resource file

Hello,

I try to port my game to android.
It works fine on linux and Windows but I have problem to open my resource file with the sdl api.
The api seems to read only 6 Bytes.
Here is the simple test code I use:
SDL_RWops* res = SDL_RWFromFile(path, "rb");
    SDL_RWseek(res,0,RW_SEEK_END);
    int fileSize = SDL_RWtell(res);
#ifdef ANDRO
    __android_log_print(ANDROID_LOG_VERBOSE, APPNAME, "fileSize %d \n", (int)fileSize);
#endif
    printf("fileSize %d \n", (int)fileSize);

You can try with the file attached.
Thanks.

What path are you using?
Comment 3 lctmp2 2014-05-19 14:20:03 UTC 
I simply use «res.bin» because my file is in the assets directory.
Comment 4 Gabriel Jacobo 2014-05-19 14:28:55 UTC 
Did you extract the APK and verified the file is in there and it's contents look ok? Which device are you having problems with?
Comment 5 lctmp2 2014-05-19 15:23:16 UTC 
Yes, I have opened the .apk to verify the size of the file. I use an Acer  liquid e2 v370 with android 4.2.2.
Comment 6 Philipp Wiesemann 2015-06-09 20:28:02 UTC 
SDL_RWseek() returns -1 if it failed. This could also be checked.

Or SDL_RWsize() could be used.
Comment 7 Sam Lantinga 2017-08-14 13:08:02 UTC 
Sylvain, can you confirm that you can just drop a file in the apk and read it without specifying the path?
Comment 8 Sylvain 2017-08-14 13:37:33 UTC 
This is working.
make sure your asset file is in ./assets/


       const char *path = "background.jpg";
       SDL_RWops* res = SDL_RWFromFile(path, "rb");
       int r = SDL_RWseek(res,0,RW_SEEK_END);
       int fileSize = SDL_RWtell(res);
       some printf("tell %d filesize", fileSize);
Comment 9 Sam Lantinga 2017-08-14 14:13:35 UTC 
I'm closing this for now. Please reopen it if you have a file in the assets directory that you can't open using the SDL API.

Thanks!
