It worked before, but now it throws:
android.view.InflateException: Binary XML file line #16: Binary XML file line #17: Error inflating class com.viewpagerindicator.CirclePageIndicator caused by: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x1d`
I've tried to set @color/color_primary values and '#ff00ff' color hex values: the same issue.
As a workaround: I set all needed colors in runtime by calling setFillColor(), setPageColor() and setStrokeColor() respectively.
Library version compile 'com.viewpagerindicator:library:2.4.1@aar'

This happens when you update your gradle version, and this Lib isn't giving any support or having updates for more than 5 years... Despite I tried many other alternatives to keep using it, the best solution was to change it for this one: implementation 'com.github.splatte:ViewPagerIndicator:3.0.0'
More information here: https://stackoverflow.com/a/47785895/6706788 There are other options there (one telling to add "app:" on all attributes of this lib), feel free to try them too if you want, for me, the solution of the alternative lib (a branch) was the only one that worked.
