hi Fadden,
thanks for the reply
I am able to proceed swapMap() function by fixing an endian issue in that
function.
Fix: pMap->size has to be converted to big-endian before assigning it to
count variable.
Now I have another issue in crossVerifyEverything() with
"kDexTypeClassDefItem" switch-case. It is becoming increasingly difficult to
debug this as this is tightly coupled to dex file-format. I hope I can get
some pointers into fixing this issue.
Thanks
Anand
