Research direction
Reproduce the intermittent hook failure with ShadowHook 1.0.9 on the stated Android 13 arm64 device and game. Compare the libil2cpp.so address from getModuleBase plus the offset with the address from AKGetBaseAddress, and check the timing of library loading and hook installation. Done means identifying whether the base-address lookup or ShadowHook causes the missed hook and documenting the evidence.

Describe the Bug
不知道为啥，hook一款游戏(com.olzhas.carparking.multyplayer2 版本名0.3.6.06283941)，有时候能进hook函数，有时候没进来，
先使用线程等待libil2cpp.so加载进来后hook getModuleBase + 偏移量
static void* getModuleBase(char* module_name, char* moduleFullPath)
{
char filename[256];
snprintf(filename, sizeof(filename), "/proc/self/maps");
FILE fp = fopen(filename, "r");
void addr=0;
if (fp != NULL)
{
char line[1024];
while (fgets(line, sizeof(line), fp))
{
if(strstr(line, module_name) && (strstr(line, "r--p")|| strstr(line, "r-xp")))
{
LOGE("getModuleBase：line=%s", line);
sscanf(line, "%[^/]%[^\n]", moduleFullPath);
char pch = strtok(line, "-");
addr = (void)strtoul(pch, NULL, 16);
if (addr == 0x8000){addr = 0;}
LOGE("getModuleBase：找到%s(%s)，base_addr=%p", module_name, moduleFullPath, addr);
break;
}
}
fclose(fp);
}
return (void)addr;
}
但我使用AndHook每次都可以进hook函数，唯一区别就是基址用AKGetBaseAddress获得后 + 偏移量，不知道是shadowhook问题还是基址获得有问题，能否提供点帮助，非常感谢
