问题
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?
回答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.
回答2:
In Android Studio 1.4 there are two places, the proxy must be configured: First in Android Studio like Mike described in his answer. And second in the external SDK Manager:
Android Studio | Tools | Android | SDK-Manager | Launch Standalone SDK Manager | Tools | Options
After setting the proxy in the SDK Manager, too, the issue was fixed.
