/**
* This file demonstrates how to play simple sounds on both the RC and DS phones.
* It illustrates how to build sounds into your application as a resource.
* This technique is best suited for use with Android Studio since it assumes you will be creating a new application
*
* If you are using OnBotJava, please see the ConceptSoundsOnBotJava sample
*
* Use Android Studio to Copy this Class, and Paste it into your team's code folder with a new name.
* Remove or comment out the @Disabled line to add this opmode to the Driver Station OpMode list
*
* Operation:
*
* Gamepad X & B buttons are used to trigger sounds in this example, but any event can be used.
* Note: Time should be allowed for sounds to complete before playing other sounds.
*
* For sound files to be used as a compiled-in resource, they need to be located in a folder called "raw" under your "res" (resources) folder.
* You can create your own "raw" folder from scratch, or you can copy the one from the FtcRobotController module.
*
* Android Studio coders will ultimately need a folder in your path as follows:
* <project root>/TeamCode/src/main/res/raw
*
* Copy any .wav files you want to play into this folder.
* Make sure that your files ONLY use lower-case characters, and have no spaces or special characters other than underscore.
*
* The name you give your .wav files will become the resource ID for these sounds.
* eg: gold.wav becomes R.raw.gold
*
* If you wish to use the sounds provided for this sample, they are located in:
* <project root>/FtcRobotController/src/main/res/raw
* You can copy and paste the entire 'raw' folder using Android Studio.
*
