PrefaceThe feature drawing and editing of the mid-line surface of mobile GIS project is the most common operation, and the ArcGIS Runtime SDK for IOS comes with the Agssketchlayer class to help users to quickly implement the feature drawing and graphic editing. However, in the ArcGIS Runtime SDK for Android version does not provide similar functionality, the implementation process is relatively complex. (10.2.8 and the following versions require a

Scalable android repackaging ToolToday I checked out the original packaging tool. I learned some technologies. Then git found a similar project code for research. I think it will be much faster to create a script language. Programmers often do not need to package one after another. For programmers, they only need to use a few pieces of code to describe what they do. Therefore, we should write out the repeti

FPS is one of the main indicators of graphic performance. Some Android applications have the function of displaying FPS, such as Bsplayer, Skype, and Antutu. However, most applications do not provide the function of displaying FPS. In addition, applications often provide the update rate of applications, which is not equal to the update rate seen by end users, because more than one application is displayed on the screen. We know that every app in
