Hello world android - creation with errors

Question

I'm trying to create my first app with Android but I've encountered some problems.

Following a tutorial and making: new android application -> blank activity

The default result should be:

enter image description here

With MainActivity.java and R.Java inside it.

But instead I've got this:

enter image description here

There are a lot of errors and the R.Java file is missing.

I can obtain a result similar to the tutorial one (with no errors), creating a new android application and unchecking create activity, but this time MainActivity.java under src is totally missing. Maybe I could copy the MainActivity.java of the first project and put into the second one, but I prefer understand why it doesn't work.

Thanks for the help. Best regards.
