Android development : ddms from command line not seeing devices

Question

===============================

*SOLVED * : see answer below

I dont want to use Eclipse.

From the command line:

An emulator is running. adb server is running. "adb devices" lists correctly and I can see my instance on an avd in the output.

However when I manually start DDMS from the command line it just keeps trying to connect. I can find no connection config issues.

Any suggestions (other than "use Eclipse") most welcome!

(yes, it works from within eclipse and ddms shows threads etc)

System : Debian Squeeze

Update : I ran update-java-alternatives to be sure java was set up properly for "Java(TM) SE Runtime Environment (build 1.6.0_20-b02)" . Not too much of a surprise to seasoned Debian users my Java is now worse ... When I run ddms from the command line I get :--

Answer 1

The solution is, in Debian, to force java to use IPv4.

/etc/sysctl.d/bindv6only.conf

net.ipv6.bindv6only = 0

And then from bash

sudo invoke-rc.d procps restart

Also see the Debian bug report for more details.
