When I try to follow Embarcadero's tutorial for creating an Android app that connects to a Datasnap server with Delphi 12, I get this fatal error:
F2051 the unit data.sqlExpr was compiled with a different version of FreeAndNil
Could someone help?
Yes, the tutorial has worked for me in an older version (I don't remember which one). The Delphi installation is freshly tested on Windows 10 and 11, and Delphi can compile other kinds of projects for Android, and the described tutorial on Windows x64, but not the described tutorial for Android.
I tried reinstalling Delphi, changing the computer, uninstalling and installing a previous version of Delphi, checking for any updates, posting a case at Delphi, even with Delphi-Praxis forum. And now I am here.
