Android Native Heap Inspection DDMS

Question

I'm having trouble getting the native heap information from my HTC Magic running Android 2.2.1. I've configured the standalone DDMS setting "native=true" and used the commands:

• adb shell setprop libc.debug.malloc 1
• adb shell stop
• adb shell start

However, when I try to check if the property is set correctly by issueing the command:

• adb shell ls

I get the following log message:

• "/system/bin/sh: Missing module /system/lib/libc_malloc_debug_leak.so required for malloc debug level 1"

Can someone help me with getting the native heap allocations?

Thanks,

I'm using this on a Xoom : http://code.google.com/p/honeycomb-sdk-united-base/source/browse/trunk/system/lib/?r=8

Download the raw file using "save as"and then

adb remount
adb push libc_malloc_debug_leak.so /system/lib/libc_malloc_debug_leak.so

You already have root so the adb remount and pushing to /system/lib should work for you.

You can "probably" also build that library by building Android from source. But this was quicker for me.
