Cannot implement deeplinks in ionic 4 beta

#1

I tried to use ionic deeplinks in my application,

<plugin name="ionic-plugin-deeplinks" spec="1.0.17">
        <variable name="URL_SCHEME" value="sportx" />
        <variable name="DEEPLINK_SCHEME" value="https" />
        <variable name="DEEPLINK_HOST" value="sportxindia.com" />
        <variable name="ANDROID_PATH_PREFIX" value="/" />
    </plugin>

This is my config.xml looks like, and I wrote script like window.location.href=“sportx://sportxindia.com”, but no luck.
Can somebody help me?
