I've tried again, not by editing any of the .xml files manually, but selecting the MinSdkApi 14 and TargetSdkApi 19 in Module Wizard while creating a new project and it looks like it's working fine
Lately when I was editing the .xml files manually according to your instructions, I wasn't changing anything in Module Wizard while creating a new project (because you didn't tell me to), and that was in my opinion causing errors.
PS If my English is poor, sorry for that, I'm Polish.
