I use RingtonePreference and would like to use default notification sound as the default

  • 0

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=""
      />

LogCat of the exception:

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);
}
