Android app

Dear freelancer, We need a basic app to use on an android phone or tablet to take pictures of incoming parcels and that is able to scan a barcode. The app is only for our own specific use and will not be distributed via an Appstore. 1st step - Scanning barcode The first step, and input for the file names of the pictures, is done by scanning a barcode (not QR). The scan field needs to be demarcated since barcodes can be close to each other and we need to scan the right one. 2nd step - Pictures Direct after scanning the barcode we take several pictures at close range (0,5 to 1,5 meter of the parcel). All pictures taken need to get the filename from the barcode followed by an indent and index number to make the file name unique (e.g: -01,-02,-03 etc). In the app itself needs to be an option to switch the flash on/off as a default setting. 3rd step - Storage On screen is a 'store' button. Pressing this will upload the pictures to a predefined dropbox folder. Pictures need to compressed to max 150k. At the moment we use Whatsapp to take the pictures. Their compression suits our needs. After the store button is pressed a new barcode can be scanned in step one for the following series of pictures of a new parcel. Interested? Reply now!
