Good morning,
after updating B4a to version 10.70 the MaterialDateTimePicker library gives me the error :

I've tried to put on tab Files the Font and to initialize it on Main Activity, but the error persist.

Any suggestions?

Best regards

I had the same problem, without using MaterialDateTimePicker, but only importing png files that were needed for the layout. Despite having the file shape_01.png in the Files folder, even having synchronized the folder, clean project, etc it always gave me the same error. I had to rename the file, and re-enter it

I did not have the Roboto font, I had to add it later because of the error. I tried putting it in both Project/Files and Project/Files/fonts, but to no result ...
Any suggestion?

No. As the lib is from 2016 i know i do not have the source anymore. I suggest not to use the lib any longer if it does not work.
I have the same problem and I have used this library in an application for 3 years, now I must replace this library and make an update to all my clients
