This session will provide a high level basic overview of the Android Application Framework, its Intent messaging facility, and how simple TextToSpeech can be implemented by using an Intent to find and make use of app resource already installed on the phone. It is a condensed version of a portion of the speaker's Introduction to Android Application Framework and APIs continuing education class for IEEE Boston Section. Code snippets from a demo app will be shown. We will touch on the life cycle of an Activity, which is one of the four core application components of the Android Application Framework, and see how widgets can be laid out and instantiated for an Activity's UI screen. We will see how an Intent object is used to activate certain operations, and how to take advantage of the intent mechanism to implement TextToSpeech. The demo app is taken from "Learning Android" by Marko Gargenta and published by O'Reilly.
