List assets in a subdirectory using AssetManager.list
<p>My application has an assets directory in which I've dumped a bunch of text files I need to load at runtime.</p>

<p>I have a directory full of assets of a particular type (i.e., "assets/subdir") and I want to load all of the files in this directory, one at a time.</p>

<p>I have code like this:</p>

<pre><code>
AssetManager assetMgr = getAssets();

String[] assetsIWant = assetMgr.list("subdir");

for(String asset: assetsIWant) {
  doAssetyThing(asset);
}
</code></pre>

<p>I've tried a zillion different versions of the parameter to assetMgr.list() and am not getting anywhere.</p>

<p>If I use "/", I get back a list containing the "assets" directory, and a few random other items (META_INF, for example).  If I pass any other string (like "assets" or "assets/" or "/assets" or "/assets/" or "mysubdir" or "/mysubdir" or "assets/mysubdir" or ...) then I get back an empty array.</p>

<p>The documentation is unfortunately fairly incoherent.</p>

<p>Does anybody know what the correct formula for that list() parameter is?  </p>
