Convert word and excel to html on android

Question

I would like to convert word and excel documents to html to show them in the browser in my android app.

I found apache poi library, but it converts practically only text without object like forms, diagrams, wordart etc. Or is it possible and I forgot something?

I found also apache tika, but when I added that library to my project I could'nt compile it because of java heap space error (I have in my eclipse.ini file set Xms768m and Xmx2048m). I tried also to load that library at runtime and tried to use dx tool, but I got outofmemory exception.

What could I do with that or is there any possibility to show office documents in the android app?

There are some libraries with which you can handle MS Office documents, what do you think about saving them as .pdf and then showing them? — Andres L, Mar 28 '13 at 10:24
Saving them as a pdf could be good. Could you give me any examples of such libraries? — Bartosz Bialecki, Mar 28 '13 at 10:36
Maybe check the export function from http://www.docx4java.org — Andres L, Mar 28 '13 at 10:39
Ok, thank you, I will check that, but I think it does not support old doc and xls format. — Bartosz Bialecki, Mar 28 '13 at 10:43
refer to the `Handling legacy binary .doc files` part of their getting started. http://www.docx4java.org/svn/docx4j/trunk/docx4j/docs/Docx4j_GettingStarted.html — Andres L, Mar 28 '13 at 10:46

To handle the OOM error while using the dexer:

there is a dx script used during the builds and it sets a default heapsize for the dexer. The script lives here:

$ANDROID_SDK/build-tools/dx (or dx.bat depending on OS).

There is a section in there that looks like this:

# By default, give dx a max heap size of 1 gig. This can be overridden
# by using a "-J" option (see below).
defaultMx="-Xmx1024M"

# The following will extract any initial parameters of the form
# "-J<stuff>" from the command line and pass them to the Java
# invocation (instead of to dx). This makes it possible for you to add
# a command-line parameter such as "-JXmx256M" in your scripts, for
# example. "java" (with no args) and "java -X" give a summary of
# available options.

javaOpts=""

Maybe try changing javaOpts to -Xmx2048M or something like that.
