Does using web views in apps have a negative impact on accessibility features such as Android's TalkBack or font size settings? Or iOS' VoiceOver feature?

I have seen many tools or browser plugins available for web accessibility testing. But how do people check accessibility for android apps?
Available options:
1- use accessibility Scanner
2- enable A11y checks for your UI espresso testing
AccessibilityChecks.enable()
3- use talkback to manually verify your app behavior.
we are developing app in asp.net HTML5 css3 for Iphone and Ipad. Its database driven web app. I want to know what are the best pracices to access DB from Mobile client. What are the database security considerations? What are the security risks that I should consider whaile developing such app that will run on mobile.
Since you're developing in asp.net, which is a web framework, the same security considerations should be made as a normal web application.
As it's a web application, mobile or desktop isn't relevant.
Microsoft have a a great website covering Security Considerations for ASP.NET Web Applications, I would suggest you give this a good look over and implement these into any websites you build.
The only things you need to consider whilst building a mobile website is responsive design, and restrictions on the browser.
Responsive Design:

Browser Restrictions
For browser restrictions you will have to look around but for example up to iOS 5.x.x you couldn't upload using an input tag, and obviously in iOS you won't be able to download unsupported file types to the device.
Accessing from Client
As with any application where a client is accessing a database with other client data in it, input sanitation is a must.
E.g a link to change a document is like Document.aspx?ID=4
Don't assume that the user wouldn't change the ID in the URL just to see what happens, always do checks for everything the user attempts.
I have an existing website done in asp.net webforms .net V4. Visual studio 2010
I want to add a simple mobile section to the site for low end feature phones.
Where do I start?
Do I just do a redirect on detection of a mobile device, and jump to a page with a VERY simple UI? or must I use a special framework for it to render correctly? Should I be using a WAP site?
Note that this is for very low end phones
Either you can redirect the user on detecting that he is using a mobile device or make some thing entirely new using phone gap or something.
Since mvc4 mobile is still new and has limited info on it at the time, I was wondering if this mobile framework is meant for windows phone applications or is meant for mobile web browsers in general. In other words if i create a mvc4 mobile application, would it be compatible to use with all mobile browsers? Thanks for any info.
It is meant for mobile web browsers in general. More information and a list of how to test different browsers is located at http://www.asp.net/mvc/tutorials/mvc-4/aspnet-mvc-4-mobile-features.
I need to build a web application in asp.net where users can use their scanner to upload images to the website. Is there a flash or a silverlight component out there that can accomplish this?
Flash or Silverlight might not a good choice. You may use an ActiveX (in IE) or an NPAPI plugin (Chrome, Firefox, etc.) to get access to the scanner via the TWAIN API.
If you have the time or a limited budget, you can create your own plugin. Otherwise, you can try a commercial TWAIN library. Dynamsoft has a multi-browser web-scanning toolkit which supports scanning and uploading images in all mainstream browsers/
