This screenshot confirms that you have the x and y coordinates the wrong way round, as I mentioned in my comment earlier. The coordinates are in degrees, just assume a CRS of 4326 to start with. Don't worry about projections for now. Once your points are showing over Croatia, then you can re-project into a suitable local projection. x=45, y=14 will show up ...
You can use the Geometry service project method to do this projection. Since it is an asynchronous call, it will not be as responsive as the example (which is being calculated in the browser). The core code to change is in showCoordinates: Working example: https://jsfiddle.net/gavinr/f8e62ajc Edit: John Gravois has a blog post explaining this exact problem ...
If you have the data in Excel you'd probably do better doing the calculation in Excel! The Haversine formula (find it here: http://www.movable-type.co.uk/scripts/latlong.html) will give you the distance between two pairs of latitude and longitude.
The coordinates you have are in WGS 84, just note Zagreb's coordinates: 45.8167° N, 15.9833° E. Have in mind that's in degrees and it is a geographic coordinate system. If you do not know exactly the difference between a geographic coordinate system and a projected coordinate system let me know and I can link you to a good website explaining it. Just ...
Pretty much all android phones will record the GPS coordinates of a picture in the EXIF data, so you should already have that feature. http://www.digital-photo-secrets.com/tip/1401/how-do-you-find-the-gps-coordinates-of-your-photos/ http://www.phonearena.com/news/How-to-enable-or-disable-photo-and-video-geo-location-on-Android_id62637 ...
Use the 'Add Delimited Text File' (It has the icon of an apostrophe). You then specify the lat/long coordinates in the x/y fields and those points will be rendered. You then right click the layer and save as a shapefile.
