Connect a Java debugger to a running activity

[teras]

Hello people!

I am trying to manually connect my IDE (Netbeans) to a running Android
Activity.
I know that there is already a Netbeans plugin that is able to do
this, but it has some bugs and I want to go my way, and see how things
should be done.


In order to launch the application in debug mode, I do something like
this:
adb shell "am start -D -n com.project.package/.ProjectActivity"
which starts the application in debug mode and waits for connections.

Now, in Netbeans I tried to connect to the 8700 port, as described in
the docs, but with no luck. By using DDMS I also found that the actual
port for this application is 8611, so I tried to connect there, no
luck again.
The error code in both cases was "handshake failed - connection
prematurally closed"

I also tried to port forward, as was mentioned in the documentation,
with a command like
adb forward tcp:8000 tcp:8700
or
adb forward tcp:8001 jdwp:558

Only the last option did something: it didn't fail with error but
again the IDE was frozen and no activity was performed.

Can anybody help me?

The TCP ports only exist on your workstation. The VM is connected to
ADB through a "jdwp" port.

If you do a "remote debug" session to "localhost:8700" it will connect
to whichever VM you have highlighted in DDMS.
