75.3 About the Example Project
The remainder of this chapter will work through the creation of an example application intended to demonstrate the use of the MediaPlayer and MediaRecorder classes to implement the recording and playback of audio on an Android device.
When developing applications that make use of specific hardware features, the microphone being a case in point, it is important to check the availability of the feature before attempting to access it in the application code. The application created in this chapter will, therefore, also include code to detect the presence of a microphone on the device.
Once completed, this application will provide a very simple interface intended to allow the user to record and playback audio. The recorded audio will need to be stored within an audio file on the device. That being the case, this tutorial will also briefly explore the mechanism for using SD Card storage.
