Let me use my telepathic abilities(I have to since you did not provide the error information)...
You are getting ArrayIndexOutOfBoundsException. And there is a long list of issues here: - i<=daty.length - This one will always result in an ArrayIndexOutOfBoundsException - using datx[i+1] will cause ArrayIndexOutOfBoundsException if used without thought - And the list goes on an on, but you would not want to hear it... http://goo.gl/OkYcW On Jun 22, 1:16 am, Vini <vinic...@gmail.com> wrote: > Hi, I want a funtion graph in android. > I have two arrays (x e y) and want graph with draw line, but throws me > an error "the application has stopped unexpectedly ".
