As soon as I create a new project in Android Studio, I get 2 errors. When I add the line “ package="com.example.creation_codes" ”, the error in the line “android:label=”creation_codes“” disappears. But why do I have to add this line manually, shouldn't it be automatic when I create the project?

then when I create a github repository and upload the project, the number of errors increases and I don't know what these errors mean.
