Using The Mac To Create A Podcast Or Video File (MP3)



In this video I create an audio file using Garageband. This can be a great tool for use with language labs because teachers can create their questions and leave a gap of time for students to respond. The program also enables MP3 files which are flexible for use with other programs.

I try to keep this tutorial simple with just a few simple steps to get started. Garageband also enables a range of great audio editing tools which can improve audio quality and volume. The clips can also be easily deleted, copied or pasted as needed.

Podcasts can be a great tool for bringing groups together collaboratively to make an audio project or to work with world languages. This tutorial was inspired by a question from Adriana Gonzalez at Andover High School who requested a way of creating audio files for the language lab which could have the space in time for students to respond. This provides a great way of taking ownership of the language lessons by creating their own content.

Section #3: Exporting the Application to a Device and Debugging it
Step 1.
This Google developer resource outlines some of the best practices for debugging code within Eclipse. Using Eclipse with the ADT plugin, you can access the built-in Java Debugger, along with DDMS, to perform the debug of your application.

Step 2.
Read: Debugging
This resource provides an overview for what to look for when debugging an application. This short article and resources outlines the main components that comprise a typical Android debugging environment. Use this resource as you review your application for exporting.

Step 3.
This resource provides suggestions for what to test for in the Android application. Use this as a starting point for choosing items to focus on in your application testing process. The guidance from this article will go a long way in making sure that your app runs seamlessly.

Step 4.
Complete Assignment #3: What are the critical components to look for when testing an application?

Section #4: Video Demonstration: Pulling it All Together

In this final video tutorial you will learn how to export the .APK file from the Eclipse software. You will then learn how to add an Android device to a computer and change its setting to that of an external device. You will be asked to download the “Astro File Manager” application to help you locate the .APK file on the device. At the conclusion of the video the .APK file will be transferred from the computer to the device and the “Astro File Manager” will be used to locate and run the application for testing on the Android device.

Step 1.
View & Practice: Lesson 9 [11:05]

SUMMARY
This lesson concludes the course in developing a mobile application using Java for Android. You have learned how to export the program that you have been creating as an .APK file which can run on a Android device and test the loading, user interface, counter, music, accelerometer and image swiper activities located within the menu of the application. In this course you have learned how to create an application which incorporates a launching graphic with sound that also includes a list menu of distinct items (counter, accelerometer, image swiper). The application you have learned to develop also has an icon that will appear on the apps page of an Android device.
