Qt5 & Android, вопросы начинающего Опции

[Majestio]

Доброго времени суток!

Наконец-таки дошли руки достроить свою среду разработки с Qt 5.4.0 для возможности создания приложений для устройств, работающих под управлением Android. Возникли неочевидные для меня вопросы, прошу ответить хотя бы в двух словах, или ткнуть в правильный линк инета:

1) Собрал тестовую программку, загрузил ее в эмулятор, ну как бы все заработало ...



Как это загружается в эмулятор, я пока не знаю, да и не важно. Вопрос в другом - глянул в каталог сборки и немного снесло крышу.
Не понимаю, что является результатом? Что и как нужно будет загружать в реальное устройство?

Листинг содержимого каталога сборки таков:

2) Выбирая Qt/C++, я всячески старался избегать Java. Знания чисто концептуальные по ней, практики нет, да и не особо пока хочется. Но ... о5 же в каталоге сборки я обнаружил какие-то созданные джавовские классы. Каким боком они тут? Создается впечатление, что они - некая прослойка между созданным мною приложением и системой. Так ли это? А можно без них - если да, то как?
