There is a need to make a read operation on the DB sqlite file. There's a explanation of how it should work in following application. Application works itself and all you had to do is code a module to search and read in database item that has specific code (barcode). In simplier words, when you scan a barcode that already is in database it should display all properties in editexts (productname, productquantity, productcode). If barcode of item doesn't exist in database it shouldn't show any information just blank space to possibly initialize new item in database. (which is already programmed as default).
All further information including project file, application navigation, etc. will be provided in private message after negotiation talk.
There is second option more paid - information should be read from XML file into DB sqlite file and then the same action as above. (more explained if interested in PM)
