gContactOOo is part of a Suite of LibreOffice and/or OpenOffice extensions allowing to offer you innovative services in these office suites.
This extension gives you access to your phone contacts in LibreOffice / OpenOffice (the contacts of your Android phone).

Being free software I encourage you:

In short, to participate in the development of this extension.
Because it is together that we can make Free Software smarter.


gContactOOo uses a local HsqlDB database of version 2.5.1.
The use of HsqlDB requires the installation and configuration within LibreOffice / OpenOffice of a JRE version 1.8 minimum (ie: Java version 8)
I recommend AdoptOpenJDK as your Java installation source.

If you are using LibreOffice on Linux, then you are subject to bug 139538.
To work around the problem, please uninstall the packages:

If you still want to use the Embedded HsqlDB functionality provided by LibreOffice, then install the HsqlDBembeddedOOo extension.
OpenOffice and LibreOffice on Windows are not subject to this malfunction.


It seems important that the file was not renamed when it was downloaded. If necessary, rename it before installing it.

This extension was written in order to make usable in free software (LibreOffice or OpenOffice) your personal data (your address book) stored in your Android phone.

When the smtpMailerOOo extension is finally available, it will be the data source for mail merge by email, to your correspondents contained in your phone.

It will give you access to an information system that only larges companies are able, today, to implement.
