I have been using ArcGIS SDK from last 2 years and the best thing about this SDK is that it is platform independent for creating apps. It can be used to create apps for any OS such as Windows, Linux or Mac.
Its Geocoding feature provides me the option to search for the destination places using predefined match criteria. The directions and the total drive time are 100% accurate and can be permanently relied upon.
its Maps are visually appealing and it has various rendering options to choose from. It has a rich collection of maps. Elevation data can be used to query questions and get a detailed assessment summary of the same. Review collected by and hosted on G2.com.
Sometimes it is unable to find the imports I use in it. At that point of time, I have to download it and then provide the package so that it can be used. That's the only small issue in this SDK. Review collected by and hosted on G2.com.
