    <p>I am trying to implement background music into an Android game that I am working on. When the game gets to the activity that the music is in, the music starts and continues to play just fine. However, the music stops when one of my custom view objects is dragged as part of the game. I then tried putting the mediaplayer into a thread, but it worked exactly the same. What do you think?</p> <pre><code>if(Theme.getMusic()!=0){ //Theme.getMusic() returns a different resource depending on other settings. MediaPlayer mp = MediaPlayer.create(GameView.this, Theme.getMusic()); mp.setLooping(true); mp.start(); } </code></pre> <p>Logcat says this (last 6 lines seem relevant, not sure what to make of them):</p> <pre><code>04-19 18:13:54.440: INFO/MediaPlayer(10427): MediaPlayer create(context,resid) 04-19 18:13:54.440: INFO/MediaPlayer(10427): MediaPlayer 04-19 18:13:54.450: DEBUG/MediaPlayer(10427): hasHDMIPermission: -1 04-19 18:13:54.450: DEBUG/MediaPlayer(10427): registerHDMINotification 04-19 18:13:54.450: INFO/global(10427): Default buffer size used in BufferedReader constructor.

This, for some reason, has fixed my problem! Although, I would still like to know what my problem was in the first place. Here's what I have now:</p> <pre><code>MediaPlayer mp; ... mp = MediaPlayer.create(GameView.this, Theme.getMusic()); ... </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.
