Installing the ADT Plugin for Eclipse

Question

I am trying to install the ADT plugin for Eclipse. However, after I have went to \"Install New Software...\" and entered the plugin location https://dl-ssl.google.com/android/ec

Answer 1

Turning off IPv6 worked for me.

Answer 2

I had the same problem. It started working when I unchecked the box labeled "Contact all update sites during install to find required software".

Answer 3

I've faced with the same problem before. In my case this was a problem that I was working under the proxy. I think you also work behind a proxy.

I've solved this problem in the following way. Find the SDKManager.exe and run it. In this program find proxy configuration and fill it there. Then from this program try to update your SDK (maybe this will require you to restart this program).

I do not know why but Eclipse proxy configuration is not working in case of Android ADT.

P.S. You have to use JDK 6 (or 5), not JDK 7!!!

Answer 4

Update

The logged error you provided leads to Install from updatesite hangs under Java 7 and in turn Eclipse Bug 362741 - downloads from update sites hang - (3.7.1 Indigo SR1 windows), see comment 6 specifically (you already applied comment 7).

Please note that while this seems to be a JDK 7 problem at first sight, the linked Java Bug 7077696 - java.net.Socket closes when "PASV" is sent on an authenticated FTP connection classifies the issue as a REGRESSION. Last worked in version 6u26, while you are using 6u30 already. Accordingly, the issue is reported to be fixable by switching to Java 6 elsewhere (implying an earlier version), see e.g. Cannot do any software installs using jdk1.7.0_01 (which uses 6u22):

However, everything works right if I then change the eclipse.ini to change the vm to JDK 1.6:

-vm C:\Java\jdk1.6.0_22\bin\javaw.exe

Oracle's Evaluation concludes, that This does not appear to be a JDK bug, rather it's just the Windows firewall recognizing and blocking the ftp protocol.:

The only difference between JDK7 and older releases is that the JDK is using IPv6 sockets when IPv6 is enabled and so IPv4-mapped IPv6 addresses are used. it may be that Windows or the firewall is not configured to allow IPv6 sockets. [...]

Accordingly, they list a Workaround as well:

Run with -Djava.net.preferIPv4Stack=true

• add a firewall exception for the Java binary.

• run with -Djava.net.preferIPv4Stack=true (which disables IPv6 and uses AF_INET sockets exclusively)

• or disable stateful FTP inspection in the firewall (registry setting or netsh command)

The firewall adjustment seems to be a confirmed workaround as per comment #4 in Socket Exception only in Java 7 (though simply turning it off like there should be handled with care of course).

Good luck!

Presumably you are already aware of Robamaton's answer to Eclipse, Android Plug-in, Install New Software just says “pending” (there are many ADT related questions and strangely it didn't show up immediately in a respective search)? It basically comes down to Codejammer's hint towards Preferences->Network Connections (+1), though with an explanation why it might still fail on your network regardless, see the comments:

Oh, I read that it doesn't respond to general requests from browsers. In any case, network admin confirms it's making a socks connection, but then doing nothing further.

and

Ok, further to previous comment, it's probably trying to connect via. socks 5 - but our network only has socks 4. Admin is going to run the 5 version to see if it then works.

Workaround

Regardless of whether the socks 4 vs. socks 5 proxy settings are actually the problem, a potential workaround might be to install Eclipse and ADT on a different system (ideally on a different network), and copy the resulting folder to yours thereafter (after all, an Eclipse installation is simply a collection of files).

When doing so, please ensure to match 32- vs. 64-bit regarding both the JDK and Eclipse between the source and the target system, because a mismatch would yield other problems (see e.g. my answer to Failed to load the JNI shared library on starting Eclipse).

Answer 5

I had the same problem and it was driving me nuts. I kept trying for a couple of hours--getting the same error message--and at once it worked! So if I were you I'd just leave it for a bit and come back in a couple of hours and try again. There are several other suggested solutions online that I found, but neither of those seemed to make a difference.

Answer 6

If you were unable to get network update working, please try downloading the ADT zip package and installing locally as the download page says.
