Hi, sorry about my English, I'm using a translator.

Apparently I managed to solve the problem in my code. I was calling action.start() after another action.start().

I have a method that is called when it manages to read the barcode and sends this code to the api, as soon as this method is called I execute action.stop(), so as not to read the barcode more than once.
When this method finds the item of this barcode in the database, it returns the id and the UI routes to the details screen, when it doesn't find the item, the api returns an error message and the UI has to release the camera for a new query.

My error was calling action.start() at the end of this method even though it found the item and routed to the details screen, so when I went back to the reader screen and tried to read other code it gave this error message, basically because I was calling action.start() after another action.start().

What I did was to call action.start() at the end of the method only if it returned an error at the endpoint and the user had to read the code again.

Is that clear?
