Using SDL_RWFromFile(..., "wb") without file path, only file name

SDL Development

Where SDL_RWFromFile writes this file on android?

char line[] = "New creatable file input";
SDL_RWops *io = SDL_RWFromFile("hello.txt", "wb");
SDL_RWwrite(io, line, sizeof(line), 1);
SDL_RWclose(io);

In my case it writes into files directory.
