Pdf Renderer API Android From URL

I am looking into the PDF renderer API native to Google Android development. I see the following code example in the documentation:

 // create a new renderer
 PdfRenderer renderer = new PdfRenderer(getSeekableFileDescriptor());

 // let us just render all pages
 final int pageCount = renderer.getPageCount();
 for (int i = 0; i < pageCount; i++) {
 Page page = renderer.openPage(i);

 // say we render for showing on the screen
 page.render(mBitmap, null, null, Page.RENDER_MODE_FOR_DISPLAY);

 // do stuff with the bitmap

 // close the page
 page.close();
 }

 // close the renderer
 renderer.close();

I think this example uses from File Object. How I can get this API to work with a URL from a webserver, such as a document from a website? How can I load a PDF natively in an Android app that does not require a download of the file onto the local storage? Something like how you can run the Google docs viewer to open the PDF in webview – but I cannot take that approach because the Google docs viewer is blocked in the environment I am in.

Download the PDF from the server to a local file. Then, use the local file.

AFAIK, you cannot use PdfRenderer that way. It needs a seekable FileDescriptor, and the only way that I know of to create one of those involves a local file.
