Как исправить FATAL EXCEPTION: main android.os.NetworkOnMainThreadException

Извините, если это неправильный английский, потому что я использую переводчик.

Я скачал программу с github, которая может управлять мышью на телефоне Android. Нет проблем с подключением к серверу, но возникает ошибка при касании текстового поля для управления мышью.

Уникально, что при запуске программы с виртуальным устройством ошибки не возникает и работает хорошо.

Я видел много примеров и ответов, но не могу их решить, поэтому публикую повторно. ;_; Я был бы очень признателен, если бы вы могли сказать мне, какие части изменить.
