Answer 1

The problem was firewall blocking studio to update new library.When I disable firewall it works fine.

As far as I know, connection timing out is a network problem .Go to File > Settings > Appearance and Behaviour > System Settings > HTTP Proxy and make sure your proxy settings look like this:

Perform gradle sync and see how it goes.

Oaf

i tried it with no proxy but it still show same error.I doubt the error start after the studio update.I did the update yesterday.I am not sure but i noted this error after that. – Psycho

I see, unfortunately I can't tell what's wrong.I'll try to help you find a solution later today. – Oaf

I tried creating new project with appengine .That project also show this error while build. – Psycho

Are you connected to the Internet, and how strong is your connection? – Oaf

yes i am connected to internet the connection is ok about 1mb/sec.But I think it has some problem connecting with studio I think.Because when I try to update my android support library it shows connection refused and nothing is installed.Is it may be some problem in my settings? – Psycho

Okay.Then, yes it is a problem with a setting in Android Studio.Since you have a fast connection, I suggest you uninstall the Android Studio you have, and download the latest version from the official site. When it asks you if you want to import old settings, select the third option and then try everything all over again. – Oaf

Let us continue this discussion in chat. – Psycho

Answer 3

I had the same issue and I fixed it by specifying the proxy settings in gradle.properties file. Next to backend build.gradle file, I've created gradle.properties file and put there this:

systemProp.http.proxyHost=<prox_host>
systemProp.http.proxyPort=<proxy_port>

Specifying the proxy properties in Studio did not help me.
