             <data android:name="android.intent.action.VIEW" />
             <category android:name="android.intent.category.DEFAULT" />
             <category android:name="android.intent.category.BROWSABLE" />
         </intent-filter>    
    </activity>
</application>

HTML code

<a href="afs.com.afs:75235">Launch Application</a>

Answer 1

Attributes from documentation scheme://host:port/path or pathPrefix or pathPattern.

You need to change define proprely scheme and host definition. If you don't specify scheme then all URI attributes will be ignored, and won't be applied.

You could use http URI scheme.

    <data android:scheme="http" android:host="afs.com.afs"/>

and in HTML

<a href="http://afs.com.afs:75235">Launch Application</a>

Or define own URL scheme.

    <data android:scheme="myapp" android:host="afs.com.afs"/>

and in HTML

<a href="myapp://afs.com.afs:75235">Launch Application</a>

PS.

Change this

    <data android:name="android.intent.action.VIEW" />

to

    <action android:name="android.intent.action.VIEW" />
