Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.
The HTML to PDF conversion API accepts different sources, such as HTTP/HTTPS URLs, HTML strings, and everything that can be loaded in a WebView.
To convert a link URL to PDF, simply:
public void convertFromUrl(Context context, String url, Uri folder, String outputFileName) HTML2PDF.fromUrl(context, url, folder, outputFileName, new HTML2PDF.HTML2PDFListener() @Override public void onConversionFinished(String pdfOutput, boolean isLocal) // Handle callback when conversion finished > @Override public void onConversionFailed(String error) // Handle callback if conversion failed > >); >
To convert an HTML string to PDF, simply:
public void convertFromHtml(Context context, String baseUrl, String htmlSting) HTML2PDF.fromHTMLDocument(context, baseUrl, htmlSting, new HTML2PDF.HTML2PDFListener() @Override public void onConversionFinished(String pdfOutput, boolean isLocal) // Handle callback when conversion finished > @Override public void onConversionFailed(String error) // Handle callback if conversion failed > >); >
where myBaseUrl is the URL to use as the page's base URL. If null defaults to about:blank and myHtmlData is a String of data in the UTF-8 encoding. Click here for more info.
If none of the above fit your needs, you can also pass in a WebView directly for conversion:
public void convertFromWebView(WebView myWebview) HTML2PDF.fromWebView(myWebview, new HTML2PDF.HTML2PDFListener() @Override public void onConversionFinished(String pdfOutput, boolean isLocal) // do something with the PDF output > @Override public void onConversionFailed(String error) // handle error > >); >
