8. 簡介
Introduction

9. 問題：
如何在行動裝置上用 OpenOffice ？
Question:
How can you bring OpenOffice onto
mobile devices?

10. 開發中的現有專案…
There are several efforts…

11. LibreOffice on Android/iOS
The Document Foundation Blog,
October 14, 2011
“LibreOffice port project to Android and iOS,
based on the voluntary work of Tor Lillqvist, a
SUSE finnish developer know for having ported
GIMP to Windows. The LibreOffice Android and
iOS port has the objective of bringing the office
suite to iPads and Android tablets, and
eventually smaller devices. The user interface
work has yet to start in earnest but the bulk of
the code is compiling.”

13. 有一些方案了，但功能還不完整。
Solutions exist, but none are not
fully working yet.

14. 還要再等等…
So we wait…

15. 等等…
Wait…

16. …

17. 如果，我們只是要簡單的 Office 應用呢？
But, if we only want some client
applications?

18. 前兩年 (2010-2011) ，
我曾試著用 Web 行動應用，
把 OpenOffice 帶到行動裝置上。
In the past two years (2010-2011),
I tried demonstrating OpenOffice
onto mobile using mobile-web
applications.

19. Bringing OpenOffice onto
Mobile Devices
用 Impress 做簡報
遙控器…
For Impress, a
remote
presentation
controller…
(2010 COSCUP)

20. Bringing OpenOffice onto
Mobile Devices
用 Writer 實作簡單
的文件處理流程…
For Writer, a
simple
document
processing
system…

21. Bringing OpenOffice onto
Mobile Devices
用 Calc 做圖表報告
產生器…
For Calc, a remote
chart report
generator…

22. 我還玩了一點魔術（ 2011 COSCUP ）…
And I even tried playing some
magic (2011 COSCUP)…

23. Playing Presentation Magic
發撲克牌…
Dealing poker
cards…

24. Playing Presentation Magic
玩剪刀石頭布…
Playing rock-
paper-scissors…

25. Playing Presentation Magic
跑 CAPTCHA…
Running
CAPTCHA…

26. Playing Presentation Magic
展示即時資訊…
Displaying real-
time
information…

27. OpenOffice UNO API
跨語言網路物件系統
Universal Network Objects

28. 透過 OpenOffice UNO API ，可以很容
易從外部控制 OpenOffice 、變魔術。
OpenOffice UNO API makes it very
easy to control OpenOffice from
outside (and play the magic).

44. 但如果我們想直接做 Office 應用呢？
But, what if we create the client
application directly?

45. 行動 Office 辦公室應用

46. iOS ？不要吧… ^^;
Oh, no!
Not the iOS application!

47. 要玩 iOS ，要先有…
With iOS, you need…
A Mac ($$$)
Developer annual
license fee ($$)
Objective-C

48. 那如果是 Android 呢？
What about Android?

49. Android is Free
每個人都可以自由開發 Android 應用。
想開發自己的程式應用，不用先付權利金。
Android is a system that everyone can
freely develop her/his own toys on it.
You don't have to pay a fee for your own
device.

50. Android is Accessible
Android is
available on
Linux/Windows/
Mac
Where I can work
on my free daily
Debian Linux
desktop PC.

51. Android is Java
OpenOffice SDK 中
正好就有官方的
Java UNO 函式庫
。
OpenOffice has
official Java UNO
libraries shipped
with OpenOffice
SDK.

52. Android is Java
其實只需要下列四個 .jar 檔。
Actually, you only need these four
OpenOffice UNO .jar libraries.
juh.jar
jurt.jar
ridl.jar
unoil.jar

53. 但是花無百日紅…
But, life is not always easy…

56. “Conversion to Dalvik format
failed with error 1.”

57. Dalvik 無法轉換 UNO Java .jar 檔！？
Dalvik class file converter failed to
convert the UNO Java libraries!?

58. 我到處 Google 。
但是很少人做 Android UNO 應用程式，
網路上也沒有什麼討論。
I Googled everywhere.
Since few people tried to build
OpenOffice UNO application on
Android, nobody has ever discussed
this before.

59. 怎麼辦？
Solution?

60. 還好， Java .jar 檔只是 zip 壓縮檔。
Luckily, we know that Java .jar files
are simply zipped files.

61. % for f in *.jar; do /opt/android-sdk-linux/platform-tools/dx --dex $f
|| echo "failed in $f"; done; unset f
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.util.ExceptionWithContext: bogus byte value: 128
…
... 14 more
...while processing ACTION_DEFAULT B
...while processing com/sun/star/datatransfer/dnd/DNDConstants.class
1 error; aborting
failed in unoil.jar
%

62. 幹得好！
所以只有 unoil.jar 有問題。
Good try!
We know the problem lies within
unoil.jar now.

63. % mkdir unoil
% cd unoil
% unzip ../unoil.jar
…
% for f in `find * -name "*.class"`; do /opt/android-sdk-linux/platform-
tools/dx --dex $f || echo "failed at $f"; done; unset f
… (This takes a long time.)
UNEXPECTED TOP-LEVEL EXCEPTION:
com.android.dx.util.ExceptionWithContext: bogus byte value: 128
…
Caused by: java.lang.IllegalArgumentException: bogus byte value: 128
…
... 13 more
...while processing ACTION_DEFAULT B
...while processing com/sun/star/datatransfer/dnd/DNDConstants.class
1 error; aborting
failed at com/sun/star/datatransfer/dnd/DNDConstants.class
%

64. 所以問題是在
com/sun/star/datatransfer/dnd/DNDConstants.class
屬於
com.sun.star.datatransfer.dnd.DNDConstants
So the problem lies within
com/sun/star/datatransfer/dnd/DNDConstants.class,
which belongs to
com.sun.star.datatransfer.dnd.DNDConstants.

65. 還好我們用不到。就刪掉吧！
We don't need it for our
application.
So lets remove it for now.

66. % rm -f com/sun/star/datatransfer/dnd/DNDConstants.class
% rm -f ../unoil.jar
% zip -9 -r ../unoil.jar *
%

68. 成功了！
It works now!
