How to set xmlns path in PreferenceScreen - modified ListPreferenceMultiSelect

Question

I have the code downloaded from site: http://blog.350nice.com/wp/archives/240

But on the line:

<com.threefiftynice.android.preference.ListPreferenceMultiSelect 

Is error code:

Multiple annotations found at this line:
    - error: No resource identifier found for attribute 'checkAll' in package 
     'com.threefiftynice.android'
    - error: No resource identifier found for attribute 'separator' in package 
     'com.threefiftynice.android'

This is XML with error:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen android:key="prefKey"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:threefiftyprefs="http://schemas.android.com/apk/res/com.threefiftynice.android">  
    <com.threefiftynice.android.preference.ListPreferenceMultiSelect 
        threefiftyprefs:checkAll="check" threefiftyprefs:separator="|"
        android:defaultValue="#ALL#"
        android:key="key"
        android:title="Image folders to monitor" android:dialogTitle="Image folders to monitor"
        android:summary="Specify which folders should be monitored for images"
        android:entries="@array/typeOfPoints"
        android:entryValues="@array/typeOfPointsID"/>
</PreferenceScreen>

I know xmlns and the path to ListPreferenceMultiselect ist bad - but I tried a lot of possible paths and problem was with all of them (this is the original path from the site with original packages). This is my structure of the code

:

How should I set the path to make it work? Thank you very much.

EDIT: After chanded it to xmlns:threefiftyprefs="schemas.android.com/apk/res-auto" it does not write error in xml but it throws error on run:

Answer 1

change the line

xmlns:threefiftyprefs="http://schemas.android.com/apk/res/com.threefiftynice.android"

to

xmlns:threefiftyprefs="http://schemas.android.com/apk/res-auto"

Answer 2

This is how it should be:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen android:key="prefKey"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:threefiftyprefs="schemas.android.com/apk/res-auto">  
    <goandknow.models.ListPreferenceMultiSelect 
    threefiftyprefs:checkAll="check" threefiftyprefs:separator="|"
    android:defaultValue="#ALL#"
    android:key="key"
    android:title="Image folders to monitor" android:dialogTitle="Image folders"
    android:summary="Specify which folders should be monitored for images"
    android:entries="@array/typeOfPoints"
    android:entryValues="@array/typeOfPointsID"/>
</PreferenceScreen>

Important:

xmlns:threefiftyprefs="schemas.android.com/apk/res-auto" goandknow.models.ListPreferenceMultiSelect Thanks to Sankar V.
