Android Question [SOLVED] unspecified 7.80 compilation error

[Star-Dust]

I started recompiling my Apps that were developed with 6.5 with the new version 7.80. Here is the first mistake of my first compilation ... What error would it be?

B4A Versione: 7.80
Analisi del Codice. (0.22s)
Compilazione del codice. (0.37s)

File ObsucastorMap.txt creato nella cartella Objects.
Compilazione del codice di layouts (0.09s)
Organizzazione Librerie. (0.00s)
Generazione file R. Error

Now the same mistake gives me also 6.50
yesterday I added sdk 24,25,26 that I did not .. can this be what generates an error?

P.S. I created an empty project and compiled it without errors.

Are you using the latest Android SDK installed with B4A Sdk Manager?

Try to add the libraries from your project to a new project and see whether the error occurs.

The problem library is FirebaseAdmob. Very strange.
Now I have removed and it signals another error, but at least I know which one

I solved, I had to insert the JSON file in the App folder.

With older versions of SDK, I was not asking for it, updating the SDK required the json file.
