Хотя я смог создать свое приложение с CRNA и извлечь его с помощью npm run eject, и запустить его с помощью npm run android, через три недели это произошло.За последние 20 часов я удалил узел, android studio, android sdk и снова загрузил их все.Все еще такие же ошибки происходят.Я совершенно не понимаю, если это происходит из-за gradle или java или android.У меня два вопроса.
Вопросы
1.Как я могу решить эту проблему?
2.
a) crna myApp -> cd myApp -> npm run eject -> npm run android |
б) реактивный нативный init myApp -> cd myApp -> реактивный нативный run-android
Второй работает хорошо, но я не люблю expo.Кажется, он компилируется и работает медленнее и создает много ошибок с помощью ссылки «родной».Я хочу знать, при каких обстоятельствах я должен использовать один из них в связи с этим.Я собираюсь убить себя, поэтому любая помощь будет оценена с лучшей стороны.
