    <p>I have a class called Sound.java that consists of 3 functions (initSound, addSound, and playSound).</p> <pre><code>public static void initSound(Context con) { mContext = con; soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); soundPoolMap = new HashMap&lt;Integer, Integer&gt;(); audioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE); streamVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); streamVolume = streamVolume / audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC); } public static void addSound(int index, int SoundID) { soundPoolMap.put(index, soundPool.load(mContext, SoundID, 1)); } public static void playSound(int index) { soundPool.play(soundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f); } </code></pre> <p>I called the initSound and addSound in the MainGame.java constructor. </p> <pre><code>Sound.initSound(getContext()); Sound.addSound(1, R.raw.machine_gun); </code></pre> <p>and called playSound inside a Thread (looping) in MainGame.java. PlaySound called every second when an event is triggered (for example, when an enemy is in sight, troops (more than one) will shoot (play the sound) continuously until the enemy is dead).</p> <pre><code>Sound.playSound(1); </code></pre> <p>The problem is when the sound plays, the app is slowing down. I'm using soundpool because as far as I know for sound effects, soundpool is better than mediaplayer. (I've tried mediaplayer and the lag is even more.)</p> <p>The sound file that I use is .wav (unsigned 8bit PCM, 1 Channel, 8000hz) with size 5.44KB.</p> <p>Is there a better way to play effect sounds without slowing the game performance, or is mine wrong? I really appreciate any ideas and responses.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
