Android Question SOLVED Try to update an old APP from B4A 7 to new 8.80

[tigrot]

Hi everybody,
I have loaded B4A 8.80, my old program refuse to compile and the errors are:

B4A Versione: 8.80

*** Legacy debugger is deprecated. ***
 It is recommended to switch to the default debugger (Tools - IDE Options).

I have no idea where is the error, since no endX is coded in my app. Maybe a library?
Can someone give some hint to me?

Happy New Year.

- Use the _B4A SDK MAnager, download all recommended items (or updates)
- Configure your IDE to use Android.jar from SDK 28 (Tools-Configure Paths)
