使用动态功能模块：下载并安装在Asset文件夹中的字体，但不是在PDF-VIEW中呈现，而在APP-UI-VIEW中呈现？

问题描述

我创建了一个动态功能模块（由资产，字体和文件组成），当用户点击onChooseFontClicked（）时将下载并安装该模块。正在下载并安装动态模块，但字体未在PDF中呈现。这些字体可用于在应用程序视图内设置文本的字体，但它们不会在PDF中呈现。为什么？

有人可以帮助我解决这个问题吗？ 它在DEBUG模式下运行正常。

SomeActivity.java：无法使用此代码进行渲染。 资产文件已下载并保存到资产文件夹，该文件夹再次在“应用程序视图”中呈现，但不在PDF视图（iTextPDF）中呈现。

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);

在发布模式下，使用上述几行PDF会使用新下载字体的默认字体显示出来。但是在借记模式下，此代码可以正常工作。
