cocos2dx的android版FileUtils的坑

FileUtils::Status FileUtilsAndroid::getContents(const std::string& filename, ResizableBuffer* buffer)
{
    static const std::string apkprefix("assets/");
    if (filename.empty())
        return FileUtils::Status::NotExists;

    string fullPath = fullPathForFilename(filename);

    if (fullPath[0] == ‘/‘)
        return FileUtils::getContents(fullPath, buffer);

    string relativePath = string();
    size_t position = fullPath.find(apkprefix);
    if (0 == position) {
        // "assets/" is at the beginning of the path and we don‘t want it
        relativePath += fullPath.substr(apkprefix.size());
    } else {
        relativePath = fullPath;
    }
...
}
