Mobile App not scanning bar codes properly - app keeps closing

Hi,

I am testing out the Service Desk Plus scanning function for our IT assets by using my Sony phone.  I have installed SDP on my mobile and have been trying to scan the bar codes.  The bar code details appear but when i go to add it on SDP after i click the tick box, it keeps closing and says "ServiceDesk Plus has stopped".  I can either Open the app again or send feedback.  Why wont it let me add the rest of the asset details?  I can see the next page but then it closes on me and then i have to start again.
Is this function only compatible with some phones?  I have a SONY Xperia L1
