This simple app turns your Android phone into a Pre Saved Barcode Reader App.
To use this app the user just clicks the 'Pre Saved Barcode Reader' app icon and they are taken right into the app. The user is greeted by a button on the top of the screen labeled 'Select Saved Barcode'. Once clicked a pop up box from the bottom appears with several access options (Photos & Gallery) and permissions for the access (Just Once & Always). The user selects one of the access options then selects the permissions for this app. Afterwards they are taken to the next screen, which in this case is the 'Select a photo' screen. The user clicks the 'Download' area and they then select one of the downloaded Images.
