Я пытался загрузить изображения во время выполнения в библиотеку изображений из множества ссылок на изображения для моего AR проекта. Во время тестирования приведенного ниже кода мое приложение android зависало со следующими ошибками

Первоначально загружается несколько изображений и добавляется в библиотеку, и происходит сбой. Это потому, что загруженные изображения имеют большой размер? Я попытался освободить размер с помощью метода удаления данных обработчика веб-запросов, но безрезультатно. Как решить проблемы с памятью. Есть рекомендации?
