Seems you can’t connect to that URL.
I can but get a 404, so I am not sure why this is relevant…

Proxy or something like that?

thank you dear Sujan12

yes i am sure there is no proxy which prevent access to net on my system.
i don’t know what is wrong but i have this problem in some plugin such as googleplus and x-socialsharing …
i think there is some thing wrong with android sdk or i don’t know some thing like that
