Hi Chris Conlon,
I used your library in android and in this API
WOLFSSL_API int wolfSSL_CTX_load_verify_locations(WOLFSSL_CTX*, const char*, const char*);
your calling ProcessFile() method and trying to open file with file name but its failing, due to Android is not allowing to open file but if you can take file descriptor then FOPEN will work or use asset manager in NDK then it will be easily.

example:-
instead of fname, if you had file descriptor it will work in android or you use -DWOLFSSL_JNI flag and ask for AssetManager to process the file from assets directory it will also work.

file = XFOPEN(fname, "rb");
if (file == XBADFILE) return WOLFSSL_BAD_FILE;
if (XFSEEK(file, 0, XSEEK_END) != 0) {
XFCLOSE(file);
return WOLFSSL_BAD_FILE;
}
sz = XFTELL(file);
XREWIND(file);
