[GraphHopper] Where is the Grapphoper.jar (Android)

[Muhammad Babar]

Peter one thing i can't understand is

 boolean greaterOrEqKitkat = Build.VERSION.SDK_INT >= 19;
        if (greaterOrEqKitkat)
        {
            if
(!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
            {
                logUser("GraphHopper is not usable without an external
storage!");
                return;
            }

            mapsFolder = new
File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),
                    "/graphhopper/maps/");
        }

 mapsFolder = new
File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS),
                    "/graphhopper/maps/");

Why this for kitkat or greater? why not this mapsFolder = new
File(Environment.getExternalStorageDirectory(), "/graphhopper/maps/");

Environment.DIRECTORY_DOWNLOADS does this mean for kitkat or higher the map
files and routing data should be in Download directory? Can you please
explain why you are doing this?
