Совместимость с Android 5.0 Lollipop

Question

Совместимость с Android 5.0 Lollipop

Рейтинг: 1Ответов: 1Опубликовано: 17.11.2014

Я некоторое время пишу приложение на Android, и вчера попытался запустить его на Nexus 5 Android 5.0. При запуске выдаёт ошибку. На Android 4.4 работало исправно. Приложение представляет из себя два потока, один из которых ежесекундно обновляет 2 собственных View-объекта, а второй — выполняет некоторый бесконечный цикл. Что могло послужить причиной того, что приложение не запускается на Android 5.0 Lollipop? Какие существуют методы обеспечения совместимости с Android 5.0 Lollipop?

Вот логи:
