Jaybird cannot be used on Android as Jaybird uses classes from the Java
runtime which are not available on Android (although Android uses the
Java language and offers parts of the Java runtime, it is not a complete
Java implementation). For a while there was a fork of Jaybird for
Android, but as I recall the maintainer of that version stopped around
Jaybird 2.2.4.

For security and performance reasons, you shouldn't connect directly to
a database from Android anyway, but instead use a REST API (e.g. written
with Spring Boot) to mediate between your application and the database.

Hi Mark.

Can you please elaborate on this issue.
How can Spring boot connect directly when JDBC can't?

Merry Christmas.

I'm not proposing to use Spring Boot on Android. The problem is that
Jaybird doesn't work on Android (and that IMHO, connecting directly to a
DB from Android is a bad idea in general). The solution is then to write
a REST service, for example using Spring Boot. Then the Android
application uses HTTP/REST to talk to the REST service, and that REST
service talks to the database.

There is an Android build of Firebird. I wonder what the use case of it is if one should not connect directly to it.
I'm asking because we are contemplating about a Android POS software with Firebird.

Br,

That is for running Firebird directly on your Android, and then most
likely as an embedded database engine. That is different then
establishing a connection to a remote Firebird server.

However, the case remains that Jaybird, out of the box, will not work on
Android.

Hello. Did you manage to write a REST server that takes data from the database and returns the client to the android? is there any example?
