Convert Html into PDF using webview : can not create multiple pages

Question

I'm working on one functionality in my current application, in which i want to convert html file into pdf format and save it in storage.

for that i'm using Printing HTML documents PdfDocument right now I am not keen in using iText because they need you to buy a commercial license. i want to achieve this printing with webview.

first i'm struggling with image display and proper display content which i achieve by changing my code and html file now i cannot create multiple pages in pdf. i can create only one page with very small images and content in size and all in one page instead of diving in other pages.

i tried to follow some link but couldn't understand much.

how to get whole content of Web View to generate PDF file in android?

Creating PDF from WebView truncates PDF

Question: my approach is right!? How do I alter createPdf() so that it gives me a PDF with multiple pages. Suppose my HTML is huge and it doesn't fit in one A4 page. Do I need to manually create separate pages using PdfDocument.Page (canvas) and startPage() and finishPage()? How would I split the WebView based on page size? Is there any automatic way of creating pages?

Edit: i tried to change imgsrc, i download and save image in assets folder

    mWebView.loadDataWithBaseURL("file:///android_asset/", htmlDocument, "text/HTML", "UTF-8", null);

my code is as below:

private void doWebViewPrint() {
        mWebView.setWebViewClient(new WebViewClient() {

            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                Log.i(url, "page finished loading " + url);
                createWebPrintJob(view);
                mWebView = null;
            }
        });

        // Generate an HTML document on the fly:
        String htmlDocument = "my html file content";
        mWebView.loadDataWithBaseURL(null, htmlDocument, "text/HTML", "UTF-8", null);

    }

    private void createWebPrintJob(WebView webView) {
        String jobName = "pdfDocument";
        PrintAttributes attributes = new PrintAttributes.Builder()
                .setMediaSize(PrintAttributes.MediaSize.ISO_A1)
                .setResolution(new PrintAttributes.Resolution("pdf", "pdf", 600, 600))
                .setMinMargins(PrintAttributes.Margins.NO_MARGINS).build();

        File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM + "/PDFTest/");
        PdfPrint pdfPrint = new PdfPrint(attributes);
        pdfPrint.print(webView.createPrintDocumentAdapter(jobName), path, "output_" + System.currentTimeMillis() + ".pdf");
    }


public class PdfPrint{

    private static final String TAG = PdfPrint.class.getSimpleName();
    PrintAttributes printAttributes;

    public PdfPrint(PrintAttributes printAttributes) {
        this.printAttributes = printAttributes;
    }

    public void print(final PrintDocumentAdapter printAdapter, final File path, final String fileName) {
        printAdapter.onLayout(null, printAttributes, null, new PrintDocumentAdapter.LayoutResultCallback() {
            @Override
            public void onLayoutFinished(PrintDocumentInfo info, boolean changed) {
                printAdapter.onWrite(new PageRange[]{PageRange.ALL_PAGES}, getOutputFile(path, fileName), new CancellationSignal(),
                        new PrintDocumentAdapter.WriteResultCallback() {
                    @Override
                    public void onWriteFinished(PageRange[] pages) {
                        super.onWriteFinished(pages);
                    }
                });
            }
        }, null);
    }

    private ParcelFileDescriptor getOutputFile(File path, String fileName) {
        if (!path.exists()) {
            path.mkdirs();
        }
        File file = new File(path, fileName);
        try {
            file.createNewFile();
            return ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_WRITE);
        } catch (Exception e) {
            Log.e(TAG, "Failed to open ParcelFileDescriptor", e);
        }
        return null;
    }


}
