ntegración @zxing- error de cámara
Estoy trabajando en una aplicación de Android con integración de escáner de código de barras zxing. Es la vista previa de la cámara con un botón que inicia el escáner de código de barras. Usé este)
App funciona bien, pero solo el primer escaneo. Cuando quiero hacer otra exploración: error de cámara: captura de pantallaaqu
Cuando reinicio el teléfono, nuevamente solo funciona el primer escaneo.
¿Alguien puede ayudar por favor? Soy principiante. (Y perdón por mi inglés)
