openFileOutput does not create the file
<p>I used the following code to create a file:</p>

<pre><code>        FileOutputStream fos = app.openFileOutput(fileName, Context.MODE_WORLD_WRITEABLE);
        fos.write(content.getBytes());
        fos.close();
</code></pre>

<p>the file is create on the emulator but it is not created on my device (Samsung Galaxy Tab sdk 2.3).</p>

<p>There are no exception and no logs.</p>

<p>If I use getFilesDir I get a path that doe not exists. /data/data/it.xyz.xyz/files.</p>
