I know that for opening android application from a link inside a web page we have to write the following in the AndroidManifest.xml:

        <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=my_scheme android:host=my_host />

        </intent-filter>

The problem is that I wrote it in the following way:

        <intent-filter>

            <action android:name=my_action/>

            <category android:name=android.intent.category.DEFAULT />

            <category android:name=android.intent.category.BROWSABLE />

            <data android:scheme=my_scheme android:host=my_host />

        </intent-filter>

I didn't add android.intent.action.VIEW and instead I added my own action that i made.
I can't change it because the version is already released.

The question is,

if there's a way to make the application run from JavaScript or simple
html page, maybe by defining the specific action in the page?

Thanks,

Paz.

SOLVED:

Thanks to David I found a solution:

<a href=intent://my_host#Intent;scheme=my_scheme;action=my_action;end>Link to my stuff</a>
