테스트는 해보지 않았지만 http://source.android.com/using-eclipse 에 보면 디버깅 하는 방법이 나와있네요.

Debugging the emulator with Eclipse

You can also use eclipse to debug the emulator and step through code. First, start the emulator running:

cd /path/to/android/root
. build/envsetup.sh
lunch 1   # to build the emulator
make      # if you didn't already do this
emulator  # you should see a GUI picture of a phone

In another shell, start DDMS (the Dalvik debug manager):

cd /path/to/android/root
ddms      # you should get a splufty debugging console

Now, in eclipse, you can attach to the emulator:

1. Run > Open Debug Dialog...
2. Right-click "Remote Java Application", select "New".
3. Pick a name, "android-debug" or anything you like.
4. Set the "Project" to your project ("android-java" or whatever).
5. Keep the "Host" set to "localhost", but change "Port" to 8700.
6. Click the "Debug" button and you should be all set.

Note that port 8700 is attached to whatever process is currently selected in the DDMS console, so you need to sure that DDMS has selected the process you want to debug.

You may need to open the Debug perspective (next to the "Java" perspective icon in the upper-right, click the small "Open Perspective" icon and select "Debug"). Once you do, you should see a list of threads; if you select one and break it (by clicking the "pause" icon), it should show the stack trace, source file, and line where execution is at. Breakpoints and whatnot should all work.

감사합니다. ^^

전에 본 글인데,   전에는  이거 보고도  뭔 소리인 인지 몰랐었네요.

내일 해 보고 되는지 확인해서 글 올리겠습니다. ^^

이렇게 쓰여 있는데요.

Debug  퍼스팩티브에   Thread 몇개 나오지만 ,

실제 pause 해 봐야   NativeStart.java 란 곳에서 가서  Suspended 되네요.

이것으로 어떻게  소스 와 연관 지어서 디버깅이 가능 하다는 것인지 모르겠습니다.

모 약식의 방법이 있는데요. 초창기때 써먹던거라..

기본 어플을 수정한후, 그 해당부분만 mmm빌드한후 (소스 논리적 에러없을시 정상) 해당 OUTPUT이미지를 에뮬로 돌려본다..는 방법이 있죠.   뭐 이것도 시간이 꽤드는군요..
