android - Using Dynamic Feature Module: Fonts downloaded and installed in Asset folder but is not rendering in PDF-VIEW but renders in APP-UI-VIEW?

Question

I created a dynamic feature module (consists of assets, fonts, and files) which will be downloaded and installed when the user taps onChooseFontClicked(). The dynamic-module is being downloaded and installed, but the fonts are not rendering in the PDF. These fonts can be used to set typeface of the text inside app view but the do they do not render in PDF. Why?

Can anyone help me regarding this issue? It is working perfectly in DEBUG mode.

SomeActivity.java: Unable to render using this code. Assets file is downloaded and saved to the assets folder which again is rendered in App View but not render in PDF view(iTextPDF).

String downloadedAssetsName = "assets/fonts/fontName.ttf";
BaseFont bFont = BaseFont.createFont(downloadedAssetsName, "UTF-8",BaseFont.EMBEDDED);
Font urFontName = new Font(bFont, 12);
Paragraph createdAtparagraph = new Paragraph("Some Data", urFontName);

In release mode, Using above lines PDF is rendering using default font inlace of new downloaded font. But in debit mode this code is working perfectly.
