I have Android Studio v3.2.
Every time I try to build with internet connected, the build process goes on forever.
When I try offline it gives me this error:
Could not download builder.jar (com.android.tools.build:builder:3.2.0): No cached version available for offline mode
So I tries disabling offline mode in Settings > Gradle. Then I get this error:
Unknown host 'dl.google.com'. You may need to adjust the proxy settings in Gradle.
Enable Gradle 'offline mode' and sync project
Learn about configuring HTTP proxies in Gradle
So I downloaded Gradle and set Service directory path of Settings>Gradle to manually downloaded directory. Then I get this error:
Unknown host 'services.gradle.org'. You may need to adjust the proxy settings in Gradle.

Is there any way I can work offline or I can fix the online problem.
You might need to have internet connectivity to download the maven library dependencies and gradle.
go to FIle==>Setting==>Appearance==>System Settings==>HTTP Proxy
Set Auto Proxy click Apply and check the connection.
then File==>Sync with gradle files.
If it displays an edit proxy dialog ignore it and set "do not display thi dialog again"
In my android studio 3.0 i am continuously getting this error -
Cannot start internal HTTP server. Git integration, JavaScript debugger and LiveEdit may operate with errors. Please check your firewall settings and restart Android Studio.
after this my gradle sync also failed stating the error -
Gradle sync failed: Could not connect to server [a3ea2c7d-cc16-4af2-82a9-037277903c02 port:49555, addresses:[/127.0.0.1]]. Tried addresses: [/127.0.0.1].
One thing to note down that this gradle sync failed when it(gradle) is connecting to gradle daemon.
i have tried all the options from stack overflow like netsh winsock reset etc.
But nothing work for me.
Also to mention i do not use embedded JDK in AS. I have provided it my downloaded jdk8.
How to solve this problem.
Thanks in advance.
Make sure your machine is connected to the internet.
Check the link here: Configure Android Studio - Proxy
I personally recommend that you try disabling the proxy if it is enabled.
Go to Windows Firewall -> Inbound & Outbound Rules -> add java.exe from JDK path & studio.exe from Android Studio directory.
I just installed Android studio 2.3.1, but after starting it is telling me "Grade sync failed: connection time out: connect consult IDE log for more details". Pls I don't know what to do.
Caused by: java.util.zip.ZipException: error in opening zip file
This mean that a file that Gradle has downloaded has become corrupted due to somehow or some reason. This might be the download of Gradle itself (which the wrapper does) or any dependency that Gradle has downloaded to run your build.
Gradle doesn't attempt to detect or resolve the problem, so you need to fix it manually. The solution is often to purge Gradle's download caches and let it get fresh copies of what it needs.
To do that, delete the .gradle directories in both your home directory and in your project's root directory and try building again.
In window home directory of gradle is
C:\Users\User.gradle
In Mac OSX home directory
/Users/User_name/.gradle
If you still haven't figured out this problem yet, it's because you literally have no internet connection which is mandatory for gradle building since the platform checks for potential updates for say, sdk versions, from a server.
However, if you want to build and do your work offline, then go to File -> Settings -> Build, Execution, Deployment -> Gradle -> Check Offline work under Global Gradle settings
With reference to #DaveNOTDavid's answer, i tried this: Go to File->Settings->Build,Execution,Deployment->Gradle-> and select "Use default gradle wrapper(recommended)". Then sync your project, everything will work fine. But you need an internet connection.
I was facing the same issue while downloading the gradle zip from https://services.gradle.org/distributions/gradle-4.1-all.zip. My issue related to proxy settings, I disabled the proxy & click on Try Again button in build.gradle file.
In my case i activated antivirus it blocks the downloading gradle files turn of your firewall settings
Click on the SDK Manager and click SDK Tools and check if NDK and CMAKE are checked or not. If they are not checked download and install them. And if the problem persists just try it with a stable internet connection with a fast or a moderate speed. It had happened with me also when I was doing it with mobile phone internet then I tried it with a broadband with fast internet.
Basically it's a network issue. if you are working using wifi use vpn that would solve the problem
connection timed out:
solution: Just disable your anti-virus for an hour and restart the android studios, in my case my antivirus blocked the connection. while restarting the android studios firewall will ask you the permission, allow it and its all done. The gradle will build successfully
These situations generally occur due to the problem in downloading Gradle components, to overcome this, check your internet proxy and connection properly.
Just try to use some other source internet connection instead of the one you were using while having this error. Like I faced the same problem and I disconnected my system from the wifi and connected it to my personal mobile hotspot. then go to file->Invalidate Caches/ Restart...
and your Gradle will build successfully this time.
I often get the following error while trying to sync gradle
Error:Connection timed out: connect. If you are behind an HTTP proxy, please configure the proxy settings either in ide or gradle.
Sometimes that i don't get the error, gradle sync takes more than 1 hour
Try to open and check this url in your browser
Google DL and try downloading latest Gradle version from Gradle Site
If you aren't able to access and download the files the time consumption is because you might be getting 403. You might not be having download access on your machine.
Contact your network administrator and ask for access.
Configure your gradle.properties with below settings -
systemProp.http.proxyPassword=
systemProp.http.proxyHost=
systemProp.http.proxyPort=
systemProp.http.proxyUser=
systemProp.https.proxyPort=
systemProp.https.proxyUser=
systemProp.https.proxyHost=
systemProp.https.proxyPassword=
Or you can go to Settings -> HTTP Proxy -> Provide details.
Now go to SDK Manager -> Tools -> Options -> Set provided proxy server and port.
Rebuild your project, you would be prompted with proxy dialog -> Check https proxy and build.
EDIT 1
If above solution does not work. Go to settings -> Search Gradle -> Check offline mode under Global gradle settings.
I Just encounter the same issue in my office network.
By default the "HTTP Proxy" is set to "No Proxy" in Android Studio.
I fix this the problem by making "HTTP Proxy" to "Auto Detect".
If it was working fine earlier and stopped all of a sudden, try removing any recent dependency that you have added and sync again. If you can't recall then try running it in offline mode.
I am trying to run the react native examples for androind on windows. My system is setup behind a corporate proxy. i am unable to get gradle to work though.
Following proxy settings are defined in the global gradle.properties.
systemProp.http.proxyHost=<proxy.url>
systemProp.http.proxyPort=8080
systemProp.https.proxyHost=<proxy.url>
systemProp.https.proxyPort=8080
I tried running the build from android studio(2.0), same story. My network proxy is properly configured there, i checked, i can access the internet from it.
i changed my build tools to point to the gradle distribution that comes with it, that didn't change anything either.
i keep getting an error saying
"Unknown host <my.proxy.url>. You may need to adjust the proxy settings in gradle"
I also checked, i can download the poms it requires from my browser. it seems as if gradle is unable to work from behind a proxy, at all.
can anyone help?
