from server: Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ) <a href="toggle.offline.mode">Enable Gradle 'offline mode' and sync project</a>

How can I fix that error?

Answer 1

There error indicates that proxy authentication is needed. To authenticate to your proxy server go back to File->Setting->HTTP Proxy, check the box for Proxy authentication and enter your credentials there. Also, click the check connection button to test that your connection is successful.
