Could not find acceptable ICU library

[Ximena Shen]

Hello

I was connecting Android FireBird 5.0 (July 14th, 2025) with MAUI, however, it gives error of "Could not find acceptable ICU library".

I searched in the community, however,  it says it should be ICU 73.X match with FireBird 5.0. I'm confused because it is ICU 63.X when I downloaded FireBird 5.0 from official website.

Can you help about this case?

It depends on the OS. On Windows, it's indeed ICU 63, but on other OSes
it can be the OS-provided ICU library, which might be a different
version. I'm not sure about Android.

In any case, you need to rebuild the indexes, e.g. using `gfix -icu`, or
- if the Firebird .NET provider has it, the equivalent option in its API.

Android provides an unified ICU library with non-decorated names. Firebird
cannot use such versions because of a bug in INTL module.

Firebird has an Android build; I assume such issues are actually
addressed in such builds in some way.
