How to dump the specified java object from the memory of Android ART

Question

I want to dump the specified java object from ART memory(/proc/{pid}/mem)

Python code

def read_mem_vma(pid):
    vma_range_list = []
    f = open(f'/proc/{pid}/maps')
    for line in f:
        if 'rw' in line:
            range_ = tuple(int(s, 16) for s in line.split()[0].split('-'))
            vma_range_list.append(range_)
    return vma_range_list


def travel_mem(pid):
    art_java_object_header_size = 10
    vma_range_list = read_mem_vma(pid)
    f = open(f'/proc/{pid}/mem', 'rb')
    for start, end in vma_range_list:
        for addr in range(start, end, 4):
            f.seek(addr)
            header_bytes = f.read(art_java_object_header_size)
            if is_java_obj_header(header_bytes):
                parser_java_obj(header_bytes, f, 'class Student')


def is_java_obj_header(header_bytes):
    # return header_bytes[xx]  == magic_number
    pass


def parser_java_obj(header_bytes, f, which):
    # if header_bytes[xx] == which:
    #     obj_data_len = header_bytes[offset]
    #     obj_data_bytes = f.read(obj_data_len)
    #     struct.unpack()  ...
    #     return {"name": "jack", "no": 110}
    pass


if __name__ == '__main__':
    pid = 'target_app_pid'
    travel_mem(pid)

I know that the key is the object header and the memory layout of the object. How to improve these codes? Which documentation can I refer to?

Don't consider Hooking or Injecting.

My python code was run in adeb(debian fs).any language is welcome.
