Write easy android applicaton for lotto machines

Lotto machines app It is an application that will send info to controller about lotto machines in shop. Brand owner will have more shops and more machines in every shop. There will be one phone in every shop that will be used for this app. After every shift, employees will send summary about money in those machines etc. Must work on android 4, stock cheap phones. - After an app is started, it waits for password - there are two passwds levels a) hardcoded admin password b) user password - after admin pass is typed, admin area will appear a) possibility to define name of shop (we have more shops, need to know what shop is writing us to) b) possibility to define codes of all lotto machines c) possibility to define users, each user has: a) name, b) password (login only using password, NO name required) d) possibility to edit phone number where summary sms is sent - admin must be of course able to delete / edit users, code of machines etc... - can't be typed only once ;-) - after user pass is typed, app is switched to user mode - name of logged user is somewhere displayed - user see several buttons a) donation / conduction / reward b) + / - of machines c) end shift d) previous shift button a) preview of previously added entries for donation or conduction or reward, it's some money X and info if it is donation or conduction or reward. User can click "Add" button and can add another entry. If it is much more easy, we do not need edit here, just add or delete previously added entries. So if "add" is clicked, user will fill amount of money and will chose if it was donation or conduction or reward. Please try to use radiobutton and not combobox - something that is easy on mobile to choose. button b) user will be able here to insert + or - that belongs to some machine. So he will see list of machines and after clicking desired machine he can view / enter new values for + and -. Every machine will have only one amount for + and one for - per shift. So no list of amounts, just + amount and - amount with possibility to rewrite? Update value? Up to you... button c) user will see full summary of shift, all donations, donductions, rewards typed (summarized), + and - values for all machines user will have two buttons here a) go back - to his menu where he can correct bad values b) end shift when he click on "end shift", all displayed summary is sent to sms to phone number that admin wrote into his admin area, then user is displayed info about sms successfully sent and user is logged out button d) - only a summary like in button c) but for previous shift (warning, we will need summaries for more previous shifts so prepare some good method for it ;-)) Common requirements - would you add sources to some private svn so that I can check it and build for client often? - could you finish it for tests in one week? - can you instruct me how and where to download tools for application testing? I do not have android :-) need software emulator - I require 100% source code, no obfuscation or other form of coding - strict real oop, no "one method" approach (use methods and not too much work with properties on objects etc.) - absolutely avoid copyblocks, so if you need to count something twice or more, make method for it! for example NEVER count price with VAT 2x, always use method!
