I will follow the following Development protocol for your App :
Step 1: Based on the concept and scope, I build the design layout in photoshop and show you the draft for approval.
Step 2: After the Approval of the Design, I will convert it to an android UI 4.0 XML layout.
Step 3: After the XML layouts are approved , I start the development of the functional aspects of your app such as database, web services, functions...and I will keep you updated with the latest info and involve you in the beta testing stage.
Step 4: Once the development is done , I will check for risks and bugs and make sure that your apps work perfectly and its ready to launch
Step 5: After the final testing, your app will be submitted to Google App Store into your account.
