This template includes base packages and files for the project. It also uses AndroidInjector(Dagger2) and MVP(basically it's not full MVP it is only View+Presenter).
You need to move folder BaseArch into your_android_studio_install_folder/plugins/android/lib/templates/activities
Then restart AndroidStudio (if it was launched) and create new project using BaseArch.
Activity and Fragment creation process should be using NewActivity and NewFragment.
