Answer 1

i have tackled that error. I just changed dependencies compile 'com.jjoe64:graphview:4.2.2' to compile 'com.jjoe64:graphview:4.0.1' in build.gradle.

Answer 2

current version is 4.2.1 so you should change it to

compile 'com.jjoe64:graphview:4.2.1'

Answer 3

I have resolved this problem by adding adding Graphview.3.0.0 jar . Initially i was working with Graphview.4.2.1 so same error was coming , but when I add lower version , everything was working well .
