React-native: [Android] Connection refused from Gradle when behind a proxy

[nadeemshaik]

Well, I am getting this error when I am trying to run "react-native run-android". Seems to be a simple error but I can't figure it out a solution.

Can this be because of a proxy server (University restrictions) : Does react-native-cli accept proxy params ?

Just in case:

Starting JS server...
Building and installing the app on the device (cd android && ./gradlew installDebug)...

Could not install the app on the device, see the error above.

Might be related to the proxy indeed.

Can you fetch it using your browser as well as wget?

[mkonicek]

The CLI doesn't accept proxy params.

[nadeemshaik]

Hey @mkonicek , I tried that, but gives the exact same error. After googling a bit more about gradle settings, just found out the solution though.I just set the following in gradle.properties in the android folder

systemProp.http.proxyHost=proxyHost
systemProp.http.proxyPort=proxyPort

systemProp.https.proxyHost=proxyHost
systemProp.https.proxyPort=proxyPort

Works now :)

[kmagiera]

great to hear you've found the solution

[dharmesh-khandelwal]

@nadeemshaik Thanks, I had the same issue. Fixed by setting proxy in gradle properties.

[s0nskar]

If your proxy uses authentication add these line too

systemProp.http.proxyUser=YOUR_USERNAME
systemProp.http.proxyPassword=YOUR_PASSWORD

[tassoman]

must be set in android/gradle.proprieties not in settings.gradle

[adrianovieira]

Can I do these proxy settings as a global settings or only by project as <AwesomeProject>/android/gradle.proprieties?

[husainkhan]

Still not Working.
I did set the proxy and the port but still it gives the same error.

[botdotcom]

Not working for me either!

[sujitpk-perennial]

No luck for me. I am facing this problem for all projects now.

You can set the proxy to automatic and rerun the android studio and it worked for me.

Thank you!!
