How to use the library?

Now you have integrated the library in your project but how do you use it? Well its really easy just launch the intent with in following way:


open_pdf.setOnClickListener {
            // Use 'launchPdfFromPath' if you want to use assets file (enable "fromAssets" flag) / internal directory
                PdfViewerActivity.launchPdfFromUrl(           //PdfViewerActivity.Companion.launchPdfFromUrl(..   :: incase of JAVA       
                    "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.


        open_pdf.setOnClickListener(view -> {
            // Opening pdf from assets folder 
                            "Pdf title/name",

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

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