Kodi 21 cannot add external players



[font][font]I created the playercorefactory.xmlplayercorefactory.xmlplayercorefactory.xml file and used it normally on kodi 20.5. But when I copy this file to the userdata folder in kodi 21 stable, it no longer works.
I don’t know what to do to use an external player on kodi 21
This is the code playercorefactory.xml in my file
<playercorefactory> [/font][/font]
[font][font]    <players> [/font][/font]
[font][font]        <player name=”Zidoo Player” type=”ExternalPlayer” audio=”false” video=”true”> [/font][/font]
[font][font]            <filename>com.android.gallery3d</filename> [/font][/font]
[font][font]            <hidexbmc>true</hidexbmc> [/font][/font]
[font][font]            <playcountminimumtime>120</playcountminimumtime> [/font][/font]
[font][font]        </player> [/font][/font]
[font][font]    </players> [/font][/font]
[font][font] <rules action=”prepend”> [/font][/font]
[font][font]  <rule video=”true” player=”Zidoo Player”> [/font][/font]
[font][font]  </rule> [/font][/font]
[font][font] </rules> [/font][/font]
