Drawtool of ArcGIS for Android getting started Program

ArcGIS for Android is a mobile development kit developed by ESRI Based on the Android platform. Like ArcGIS for iOS and ArcGIS for Windows Phone, ArcGIS for Android accesses the rest Services released by ArcGIS Server, including dynamic services, slicing services, element services, and other map services, query, identify, GP, and other spatial analysis services.

ArcGIS for Android provides good development materials, including api reference and sample. To facilitate development, ArcGIS plugin for eclipse is also provided to create a project based on ArcGIS for Android. As for how to configure the development environment, how to use ArcGIS for Android SDK to achieve the basic functions of MobileGIS, you can refer to the ox magic king for Android ArcGIS series of technical articles (OX magic king blog: http://blog.csdn.net/warrenwyf ).

After learning a little about ArcGIS for Android, I found that the response to the gesture event in development is a matter of time, so I wrote a get started program called drawtool. Drawtool is a tool class that can draw points, lines, rectangles, polygon, and circles. It is encapsulated in a simple way to meet General drawing requirements. Through this program, you can better understand how to handle various gesture events in ArcGIS for Android. The drawtoolactivity. Java in the program shows how to call drawtool.
