The page I am working on has a javascript function executed to print parts of the page. For some reason, printing in Safari, causes the window to somehow update. I say somehow, because it does not really refresh as in reload the page, but rather it starts the "rendering" of the page from start, i.e. scroll to top, flash animations start from 0, and so forth. The effect is reproduced by this fiddle: http://jsfiddle.net/fYmnB/ Clicking the print button and finishing or cancelling a print in Safari causes the screen to "go white" for a sec, which in my real website manifests itself as something "like" a reload. While running print button with, let's say, Firefox, just opens and closes the print dialogue without affecting the fiddle page in any way. Is there something with my way of calling the browsers print method that causes this, or how can it be explained - and preferably, avoided? P.S.: On my real site the same occurs with Chrome. In the ex
I love when you guys respond with fancy paragraph that boils down to "No, that's COMPLETELY impossible... and you sir are an idiot for asking. Instead, you should change architecture of your application, just so my answer can be relevant".
ReplyDeleteEspecially in situations when there is a simple answer to what person is asking - if anyone wants to generate PDFs on Android device, here is how to do it:
http://sourceforge.net/projects/itext/ (library)
http://www.vogella.de/articles/JavaPDF/article.html (tutorial)
http://tutorials.jenkov.com/java-itext/image.html (images tutorial)
I would recommend you set up a Web service and have the device use the Web service to generate the PDF. PDF creation is going to be very slow on a device, even if you can find a Java library for it that works on Android. You also then have greater flexibility in terms of languages and libraries for the PDF creation (e.g., use Prawn for Ruby), since you're doing the PDF creation on a server.
ReplyDeleteI recently faced a similar issue and decided to port an older version of iText (http://sourceforge.net/projects/itext/) to be able to create pdf's. I successfully ported the core of the last LGPL version of iText with some code from bouncycastle and Apache Harmony to Android.
ReplyDeleteI released a first alpha of the project at http://code.google.com/p/droidtext/. It is available under LGPL like the projects it is based on.
I am already using it in on of my projects and it works very well so far.
Check it out. Any feedback is welcome
Late, but relevant to request and hopefully helpful. If using an external service (as suggested in the reply by CommonsWare) then Docmosis has a cloud service that might help - offloading processing to a cloud service that does the heavy processing. That approach is ideal in some circumstances but of course relies on being net-connected.
