Firebird 5.0 Android

[Piergiorgio Valli]

I should use Firebird for an application on Android with multithreading.

In the documention I read Local connections where I can use Classic and SuperClassic offer an “embedded”

https://firebirdsql.org/manual/qsg25-classic-or-super.html

With multithreading connection can I use a transaction for every  connection or there are limitation compare to an installation on Windows?

Usually on Android I use Sqlite but there very limitation with multithreading and transactions.

This could be big advantages compare to Sqlite an opportunite to Firebird.

Thanks

Regarding your subject, please be aware that Firebird 5.0 hasn't been
released yet. Questions specifically about Firebird 5.0 should be asked
on firebird-devel as long as it hasn't been released yet.

The embedded engine is exactly the same database engine as used in
Firebird server. You can have multiple connections and multiple
transactions from within the same application (and even multiple
applications if the servermode is configured appropriately, though I
don't think that is relevant for Android)

Even on Windows you must use separate connections if you want to use them
simultaneously from concurrent threads. Transactions are not enough.

Hi, thanks for quickly reply. 

I should build Qt with firebird support and Android. On Windows I have builded the driver for Firebird already.

I will send feedback after the test.

Thanks

Hi All,

I should use Qt 5.15.12 with Firebird, I have installed an vm with Ubuntu 20.04,

In the package Firebird-5.0.0.1306-0-android-arm64.tar.gz or Firebird-5.0.0.1306-0-android-arm64-withDebugSymbols.tar.gz there is not include folder with headers

Now I have used include folder of the package Firebird-5.0.0.1306-0-linux-arm64.tar.gz.

When I build the driver I need to specify the lib folder and include folder, Header files are the same?

What is the minimum ndk version  supported?

In WIndows when I use the library fbclient.dll I put all files (firebird.conf, firebird.msg etc) in the same folder of the library, on android it is the same?

Can I enable a log? Usually I use logcat to catch messages

Thanks
