问题
I use Android Studio version 1.5.1, and I'm trying to compile 'com.android.volley:volley:1.0.0' in build.gradle, but I can't sync Gradle. I think this error is because of my Internet connection or access being blocked from my country (Iran).

Yes, it's because Google has been blocked in Iran since 2012. You can use a proxy app like Shadowsocks to change your country.
After activating your proxy app, in Android Studio go to file->setting->Appearance & Behavior->System Setting->HTTP Proxy active 'Manual proxy configuration'
and set:
- host name:127.0.0.1 (for example)
- port name:1080 (for example)
and reset Android Studio. When Android Studio resets, activate the HTTPS proxy and sync your Gradle and it will work. ;)
