Development Tools (ADT) bundle that includes the Eclipse Integrated Development Environment (IDE), Android development tools, Android SDK tools, Android platform tools, the latest Android SDK, and an emulator. The ADT bundle is for Windows only. If you are going to develop on the Mac, you will have to download Eclipse separately and use the preceding URL to get the various other tools. If you have an existing Eclipse installation, you can use this location to add the Android tools. Appendix A,
DialogFragment) displays the dialog. The method requires an instance of a FragmentManager and a name, which the FragmentManager uses to keep track of the dialog. Be sure to call the initChangeDateButton() method in the onCreate method of ContactActivity. The app interface is ready to be tested! Run it to be sure that the dialog is displayed and the correct date is placed in the TextView. Summary Creating layouts is a lot of work! In this chapter you learned how to use Eclipse to create an

The focus up must be before the clear focus. Otherwise it will override the clear, and autofocus will again

Place the contact ID in the bundle that is passed to the ContactActivity. The method putExtra(key, value) is used to put primitive data types in the Intent so that they are accessible by the activity receiving the intent. Save all your changes and test the adapter on the emulator. If you have properly coded these objects, your ContactListActivity in the emulator
