有没有办法从Android应用程序创建PDF文件？

可以在我的Android应用程序中运行java app(jar)吗？因为我需要创建PDF,问题是如果我在android中生成PDF,只能用小图像显示,如果它在很多页面中包含大图像,那将是错误的.所以我想,我可以在java中生成PDF然后包含到Android应用程序中.

如何在Android中从图像文件创建包含多个页面的PDF文件？我从图像创建了一个PDF文件.该PDF文件有一页.这是该图像的一半.在右侧搜索部分被剪切为PDF文件.我使用itext-5.3.4.jar来创建PDF.

    wbviewnews.loadUrl("http://developer.android.com/about/index.html");
   // button for create wbpage to image than image to PDF file

                //Bitmap bitmap = Bitmap.createBitmap(200,200, Config.ARGB_8888);
                Canvas canvas = new Canvas(bitmap);
                canvas.drawPicture(pictureDrawable.getPicture());

                ImageView imgdata=(ImageView)findViewById(R.id.imgdata);
                imgdata.setImageBitmap(bitmap); 

                String filename = "pippo.png";
                File sd = Environment.getExternalStorageDirectory();

                File dest = new File(sd, filename);
                String pdffilename = "pippo.pdf";
