If API >=21 you can use PDFRenderer to create a bitmap of each page, but its only viewable, not editable. Here is an example i made up on the fly, lacking navigation buttons, but those shouldn't be to hard to implement.

PdfRenderer renderer = new PdfRenderer(ParcelFileDescriptor.open(new File("/path/to/file.pdf"), 
            ParcelFileDescriptor.MODE_READ_ONLY));
    PdfRenderer.Page page = renderer.openPage(0);
    Bitmap bitmap = Bitmap.createBitmap(page.getWidth(), page.getHeight(),
            Bitmap.Config.ARGB_8888);
    page.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);
    imageView.setImageBitmap(bitmap);
    page.close();
    renderer.close();

Edit

PdfRenderer requires a local file for the FileDescriptor. So in turn viewing through the "cloud", to my knowledge, isnt possible with this approach.
