Body
This code used to work. Then, maybe I changed something, somewhere (or if I know Android right, an update introduced a bug in the media player). It stopped working on some devices! Especially my Nexus S (2.3.6). The file <code>test.m4a</code> (17 775 201 bytes) was downloaded by the app. To verify its integrity, I copied it to the SD and played it on my PC. No problem! Also binary-compared it with the original file, and it matched 100%. <pre><code>try { _mediaPlayer = new MediaPlayer(); _mediaPlayer.setOnCompletionListener(this); _mediaPlayer.setOnPreparedListener(this); _mediaPlayer.setOnSeekCompleteListener(this); _mediaPlayer.setOnBufferingUpdateListener(this); _mediaPlayer.setOnInfoListener(this); _mediaPlayer.setOnErrorListener(this); // I even tried reading the file from SD card. Same error... File file = new File("/data/data/com.mycompany.myapp/files/MediaCache/Test.m4a"); // file.isFile() == true // file.length() == expected value! FileInputStream is = new FileInputStream(file); _mediaPlayer.setDataSource(is.getFD()); // Throws! // If I use the filename as parameter, it throws later when preparing the media player... _mediaPlayer.prepareAsync(); } catch (Exception e) { // java.io.IOException: setDataSourceFD failed.: status=0x80000000 e.printStackTrace(); } </code></pre> Q: What might cause this <code>IOException</code> for <code>setDataSourceFD</code> when the file is indeed valid? UPDATE: Here's a 98 kB audio file that I cannot play on my Nexus S (2.3.6): <a href="http://www.2shared.com/audio/wUKoRiQk/test.html" rel="noreferrer">http://www.2shared.com/audio/wUKoRiQk/test.html</a> A friend of mine runs some ZTE device (2.2) and it seems to work. I don't get it!

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.
