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.
Learn about configuring HTTP proxies 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 am getting this kind of error.
Gradle sync failed: Operation timed out. If you are behind an HTTP proxy, please configure the proxy settings either in IDE or Gradle.
Consult IDE log for more details
what can I try?
It seems like the IDE is not able to connect to internet, could you please make sure it is.
go to File > Settings > Appearance & Behavior > System settings >HTTP Proxy and check if proxy setting is proper, if you don't need proxy to connect to internet then select Auto detect proxy setting then click "check connection" button check if its successful. and clean project and rebuild
hope it works
Recently I started learning the libgdx library and wanted to give it a try on Android Studio.
I followed up some tutorials found on different websites. The problem is when gradle sync starts, it gives an error:
Gradle sync failed: Connection timed out: connect. If you are behind an HTTP proxy, please configure the proxy settings either in IDE or Gradle.
I m not behind any proxy. I tried to disable firewall, enable offline / online gradle sync with the offline folder, forced the sdk to download with http instead of https, changed the distributionUrl into http and changed the distribution url aswell.
Nothing worked.
I don't really know if it is a coincidence or not but when I try to launch the standalone SDK, it gives this error when trying to fetch url saved in the SDK update sites:
Failed to fetch URL https://dl.google.com/android/repository/repository-11.xml, reason: HttpHostConnect Connection to https://dl.google.com refused
Thank you.
Try to do that:
Android SDK Manager > Tools > Options
Check "Force https://...
sources to be fetched using http://..."
