Intergrate Android MQTT плагин AAR в Unity - Foregry Service [закрыто] ⇐ Android

[Anonymous]

Я пытаюсь запустить код в фоновом режиме на Android для проекта Unity. Поскольку Unity не разрешает фоновые службы напрямую, я создал библиотеку Android (AAR) и интегрировал ее в Unity. Он работает правильно. Androidmanifest.xml.
unity Integration: я экспортировал модуль как .AAR и положил его в активы/плагины/Android в свой проект Unity.
Проблем плагин. < /p>
Код и зависимости работают нормально в автономном приложении. Unity?plugins {
