debugging an app startup with android maven plugin

问题

I'm working with the latest version of android maven plugin. I use android:deploy and android:run to launch my app on my device. When I want to debug, I go into DDMS in eclipse and check the green bug icon for my app. Everything works fine... but I can only debug a running app, ie it has already started. If I put a breakpoint in my application constructor or onCreate, it wont stop (obviously because the application has started and the debugging didn't been activated... yet).

So my question is: how can I start my app in debug mode directly from maven like I would do for an app that I start from eclipse ?

thanks ahead

Thanks to Lukasz, I found the command in Idea that is launched to trigger the debug mode. Basically, the application is deployed with android:deploy but instead of android:run, I launch a shell "am" command with -D. Here's the usage for anyone interested.

ovh-ybi$ adb shell
# am
usage: am [subcommand] [options]

start an Activity: am start [-D] <INTENT>
    -D: enable debugging

send a broadcast Intent: am broadcast <INTENT>

start an Instrumentation: am instrument [flags] <COMPONENT>
    -r: print raw results (otherwise decode REPORT_KEY_STREAMRESULT)
    -e <NAME> <VALUE>: set argument <NAME> to <VALUE>
    -p <FILE>: write profiling data to <FILE>
    -w: wait for instrumentation to finish before returning

start profiling: am profile <PROCESS> start <FILE>
stop profiling: am profile <PROCESS> stop

<INTENT> specifications include these flags:
    [-a <ACTION>] [-d <DATA_URI>] [-t <MIME_TYPE>]
    [-c <CATEGORY> [-c <CATEGORY>] ...]
    [-e|--es <EXTRA_KEY> <EXTRA_STRING_VALUE> ...]
    [--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE> ...]
    [-e|--ei <EXTRA_KEY> <EXTRA_INT_VALUE> ...]
    [-n <COMPONENT>] [-f <FLAGS>] [<URI>]

Instead of android:deploy and android:run you could just launch your application in debug by eclipse and not by maven. You have to have your project configured properly to do this.

You can deploy and start it using this post. To debug I guess and hope you only need to change some parameters.
