    text
    copied!<p>I'm receiving a <code>null</code> reference when I try to play a sound through my Android chat app. Every time a smile appears in the protocol string, I want to play an audio sound. My sound files are in OGG format and are located in <code>res-&gt;raw-&gt;mysound.ogg</code>.</p> <p>I have the following <code>SoundManager</code> class in my Android class:</p> <pre><code>package chatclient.utility; import java.util.HashMap; import android.content.Context; import android.media.AudioManager; import android.media.SoundPool; public class SoundManager { private SoundPool mSoundPool; private HashMap&lt;Integer, Integer&gt; mSoundPoolMap; private AudioManager mAudioManager; private Context mContext; public SoundManager() { } public void initSounds(Context theContext) { mContext = theContext; mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); mSoundPoolMap = new HashMap&lt;Integer, Integer&gt;(); mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE); } public void addSound(int Index,int SoundID) { mSoundPoolMap.put(1, mSoundPool.load(mContext, SoundID, 1)); } public void playSound(int index) { int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); } public void playLoopedSound(int index) { int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f); } </code></pre> <p>}</p> <p>And here is my code in my main class to call it:</p> <p>In my <code>onCreate</code>:</p> <pre><code> mSoundManager = new chatclient.utility.SoundManager(); mSoundManager.initSounds(getBaseContext()); mSoundManager.addSound(1, R.raw.bigsmilesmiley ); //:D mSoundManager.addSound(2, R.raw.smilesmiley ); //:) mSoundManager.addSound(3, R.raw.tonguesmiley ); //:P mSoundManager.addSound(4, R.raw.confusedsmiley ); //:S mSoundManager.addSound(5, R.raw.ofacesmiley ); //:O mSoundManager.addSound(6, R.raw.sadsmiley); //:( </code></pre> <p>And then to call it:</p> <pre><code>if (pollServerResult.contains(":)")) { mSoundManager.playSound(2); } else if (pollServerResult.contains(":D)")) { mSoundManager.playSound(1); } else if (pollServerResult.contains(":P")) { mSoundManager.playSound(3); } else if (pollServerResult.contains(":S")) { mSoundManager.playSound(4); } else if (pollServerResult.contains(":O")) { mSoundManager.playSound(5); } else if (pollServerResult.contains(":(")) { mSoundManager.playSound(6); } </code></pre> <p>The only problem is I get a <code>null</code> reference when someone posts one of these faces.</p>
