Android Code Snippet AdMob / b4a.example package name

Hi all.
I dont know if this is snippets, but anyway... ( maybe because i'm, today a few tired, i lost 30 minutes more or less for understand... yeaph i know...better that i rest )
If you try admob and your package name is: "b4a.example" Admob fail.
So you dont forget change name package ... magic magic B4A

It is one of the standard pitfalls!

i actually tried to upload my apk with the "b4a.example" and google send me a warning that that package name was already taken... it is not as logical as setting the keystore.
