http://androidforums.com – Is it possible inside ondraw to have a single point of origin for 100 lines ? The length of each line will be user defined from a different activity via intent. The angle of each line is 360/100. essentially i need to build a ray ( angl*lenght(var) for each of my 100 lines. I am having a difficult time inside the android reference locating a method to accomplish this. Anyone have any advice? (General)
