Я впервые играю с Android и Bluetooth.Итак, я попробовал пример BluetoothChat на android.com, но у меня были некоторые проблемы.
Вот вывод LogCat:

Остальные файлы тоже оригинальны.Надеюсь, ты сможешь мне помочь.Я не мог импортировать оригинальные файлы, поэтому я создал новый, заменив каталоги и файл mainfest.Может быть, есть проблема.
