  4. Hi,
    thanks for the code.
    I am interested running this example for learning purposes.
    I am a newbie, so can you please post the main.xml ?
    Because eclipse finds error (line:19 PDFFromServerActivity.java).
    Please answer, it will help a lot.
    Thanks in advance.

  5. Sorry for the previews comment, i used the default main.xml, eclipse didnt find any errors, but when i run the app it closes with unexpected error.

    (Unfortunately, PDFFromServerHasStopped)

    Also i tried changing the url with a working one.
    Can you help me?
    Thanks.
