    <p>I'm having a problem where SoundPool crashes, but gives no programmatic indication that is has crashed. After it crashes, it will not play any more sounds until the application is reloaded (exiting via back button then restarting is not sufficient). LogCat gives me these error messages:</p> <pre><code>AudioFlinger: no more track names availlable [sic] AudioTrack: AudioFlinger could not create track, status: -12 SoundPool: Error creating AudioTrack </code></pre> <p>Yet, despite these errors, SoundPool.play() still returns a positive integer that increments for each new play request which, according to the documentation, indicates that there was not an error. Someone else started an Issue for this problem: <a href="http://code.google.com/p/android/issues/detail?id=13453" rel="nofollow">http://code.google.com/p/android/issues/detail?id=13453</a></p> <p>...however, there have been no responses. The code below is a minimalist Activity to consistently recreate this issue. Just create a new Android project, set the ID of the LinearLayout to main_bg, set the ID of the TextView to main_tv, and add a sound file named ding to res/raw. The sound file needs to be long enough to click on the screen four times before the first sound completes; mine is a 1.7-second 22050 Hz mono MP3 @ 96kbps. After a brief pause, the fifth click will generate the error messages above via LogCat. Or, you can just click a bunch of times until sounds stop playing.</p> <p>I have tested the error messages to occur on a T-Mobile G1 running Android 1.6, but they do not occur on a 1.6 emulator, a 2.1 emulator, or a 2.2 emulator.</p> <p>Does anyone know how to fix this problem, or is SoundPool just worthless for coincident sound effects on a G1?</p> <p>Code:</p> <pre><code>public class SoundTestActivity extends Activity implements OnClickListener { private SoundPool mSoundPool; private HashMap&lt;Integer, Integer&gt; mSoundPoolMap; private int index = 0; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); findViewById(R.id.main_bg).setOnClickListener((OnClickListener)this); initSounds(); mSoundPoolMap.put(index, mSoundPool.load(getApplicationContext(), R.raw.ding, 1)); } public void initSounds() { mSoundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0); mSoundPoolMap = new HashMap&lt;Integer, Integer&gt;(); } @Override public void onClick(View v) { int result = mSoundPool.play(mSoundPoolMap.get(index), 0.99f, 0.99f, 1, 0, 1f); ((TextView)findViewById(R.id.main_tv)).setText(Integer.toString(result)); } } </code></pre>

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.
