Programming with Google Android and Eclipse
Android is an operating system based on Linux with a Java programming interface. It provides tools, e.g. a compiler, debugger and a device emulator as well as its own Java Virtual machine (Dalvik).
Android is created by the Open Handset Alliance which is lead by Google.
Android uses a special Java virtual machine (Dalvik) which is based on the Apache Harmony Java implementation. Dalvik uses a special Bytecode so that you have to use the Android compiler to create this special byte-code.
Android supports 2-D and 3-D graphics using the OpenGL libraries and supports data storage in a SQLLite database.
For development Google provides the Android Development Tools (ADT) for Eclipse to develop Android applications.

iPhone Application Tutorial
Delegation is a pattern where one object periodically sends messages to another object specified as its delegate to ask for input or to notify the delegate that an event is occurring. You use it as an alternative to class inheritance for extending the functionality of reusable objects. In this application, the application object tells its delegate that the main start-up routines have finished and that the custom configuration can begin. For this application, you want the delegate to create an instance of a controller to set up and manage the view. In addition, the text field will tell its delegate (which in this case will be the same controller) when the user has tapped Return.
