My package name was previously "HBVerbrauchszaehler", in B4A V1.8 package name must are written in lower case. If I then change my existing APP is not overwritten, and produces twice, there is error message "The application has unexpectedly quit."
What can I do? Is there a way to re-use the package name with capital letters?
Package names by convention should be lower cased. There was actually a bug in previous versions regarding non-lower case package names.
You will need to use lower case name.
The problem will be that the directory exists "HBVerbrauchszaehler" already with capital letters and will try the same directory "hbverbrauchszaehler" create small letters, which is probably not possible.
The directory in small letters was not created, but a program icon.
After that, I'm the object directory \ \ HBVerrbauchszaehler now in hbverbrauchszaehler
have changed, the app is running again and overwrites the previous APP and retains the data.
Problem now is that only now are in the application window icons exist two APP,
which both start the same app.
