 Here, http://android.git.kernel.org/?p=platform/ 
dalvik.git;a=blob_plain;f=docs/heap-profiling.html;hb=HEAD is a
description about Dalvik Heap Profiling.

In "Android 1.6 ("Donut")" section, it says "Select your application
and click the "dump HPROF file" button. ".
I can find that button in DDMS.

I found there were three items in Device menu:
1.dump device state
2.dump app state(always disabed)
3.dump radio state

Is "dump app state" button the "dump HPROF file" button?

Best Regards.

It's not in a menu.  There's a row of small button icons in the top

  show heap updates
  dump HPROF file
  cause an immediate GC
  show thread updates
  start method profiling
  halt the target VM

 fadden, Thank you!

I tried my ddms and did not see the buttons you mentioned.

In my ddms, there is only 4 buttons:
show heap updates
cause an immediate GC
show threads updates
halt the target VM

I checked out the version of DDMS:v0.8.1.

In fact, I got 1.5 and 1.6 SDK installed in my box. And whatever
version of ddms I ran(start from shell directly), and checked out the
version of DDMS, I got the same :v0.8.1. Is that supposed to be right?

 I have confirmed that these two buttons(dump HPROF file and start
method profiling) only appears since 2.0.
So what the document( http://android.git.kernel.org/?p=platform/  ) says
is wrong.

Yes, you're correct.  Somehow I thought it went into 1.6.  I'll fix
the docs for a future release.
