Наблюдая за стеком, похоже, что ошибка происходит из-за инициализации firestore.

Ошибка начала всплыватьпосле недавних обновлений библиотек Firebase, не могу точно сказать, с какой из версий. Также приложение хорошо запускается в последних версиях Android.

Answer 1

Проблема заключалась в конфликте с библиотекой гуавы, согласно этому длинному сообщению на github .

Чтобы исправить это, мне нужно было изменить версию гуавы с '28 .0-jre 'на '28 .0-android ', вот так:

implementation group: 'com.google.guava', name: 'guava', version: '28.1-android'

Надежда может спасти кого-то несколько часов.
