На Android мне внезапно не удалось заставить работать сервер Metro Bundle. Я отлаживал это в течение последних 5 часов и не смог найти причину этой проблемы. В отличие от этой проблемы, мое приложение даже не начинает показывать LogBox предупреждение о красной ошибке. Просто сразу вылетает.
Всякий раз, когда я пытаюсь запустить приложение для Android (я пробовал со всевозможными настройками, включение/отключение Hermes, разделение ABI, явное принудительное использование версии SoLoader, удаление всех видов кода, чтобы получить минимальное приложение, очистку кеша gradle, добавление android:usesCleartextTraffic="true" к моему AndroidManifest.xml и т. д.), приложение запускается с белым экраном и сразу после этого вылетает. Мне удалось найти некоторые исключения в Logcat:

Когда я вручную создаю пакет JS, используя следующую команду:
npx react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
Мне удалось успешно запустить приложение через Android Studio, но, конечно, это не решение, так как мне приходится запускать эту команду каждый раз, когда я что-то меняю (даже в JS), поэтому у меня больше нет live-reload, я у меня нет console.log, и у меня ужасный опыт разработки.
Итак, вкратце: каким-то образом мое приложение больше не может передавать пакет через сервер сборщика метро на localhost, но он работает, когда я вручную создаю пакет. Он даже не запускает Metro Bundler! На iOS работает.
