Hello,

No, I tested on Android 14, brltty works and is usable. You can install 
it from google play, so documentation is correct in this.

https://play.google.com/store/apps/details?id=org.a11y.brltty.android&hl=en_US

I played with brlapi in Android and at least older releases are usable 
with that simple tweak in build system which i mentioned.

My change causes, that libraries for all supported systems are generated 
without version suffix, which is not good, we need it only for  Android 
libraries, i Did it only to test whether it will work with correctly 
named libs.

With best

Peter
