Hello. I use this library in my android application: https://github.com/lzyzsd/CircleProgress
It is licensed
"DO WHAT THE FUCK YOU WANT TO PUBLIC LICENSE"
Do I need to indicate this text of the license and the author in the
"О программе" window?
Or, this license assumes the use of the library without mentioning the author.
Yes, it is necessary if you plan to distribute the program in countries that have adopted the Berne Convention (among which there are the Russian Federation and the United States).
The mention of authorship – is the realization of the right of authorship relating to the non-exclusive rights.
License mention – an indication of the conditions under which a copy of the library was transferred to you. The fact is that nothing prevents the author from distributing the same library under different licenses to different people and businesses.
Accordingly, with further distribution (if the license permits it), you not only have to provide users with conditions and permissions, but also indicate that this very distribution is generally legal.
