I use RingtonePreference and would like to use default notification sound as the default preference value. To achieve this I have followed advice in: RingtonePreference Default value
Sadly, in effect I got an InflateException that I cannot get rid of in any way. Is it a bug in android, my phone or am I doing something wrong?
My OnCreate method in MyPreferenceActivity class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
Relevant fragment of my preferences.xml:
<RingtonePreference
android:key="ringtone_preference"
android:ringtoneType="notification"
android:showDefault="true"
android:showSilent="true"
android:defaultValue="content://settings/system/notification_sound"
android:title="Notification sound"
android:summary=""
/>

I also tried inserting a string DEFAULT_NOTIFICATION_URI instead of content://settings/system/notification_sound, but without any success. After removing the android:defaultValue field completely, everything works fine apart from the fact, that default value of my preference is Silent ringtone instaed of the default notification sound, which is unacceptable for me.
I have searched everywhere and cannot find a solution to this problem. If nothing else works, I will use a hack posted here: https://stackoverflow.com/a/4298638/1265432, but I would like to solve this properly.
EDIT: Problem exists on both my CM9 Motorola Defy and in Emulators of 4.0.4 (API 15) and 2.1 (API 7), so I think the phone is not a problem. Bug, or am I doing something wrong?
I filed a bug report for Android here: http://code.google.com/p/android/issues/detail?id=33220
In the meantime, I use the following workaround, which I found cleaner than the one linked in the question. I modified OnCreate method of MyPreferenceActivity to this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Uri notificationSound = Uri.parse(PreferenceManager.getDefaultSharedPreferences(this)
.getString("ringtone_preference", System.DEFAULT_NOTIFICATION_URI.toString()));
if (notificationSound.equals(System.DEFAULT_NOTIFICATION_URI)) {
PreferenceManager.getDefaultSharedPreferences(this).edit()
.putString("ringtone_preference", System.DEFAULT_NOTIFICATION_URI.toString())
.commit();
}
addPreferencesFromResource(R.xml.preferences);
}
