Android Studio 无代理

Question

My System has No Proxy Server

So I updated my proxy settings as No Proxy

Also I have commented out proxy settings in my gradle.properties

#systemProp.http.proxyHost=127.0.0.1
#systemProp.http.proxyPort=8080
#systemProp.https.proxyHost=127.0.0.1
#systemProp.https.proxyPort=8080

Still I'm getting

Gradle sync failed: Connection timed out: connect. If you are behind an HTTP proxy, please configure the proxy settings either in IDE or Gradle.

Answer 1

For any future people with issues like that.

TL;DR

0. remove proxy settings from android studio.
1. remove proxy settings from your android project gradle.properties file
2. remove proxy settings from your PC/MAC gradle system files, located at your USER/your OS working directory/gradle/gradle.properties file.

What happened?

Because of insert_reason you turn on proxy(global proxy for all connections) for android studio, gradle took those proxy settings and installed them as default connection so removing proxy from android studio or reinstalling is not enough, gradle.properties will force proxy settings from gradle.properties outside of your android studio.
