I'm doing some work in art based on Android5.1, and I want to add a variable in Array class in Array.h(art/runtime/mirror/Array.h).
But when I add a "uint32_t tag" in the class, the system in emulator can not start up. So how can I add some variable in Array.h in Android5.1?
The crash log is like:

Kaiyuan Zhao,
First of all, I am not sure why you would want EVERY array to have your tag, but the question is not really WHY, it is HOW.
Here is the HOW: You would need to change it in the .h file, and then go through the entirety of the android source code and change every call of an array element to take into account your change. This is a tedious and, in my thoughts, un-worthwhile task. Anyway, that is the HOW. It might be easier to write a script to take care of this for you in the end.
If you still want to do something like this, I wish you good luck and speedy grepping. Also, if you do come up with some sort of script, I would be very interested in seeing it. It would be a useful script in other situations as well.
