Xcode User Default Reference
The Mac OS X user defaults system allows you to specify the values of program settings through your shell command editor instead of the program’s user interface (such as in the Preferences window). This facility allows program developers to give users access to features in early development or that may require particular knowledge to use properly. You use the defaults(1) command to access these settings. The Xcode application has several of these settings, which are also known as expert preferences or expert settings.

Xcode Debugging Guide (Tools & Languages: IDEs)
Finding and eliminating bugs in your code is a critical phase of the development process. Xcode provides advanced debugging facilities, which include debugging from the text editor so that you don’t stray far from your code, and using the mini debugger, which provides a graphical debugging experience that is less intrusive on the running application than other methods. You can also use a more traditional, specialized graphical debugger, or the debugger console.

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.
