[SOLVED] "Failed to attach to the remote VM" connecting jdb to the android emulator on Windows

"Failed to attach to the remote VM" connecting jdb to the android emulator on Windows

I’ve been trying to connect jdb to the android emulator for a little while, and have been met repeatedly with:

jdb -sourcepath ./src -attach localhost:8700

java.io.IOException: shmemBase_attach failed: The system cannot find the file specified
        at com.sun.tools.jdi.SharedMemoryTransportService.attach0(Native Method)

Fatal error:
Unable to attach to target VM.

Not so great. What's the best way of getting round this? I'm running on Windows 7 64bit.

Solution

Currently this is working for me -- making a socket rather than a shared memory connection.

>jdb –sourcepath .\src -connect com.sun.jdi.SocketAttach:hostname=localhost,port=8700

Beforehand you need to do some setup -- for example, see this set of useful details on setting up a non-eclipse debugger. It includes a good tip for setting your initial breakpoint -- create or edit a jdb.ini file in your home directory, with content like:

stop at com.mine.of.package.some.AClassIn:14

and they'll get loaded and deferred until connection.
