EDIT: Jump to the conclusion and partial fix here

I open this thread to ask if someone else has encountered this issue.
Setup everything as in https://www.b4x.com/android/forum/t...nal-material-design-components.58893/#content
Try download FixedTabsExample2_00.zip file, and set everything up for AHViewPager library.
Update any SDK and try to build example above with "FixedTabIcon" from @corwin42 who's work btw is tremendous.
The error is below
** Activity (main) Pause, UserClosed = true **
** Activity (main) Create, isFirst = false **
main_activity_create (java line: 348)

I know my system is wrongly setup, but I don't know what to do, I tryed so many things (in reality I have a huge app who use some layouts file with AHViewPager views that throw this similar error when loaded, but previously it worked just fine until some sdk? update)

That I'm too stupid.

A simple recompile of the library against the latest 28.0.0 support libraries did the trick. I thought I had done this but it seems I made a mistake and did not copy the new library correctly. So I always tested with the old one which crashed.

Sorry that it took so long to fix this issue.
