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.

Answer 2

Adding this line somewhere in eclipse.ini helped me:

 -Djava.net.preferIPv4Stack=true

The directive name speaks for itself.

Answer 3

I've had this problem too. I've always found that if you close eclipse first before connecting the device, running an emulator, or starting ddms, everything works just fine.

I think the Eclipse SDK hogs the connection and prevents ddms from accessing the device or emulator.

Answer 4

The IPv4 did not work for me, but plugging the device on a different USB port solved this issue (via Android device not showing up in DDMS)
