Я создал приложение для потоковой передачи видео с использованием Javafxports. Приложение работает на моем мобильном устройстве huwaei p-smart Android 8, но не может подключиться и загрузить на Android 6 (вкладка Lenovo 10 "). Приложению необходимо обнаружить модуль управления, подключиться к нему и получить данные, определенные в классе FSGuiCommunications (ниже ).

Из logcat я заметил, что управление не перешло в блок startservers () или даже не получило пакет. Связано ли предупреждение с Android 4.1 в logcat с блокировкой потоков? Я не наблюдал такого поведения на своем мобильном устройстве Android 8.
