8. AS vs IntelliJ IDEA
Android Studio ≈ IntelliJ IDEA
● IDEA поддерживает различные системы сборки
● IDEA использует устаревшие шаблоны при создании проекта
(старая версия gradle-plugin, Fragment - вложенный класс в
Activity)
● IDEA не содержит Android Project View
● IDEA не позволяет проверять обновления Android SDK
