Thanks a lot, Mark.
I am trying to follow the advice in your previous mail.

^^^^^^^^^^^^^^^^^^^^
If you want to connect
an Android application to a database, you should write a rest service
(eg in Java) that talks to your database, and make your Android
application talk to that rest service. It will usually perform better,
and is easier to secure than direct database access.

I just released an artifact to Maven that contains the Firebird native
client (32 bit and 64 bit) for Windows and Linux.

Combined with Jaybird 3 or higher and JNA, this can be used to connect
using the native and local sub-protocols without having the Firebird
client on the library path.

Be aware, this solution does not work for the embedded protocol of
Jaybird. I plan to provide a similar artifact for embedded in the
future, but that is a bit more complicated to do.

See https://github.com/mrotteveel/jaybird-fbclient for details.
