Android Developer for a Very Simple App - repost

We want to develop an Android application (up-to 6-7 screens only) . Basic functionalities we are looking at: 1) Load detail from a WCF service ( WCF service is done and running fine) 2) Store WCF returned object in an isolated storage (app data) 3) Load the information and display on screen 4) Add a reminder on phone 5) Basic form submission 6) very basic map integration ( Lat / long would be supplied by WCF and you have to show a pin on the map , show directions ( pull from google directions api ) ) That's all. What is already done: 1) App design (photoshop) 2) Equivalent app in Windows Phone is already done 3) WCF Time: 1 week
