How to set multiple default values in a MultiSelectListPreference?

Question

I have preference.xml like this

<MultiSelectListPreference
        android:key="store_select"
        android:title="@string/setting_store_title"
        android:summary="@string/setting_store_summary"
        android:dialogTitle="@string/setting_store_dialog_title"
        android:entries="@array/store_names"
        android:entryValues="@array/stores"
        android:defaultValue="@array/stores"
        />

with my two arrays:

    <string-array name="stores">
    <item>1</item>
    <item>2</item>
    <item>3</item>
    <item>4</item>
    <item>5</item>
</string-array>

<string-array name="store_names">
    <item>foodbasics</item>
    <item>nofrills</item>
    <item>metro</item>
    <item>loblaws</item>
    <item>sobeys</item>
</string-array>

I want the default behaviour to be all of the options selected, but currently nothing is selected by default. Am I doing something wrong?

To make all MultiSelectListPreference items selected (on) by default, then include the attribute defaultsValue for the Preference, e.g.

android:defaultValue="@array/stores"

If it's not working, then make sure that you clear the application data as this will only take effect the first time the application is run.
