Upgrade Android App

The existing app is used to capture some information (offline). The user selects an item from a list, selects a couple of radio buttons, adds a photo and gps coordinates. The app uses as input a .csv file. The output is also a .csv file with some additional fields (e.g. gps long lat) associated to existing records and the photo files.

The scope of this work is to perform minor updates to the application:

- add extra variables (i.e. add radio button)

- minor improvements to UI (mainly colors and font)

- add encryption/decryption of support .csv file. The algorithm used for encrypting and decrypting payroll files is a standard algorithm known as Advanced Encryption Standard (AES) (aka Rijndael)

Details/specifications are available and will be shared before commencement of the assignment.

Skills: Android, C# Programming, Java, Mobile App Development, Software Architecture
