    "# Exercise: Shooting Game with Sound\n",
    "---\n",
    "## Objectives\n",
    "\n",
    "In this exercise you will learn about generating short bursts of sound within your app with minimal latency. We will leverage the SoundPool class for this purpose. At the end of this exercise you will be able to:\n",
    "\n",
    "* Use the SoundPool class to include short bursts of sound to be generated on the fly within your app\n",
    "* Trigger the sound based on the occurrence of an event in your app\n",
    "\n",
    "## Introduction\n",
    "\n",
    "This project demonstrates the use of the SoundPool class to generate various sounds within your game. When the AndroidGuy is hit by a bullet, we show an explosion image on the screen. Accompanying this image, we now generate an explosion sound in this exercise.\n",
    "\n",
    "## Textual Instructions\n",
    "---\n",
    "### Step 1: Examining the Project Files\n",
    "\n",
    "1. Download the [ShootingGameSound.zip](http://w02.hkvu.hk/edX/COMP107x/w4/ShootingGameSound.zip) file, unzip it and import the project into Android Studio.\n",
    "2. Open the **SoundEffects.java** file.\n",
    "3. Open the **ShootingGame.java** and the **DrawView.java** files and update them as explained below.\n",
    "\n",
    "---\n",
    "### Step 2: Updating the ShootingGame Activity\n",
    "\n",
    "1. Replace the // TODO comment in the **ShootingGame.java** file with the following code.\n",
    "\n",
    "        SoundEffects.INSTANCE.setContext(this);\n",
    "\n",
    "---\n",
    "### Step 3: Updating DrawView Class\n",
    "\n",
    "1. Replace the // TODO comment in the DrawView.java file with the following code.\n",
    "\n",
    "        SoundEffects.INSTANCE.playSound(SoundEffects.SOUND_EXPLOSION);\n",
    "\n",
    "2. Run the app and see the result."
