даю приложение, подобное Uber, но у меня возникла проблема после внезапной ошибки и сбоя приложения. Я перепробовал много способов, чтобы справиться с этой ошибкой, но она не сработала. Все ответы на похожие вопросы, которые я мог найти в Stackoverflow, были о том, что эта проблема вызванаFirebaseDatabase.getInstance().setPersistenceEnabled(true) и мне пришлось удалить этот код строки, так как это ошибка в Firebase, которая еще не решена. Но это не решило мою проблему, так как у меня не было такого кода. Вот почему я подумал, что это вопрос, который не относится к stackoverflow, и задал вопрос. Это мой код Java
