Make md5 calcation base on ppsspp

[sum2012]

Hi

I want to port
https://github.com/jixunmoe/mfcDuDownloadCodeGenerator
Project into Android.
(I have ported to Delphi https://github.com/sum2012/DelphiDuDownl...eGenerator but don't work in Android)

It need full file of md5, first 262144 byte of md5
and file size.

Now I can compile ppsspp in Android Studio so that I want to make md5 calcation base on ppsspp

UI::EventReturn GameScreen::OnDoMD5(UI::EventParams& e) {
auto chrs = gamePath_.c_str();
MD5string = md5file(chrs);
...............


std::string md5file(const char* filename) {
std::FILE* file = std::fopen(filename, "rb");

std::FILE* file = std::fopen don't work in Andorid.
Anyone can help me?Thanks
