Threadingtest (TT) The first phase is an Android white box test tool, using offline detection method, based on the protection of User source code, the use of plug-in, fifth-generation coverage and other technologies, for development engineers and test engineers to provide a set of efficient quantifiable, visual communication tools. In contrast to other test tools, TT automatically generates the relationship between test cases and code and function cov

Figure 31 Viewshed example of calling the GP Service
In ArcGIS Android API, it is an interesting example to demonstrate the calling of the GP Service (Viewshed). This example allows users to draw a dot on the screen, then, send a request to call the GP service through the button executed in the upper left corner. When the GP service is successfully called, some polygon a
