[INFO PLEASE] - For my app

[alphanumericaracters]

I just need read PDF417 [Driver Licences] and QR [255 char] it´s for automate some work in my town.

I download the repo, make some changes and... Get it! an App that read only PDF417 and QR, only has 2 buttons. i Delete all the code and stuff's that don need.

But i have a problem reading PDF417 (Not me: The older one), the scan it's so fast, that sometimes doesn't read well, throw a string like: @W$&09&%%$88@#"#ON SM$#!@#N and must be: @0000987654321@JOHN SMITH@NN.

I know that is not a problem of the reader, but i want to know if i can merge 2 options, like: Type (PDF417) and time (8000), to gave them some time to put correctly the code in the camera.

And the other one is how to correctly call this app and get the result in other App. Ex: android.intent.action.MAIN and the extras needed for ex: PDF417 or QR bypassing the main window and getting the result of the scanning.

Cause we are using a DB that recibe the values from an Excel, and the "Other App" just send the values to the Excel (Im a VBA programmer with "Youtube" Android Java). The "Other App" i made it with App Inventor, but it has a module were i can use StartActivity, pass the Extras and get the value/response.

i just need info to get it done.
