I want to pass parameters to the app with int://

"I will reply to ""Specific Page in the App"" by replacing it with ""Specific Activity""

The rest is
https://developer.chrome.com/multidevice/android/intents
There is no concept of "file path" as described in the section.

Just in case, I will include an example below.

Link Side: ([] is a descriptive parenthesis and is not actually required)

<a href="intent://[hostname]/#Intent;scheme=[schemename]; package=[packagename];category=android.intent.category.category.BROWSABLE;action=android.intent.action.VIEW;end;">Test Link>

Manifest side

<activity android:name=".Activity "> you want to launch
    <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="scheme name"
            android: host="hostname"/>
    </intent-filter>

Action/Category can be added as needed, but category.BROWSABLE on the manifest side seems to be required.

If you just want to start the application, you should be able to start it only with scheme and host.
If the application is not installed by adding a package, we will go to find the package.

In addition, if you want extra information, etc., the following command is useful for assembling the int:schema string.

adb shell am to-intent-uri
