Ошибка при запуске сканера штрих-кода zxing

0 голосов
/ 03 июля 2018

Я получаю эту ошибку при запуске кода сканера штрих-кода zxing. Это работало ранее, но после того, как я добавил некоторые другие действия (не относящиеся к операции со штрих-кодом), это действие не выполняется.

я получаю следующую ошибку. Любая помощь, почему это терпит неудачу, так как это работало, прежде чем я добавил больше действий? Я могу строить и компилировать без ошибок.
