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() 时将下载并安装它。正在下载并安装动态模块，但字体未在 PDF 中呈现。这些字体可用于设置应用程序视图中文本的字体，但它们不会在 PDF 中呈现。为什么？

谁能帮我解决这个问题？它在调试模式下完美运行。

SomeActivity.java：无法使用此代码进行渲染。资产文件被下载并保存到资产文件夹中，该文件夹再次在 App View 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，使用上述行 PDF 正在使用新下载字体的默认字体内嵌呈现。但在借记模式下，此代码运行良好。

@Override
public void onChooseFontClicked(View v) {
    String fontModule = "module_font";
    if (splitInstallManager.getInstalledModules().contains(fontModule)) {

        AppUtils.showToast(this, "Already Installed module.");
        showFontStyleFragment();

    } else {
        requestInstall(fontModule);
    }

            .addModule(moduleName)
