copied!<p>Figured out a work-around, in setting the default ringtone.</p> <p>For the people who uses both a <code>RingtonePreference</code> and <code>PreferenceManager.setDefaultValues()</code>, <code>android:defaultValue</code> on a <code>RingtonePreference</code> takes in a string to a ringtone's URI. By providing an empty string, you're defaulting the preference to "silence," while other strings will probably lead to no valid URI.</p> <p>The work-around, then, is to provide a bogus string, such as <code>android:defaultValue="defaultRingtone"</code>:</p> <pre><code><RingtonePreference android:key="alarm" android:title="Alarm" android:name="Alarm" android:summary="Select an alarm" android:ringtoneType="alarm" android:showDefault="true" android:defaultValue="defaultRingtone" /> </code></pre> <p>When calling <code>PreferenceManager.setDefaultValues()</code>, grab the preference, and check if the bogus string is being stored:</p> <pre><code>// Set the stored preferences to default values defined in options.xml PreferenceManager.setDefaultValues(this, R.layout.options, false); // Check the stored string value, under the RingtonPreference tag final SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this); final String savedUri = savedState.getString("alarm", ""); // By default, set the alarm's URI to null Uri alarmUri = null; // Check if a String was actually provided if(savedUri.length() > 0) { // If the stored string is the bogus string... if(savedUri.equals("defaultRingtone")) { // Set the alarm to this system's default alarm. alarmUri = Settings.System.DEFAULT_ALARM_ALERT_URI; // Save this alarm's string, so that we don't have to go through this again final SharedPreferences.Editor saveEditor = saveState.edit(); saveEditor.putString("alarm", alarmUri.toString()); saveEditor.commit(); } // Otherwise, retrieve the URI as normal. else { alarmUri = Uri.parse(savedUri); } } </code></pre>
