Google provide online material for this: https://codelabs.developers.google.com/codelabs/deeplink-referrer

Summary

You can use Activity#getReferrer() to get the referrer of the deep link. It's available since API 22.

For API Level 21 and below, you can use the following snippet from above online material:

    private static final String REFERRER_NAME = "android.intent.extra.REFERRER_NAME";


 /** Returns the referrer on devices running SDK versions lower than 22. */
    private Uri getReferrerCompatible(Activity activity) {
        Intent intent = activity.getIntent();
        Uri referrerUri = intent.getParcelableExtra(Intent.EXTRA_REFERRER);
        if (referrerUri != null) {
            return referrerUri;
        }
        String referrer = intent.getStringExtra(REFERRER_NAME);
        if (referrer != null) {
            // Try parsing the referrer URL; if it's invalid, return null
            try {
                return Uri.parse(referrer);
            } catch (ParseException e) {
                return null;
            }
        }
        return null;
    }

depending on @Ahmad Fadli answer (works but some application might not be detected) I had a similar use case, so someone might need it , you could use both of them too :

fun getReferrerCompatible(activity: Activity?): String? {
    if (activity == null)
        return null
    try {
        val intent = activity.intent
        val bundle = intent.extras
        if (bundle != null) {
            val keySet = bundle.keySet().toTypedArray()
            for (k in keySet) {
                if (k.contains("application_id")) {
                    return bundle.getString(k)
                }

            }
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
            return activity.referrer?.toString()
        }
    } catch (e: Exception) {
        Crashlytics.logException(e)
    }
    return null
}

the default referrer actually does not give you chrome application for some deep links ,for some reason it would return "google.com"

Try this

On your android manifest file register your acitivity which have to open on link click

 <activity
            android:name=".YOURACTIVITY"
            android:label="@string/app_name"
            android:configChanges="keyboardHidden|orientation|screenSize"
            android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.VIEW"/>
                <category android:name="android.intent.category.DEFAULT"/>
                <category android:name="android.intent.category.BROWSABLE"/>
                <data android:scheme="http"
                    android:host="somedomainname.com"
                    android:pathPrefix="/index"/>

            </intent-filter>

        </activity>

On your html 

<a href="android-app:/your android app packagename/http://somedomainname.com/index">Click me</a>
