                    context,                                                                      
                    "pdf_url",                                // PDF URL in String format
                    "Pdf title/name ",                        // PDF Name/Title in String format
                    "pdf directory to save",                  // If nothing specific, Put "" it will save to Downloads
                    enableDownload = false                    // This param is true by defualt.
                )
            )
        } 

Java

        open_pdf.setOnClickListener(view -> {
            startActivity(
            
            // Opening pdf from assets folder 
            
                    PdfViewerActivity.Companion.launchPdfFromPath(
                            this,
                            "file_name.pdf",
                            "Pdf title/name",
                            "assets",
                            false,
                            true
                    )
            );
        });

That's pretty much it and you're all wrapped up.

    <item name="pdfView_backIcon">@drawable/ic_arrow_back</item>
    ...
</style>
