I tried to use arm-eabi-addr2line with address 0001072a than i got the following result

/usr/local/google/home/digit/android/main/cupcake/android/bionic/libc/unistd/brk.c:45

I am getting this for all platforms: Android 1.6, 2.1, and 2.2.

My program getting crash when i am trying to retrieve the values from buffer which is populated in JNI side.

Here is following code I am using to get the value from JNI side populated buffer.

for(int j = 0; j < count; j++)
{
    len = outBuf.getInt();
    CharBuffer cbuf = outBuf.asCharBuffer();
    CharSequence cS = cbuf.subSequence(0, len);
    wordsPage[j] = cS.toString();
    outBuf.position(outBuf.position()+ (len*2));
}

And could you please tell me any full proof mechanism to share the memory between Java and JNI.

What's your wordsPage size? Any index out of bounds issue there? Suggest you enable dalvik.vm.checkjni=true and see more information.
