Introduction

OpenOfficeQuestion:How can you bring OpenOffice onto mobile devices?

There are several efforts

LibreOffice on Android/iOS

The Document Foundation Blog, October 14, 2011LibreOffice 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.

Solutions exist, but none are not fully working yet.

So we wait

Wait

OfficeBut, if we only want some client applications?

(2010-2011)WebOpenOfficeIn the past two years (2010-2011), I tried demonstrating OpenOffice onto mobile using mobile-web applications.

Impress

For Impress, a remote presentation controller (2010 COSCUP)

For Writer, a simple document processing system


Calc

For Calc, a remote chart report generator

AndroidWhat about Android?

Android is Free

Android

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.

Android is Accessible

Android is available on Linux/Windows/MacWhere I can work on my free daily Debian Linux desktop PC.

Android is Java

OpenOffice SDKJava UNO

OpenOffice has official Java UNO libraries shipped with OpenOffice SDK.

Android is Java

.jar

Actually, you only need these four OpenOffice UNO .jar libraries.juh.jar

jurt.jar

ridl.jar

unoil.jar

But, life is not always easy

Conversion to Dalvik format failed with error 1.

DalvikUNO Java .jarDalvik class file converter failed to convert the UNO Java libraries!?

GoogleAndroid UNOI Googled everywhere.Since few people tried to build OpenOffice UNO application on Android, nobody has ever discussed this before.

Solution?

Java .jarzipLuckily, we know that Java .jar files are simply zipped files.

% 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; abortingfailed in unoil.jar%

unoil.jarGood try!We know the problem lies within unoil.jar now.

% 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: 128Caused 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; abortingfailed at com/sun/star/datatransfer/dnd/DNDConstants.class%

com/sun/star/datatransfer/dnd/DNDConstants.classcom.sun.star.datatransfer.dnd.DNDConstantsSo the problem lies within com/sun/star/datatransfer/dnd/DNDConstants.class,which belongs to com.sun.star.datatransfer.dnd.DNDConstants.

We don't need it for our application.So lets remove it for now.

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

It works now!
