Android Widget Development Guide with examples
Native vs Cross platform development. A quick comparison
Here are some findings about app development courses.
Mono
There are few well managed mature software’s like Monotouch for iOS and Monodroid for android, Appaccelarator, Marmalade( http://www.madewithmarmalade.com ) to develop apps using code reuse strategy and could get some useful benefits like
- Business logic code, using the base class libraries
- Use of existing UI-less .NET components
- Use of libraries
- Common device code (ftp, zip unzip libraries, Wi-Fi, network communication, Bluetooth, database and web service that we may need in the future)
- Separate layers of UI and Business logic
Mono has all stated above with in few clicks and line of code. Here are some references http://docs.xamarin.com/ios/guides/advanced_topics/assemblies
