Advanced Android crash analysis?

Is there a way to get more useful information from an android crash? Deliberately inducing a UAF crash in android ICS I get the following output to my logcat, but is there a way to do a more complete stack dump and heap dump at the time of the crash? I can't seem to do it in ddms because as soon as the fatal signal is hit ddms abandons the process (because it doesn't exist anymore)

android porting: "service 'SurfaceFlinger' died"

I am trying to boot blaze board with jellybean 4AJ.2.5P2. When I am trying to boot, I got the following error.
init: Failed to open socket 'property_service': Address family not supported by protocol
I have used the below bootargs:
setenv bootargs 'console=ttyO2,115200n8 mem=1G androidboot.console=ttyO2 root=/dev/mmcblk0p2 rw rootdelay=2 rootfstype=ext3 init=/init vram=32M omapfb.vram=0:16M androidboot.console=ttyO2 consoleblank=0'
setenv bootcmd 'mmcinit 0;fatload mmc 0 0x80000000 uImage; bootm 0x80000000'
boot
These are the log which i got.

I have searched a lot, i couldn't find anything useful.
Any help will be appreciated!
Thank you!
UPDATE:
We had changed lot in kernel. Now the above mentioned errors are no more. But, I am facing the problem in surface flinger.
When Surface flinger is started, crash is occurred and at last, logcat shows that "service 'SurfaceFlinger' died"

Please help me to debug it.
Any Guidance will be appreciated!!

I had the same issue with my Nexus 7 AOSP build.
Its was an LOL moment for me after spending 2 days behind this issue.
I hope this will help you in your journey of building ROM using AOSP for android devices.
You are missing some proprietary binaries required to run hardware components used by devices. Those lib are not built by using AOSP make command.
Those binaries can be found here: https://developers.google.com/android/nexus/drivers#flo. Make sure your binaries are for the correct Android version you're building (5.1.1 in my case).
Extract the downloaded files into the root of your working directory. Run the extracted scripts and go through the included terms of agreement. You will get some files like "extract-***.sh" in you home directory, run them one by one like
$ ./extract-****-**.sh**
run make command again.
hope this will take care of the issue you have.
Happy coding.

EGL display not valid in Native Activity on Android

I have the following Project I am working on. I am trying to do a simple 2D TriandleFan box.
However, when I run the project the following line fails...
this->display = display;
I can't see why it is failing can anyone else see it?

Using pjsua for android

Greetings to everyone!
I'm trying to compile pjsua using the following branch:
http://svn.pjsip.org/repos/pjproject/branches/projects/android/. I've
tried to do a push (adb push pjsua /data/local/) to my Android-sdk
emulator but, when I've tried to execute it via adb shell, the Android
LogCat gave me the following SIGFAULT error: where am I wrong? Thanks
in advance.

EDIT 1: I must remark that I already know solutions such as csipsimple. Anyway, I'm interested to resolve my cross-compiling issue with Android-ndk's tools.

Why not trying to use an android device instead?
I red in the android website that the android simulator is usually not compatible with sip stacks.

sample program does not execute always after making changes to dalvik jit

I have made some changes to dalvik jit by changing the jit table structure from chained array to a combination of hash table and B-tree. Now when i execute a sample java program which is
public class prog {
public static void main(String args[])
{
long start=System.currentTimeMillis();
int sum=0;
for(int i=1;i<10;i++)
{
for(int j=0;j<10;j++) {
long h=getKey();
System.out.println("key : "+h);
}
}
System.out.println("time : "+(System.currentTimeMillis()-start));
}
public static long getKey()
{
Random rand=new Random();
long key = rand.nextLong();
if(key<0)
return -key;
else
return key;
}
}
using dalvikvm -cp prog.jar prog after pushing libdvm.so(built after changes made to JIT) into the android emulator. Sometimes the program runs perfectly and sometimes it results in segmentation fault. When I checked the logs this is the error shown :

what could the possible problem be? Is it memory related problems or bug related to JIT code changed?
Thanks
