Write an Android application with a web site that can customise the layout and the forms -- 2

Dear Developers I need to create a mobile app in which a manager can create many assessments and customise the forms of each assessment thru a website. The system should be similar to some survey apps out there that allows you to customise and test the surveys thru a website and sync with your app. The assessment contains questions, data entry from the user (Eg, Name and membership number), information screens and the ability to sign at the end. Each question varies by its type, Example: Multi-Select, Single-Select (Radio boxes) that must be available for the user to choose and add to the forms. These assessments must be synced with a backend server and must be able to run offline. Once connected to a wi-fi hotspot or 3g, the app must upload its results to the backend server. These results should be stored in a databases (preferably mySQL) and can be later exported to csv and spss format. The manager should also be able to view the results in various types of graphs. The user of the mobile app must be able to switch between assessments and continue from where they left off even if the app was closed. A side menu should show submitted and incomplete assessments and assessments that have not been uploaded to the server. I am open to cross-platforms. Please let me know if you require any more info.
