Why not adding GetFilesDir() function to get the application's root private storage folder on android system

a function is needed to get the current application folder on adnroid like to get the application’s directory to save private data to a file for the application directly from the SDL on android ? In other words, we need an equivalent of the Java function mContext.getFilesDir().

This function does exactly that: https://wiki.libsdl.org/SDL_AndroidGetInternalStoragePath

I think SDL_GetPrefPath might also give the same dir.
