Cannot build for android using react-native

Question

I'm trying to run react-native run-android but I continuously get this error.I am running on emulator . I started the app using react-native init.

PS: I am running on proxy.

When I am trying to run

react-native run-android

I get:

FAILURE: Build failed with an exception.

*  What went wrong:
 A problem occurred configuring root project 'AwesomeProject'.
 > Could not resolve all dependencies for configuration ':classpath'.
 > Could not resolve com.android.tools.build:gradle:2.2.3.
 Required by:
     :AwesomeProject:unspecified
  > Could not resolve com.android.tools.build:gradle:2.2.3.
     > Could not get resource 'https://jcenter.bintray.com/com/android/tool

 /gradle/2.2.3/gradle-2.2.3.pom'. Received status code 407 from server: 
 Proxy Authentication Required

When I am trying to run

directly in Android Studio

I get:

Error:Could not GET 
'https://jcenter.bintray.com/com/android/tools/build/gradle/2.2.3/gradle-
2.2.3.pom'. Received status code 407 from server: Proxy Authentication 
 Required
<a href="toggle.offline.mode">Enable Gradle 'offline mode' and sync 
project</a>

I have my node_modules installed and I'm not sure what else to try, I've been googling for the last 4 hours and have come up with nothing.

for android studio check this stackoverflow.com/questions/26916951/… — Jose Kj, Commented Oct 17, 2017 at 3:26
The problem is actually quite simple; Your computer can't retrieve the server that has the gradle build tools (no matter you if you use Studio or React Native to compile). Simply using a VPN, or a different internet connection should resolve your issue. — Mdlc, Commented Oct 30, 2017 at 17:09

set your proxy details Inside sdk manager

AndroidStudio->tools->Android->SDKManager->system settings->Http Proxy

your problem is not related to npm and node. you have some gradle problems.check if you can access the URL from browser?

It clearly says <a href="toggle.offline.mode">Enable Gradle 'offline mode' and sync project</a>. Have you tried enabling offline mode? If not, try this:

Go to File -> Settings.

And open the 'Build,Execution,Deployment',Then open the 'Build Tools' -> 'Gradle'.

Then uncheck "Offline work" on the right.

Click the 'OK' button.

Then Rebuild the Project.

For Mac go to AndroidStudio -> Preferences, rest is same.

Try adding these in your gradle.properties:

systemProp.http.proxyHost=proxyURL
systemProp.http.proxyPort=proxyPort
systemProp.http.proxyUser=USER
systemProp.http.proxyPassword=PASSWORD
systemProp.https.proxyHost=proxyUrl 
systemProp.https.proxyPort=proxyPort
systemProp.https.proxyUser=USER
systemProp.https.proxyPassword=PASSWORD
