hello, Emmanouil!

how can I help you today?

Hi :-)

Nice to virtually meet. I'm a huge fun.

thanks!

I would like to know, if you know any Android lib, that have the ability to show the documents on the device within the application, and do it offline. In particular we are interested to show MS Office files (specifically doc/docx, xls/xlsx and ppt/pptx formats).

I think that there are commercial libraries for this

a Google search on android docx library turns up a couple

outside of those, if you have a hundred or so developer-years, you will need to write your own

that may also involve paying Microsoft some licensing fee for the formats, as I do not know if they are open

I do not want actually to re-invent the wheel, since my company would like to publish the app at the end of that month

if you cannot use existing commercial libraries, you will be lucky if you can publish the app within five years

the only thing you could do within a month is use an existing library or switch to HTML (using something else to convert those file formats to HTML)

another within-a-month possibility would be to find a suitable commercial PDF rendering library, then use that (and something else to convert those file formats to PDF)

Yes, I am afraid I can't avoid that

I am not sure what "that" is

One of the choices you proposed.

um, OK

Thank you for your time! Have a nice day

sorry I could not be of greater assistance

No problem, I have spend 3 full days investigating that issue also. Your opinion values for me a lot. Thank you again. :-)
