blocks|key|1065431|text|你的例子基本上就是我正在使用的。然而，它永远不会在仿真器上工作，因为仿真器默认没有任何铃声，并且content://settings/system/ringtone不能解析为任何可播放的内容。它在我的实际手机上运行良好。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1065432|entityMap^0|1C|Y|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Your example is basically what I'm using. It never works on the emulator, however, because the emulator doesn't have any ringtones by default, and <code>content://settings/system/ringtone</code> doesn't resolve to anything playable. It works fine on my actual phone.

You can push a MP3 file in your /sdcard folder using DDMS, restart the emulator, then open the Media application, browse to your MP3 file, long press on it and select "Use as phone ringtone".

blocks|key|1065501|text|将音频文件复制到模拟器的SD卡并通过媒体播放器选择它作为默认铃声确实解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1065502|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Copying an audio file to the sd card of the emulator and selecting it via media player as the default ringtone does indeed solve the problem.

If a user has never set an alarm on their phone, the TYPE_ALARM can return null. You can account for this with:

<pre><code>Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

if(alert == null){
 // alert is null, using backup
 alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

 // I can't see this ever being null (as always have a default notification)
 // but just incase
 if(alert == null) { 
 // alert backup is null, using 2nd backup
 alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE); 
 }
}
</code></pre>

You can simply play a setted ringtone with this:

This works fine:

 thePlayer.setVolume((float) (audioManager.getStreamVolume(AudioManager.STREAM_NOTIFICATION) / 7.0)),

This is the way I've done:

<pre><code>Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
MediaPlayer mp = MediaPlayer.create(getApplicationContext(), notification);
mp.start();
</code></pre>

It is similar to markov00's way, but uses MediaPlayer instead of Ringtone which prevents interrupting other sounds, like music, that might already be playing in the background.

I have been looking everywhere how to play a ringtone/alarm sound in Android. 

I press a button and I want to play a ringtone/alarm sound. I could not find an easy, straightforward sample. Yes, I already looked at Alarm clock source code... but it is not straightforward and I cannot compile it.

I cannot make this work:

<pre><code>Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); 
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(this, alert);
final AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
 player.setAudioStreamType(AudioManager.STREAM_ALARM);
 player.setLooping(true);
 player.prepare();
 player.start();
}
</code></pre>

I get this error:

<pre><code>04-11 17:15:27.638: ERROR/MediaPlayerService(30): Couldn't open fd for
content://settings/system/ringtone
</code></pre>

So.. please if somebody knows how to play a default ringtone/alarm let me know. 

I prefer not to upload any file. Just play a default ringtone.
