Ringtone Preference not saving choice

Question

I have a ringtone preference in my app but when I select the tone I want, it does not get stored in the preference value. I can click the preference again and it will not show what I just selected.

here is the XML

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="Audio Settings">
        <CheckBoxPreference 
            android:key="SMS_PREF_TTS"
            android:title="Say name of sender"
            android:summary="When a person in your contact list sends you a sms/mms message its says their name"
            android:defaultValue="false">
        </CheckBoxPreference>
        <CheckBoxPreference 
            android:key="SMS_PREF_TTS_MSG"
            android:title="Say Message"
            android:summary="Will say the message of sender from contact list"
            android:dependency="SMS_PREF_TTS"
            android:defaultValue="false">
        </CheckBoxPreference>
        <RingtonePreference 
            android:key="SMS_PREF_SOUND"
            android:title="Change Sound"
            android:ringtoneType="notification"
            android:summary="Select the notification Sound"
            android:dialogTitle="Change Sound"
            android:defaultValue="Silent">
        </RingtonePreference>
</PreferenceCategory>
</PreferenceScreen>

and the weird thing is I just wrote another xml for another part of my app with a ringtone preference looking the same way and that one works so I dont understand.

here is the working one

<RingtonePreference
        android:key="CAL_PREF_TONE"
        android:title="Default ringtone"
        android:summary="Select default notification ringtone"
        android:ringtoneType="notification"
        android:defaultValue="Silent"
        android:dependency="CAL_PREF_ON">
    </RingtonePreference>

Answer 1

If you have overriden onActivityResult() and forgotten to call super.onActivityResult() you can see this problem as well.

See RingtonePreference not firing OnPreferenceChangeListener

Answer 2

I had the same problem. In the AndroidManifest.xml file I had my preference activity set with noHistory="true". Once I removed it everything worked correctly.
