by using the deep links in Android, you can open your app by clicking a link 

1/  Create A New Project: ( DeepLink Android Example )

2/  Modify your AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <application
        android:allowBackup="true"
        android:dataExtractionRules="@xml/data_extraction_rules"
        android:fullBackupContent="@xml/backup_rules"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.DeepLinkAndroidExample"
        tools:targetApi="31">
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

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

                <data
                    android:scheme="https"
                    android:host="tutorialb.com"
                    android:pathPrefix="/post" />
             <data
                    android:scheme="http"
                    android:host="tutorialb.com"
                    android:pathPrefix="/post" />
            </intent-filter>
        </activity>
    </application>

</manifest>

1/  In the intent filter data tag here you can put your website hostname and the path prefix to open the link in your app

<data
    android:scheme="https"
    android:host="tutorialb.com"
    android:pathPrefix="/post" />

1/  Modify your MainActvity.java

to know which link you opened in your app

package com.example.deeplinkandroidexample;

import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.widget.Toast;

import androidx.activity.EdgeToEdge;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.graphics.Insets;
import androidx.core.view.ViewCompat;
import androidx.core.view.WindowInsetsCompat;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        EdgeToEdge.enable(this);
        setContentView(R.layout.activity_main);
        ViewCompat.setOnApplyWindowInsetsListener(findViewById(R.id.main), (v, insets) -> {
            Insets systemBars = insets.getInsets(WindowInsetsCompat.Type.systemBars());
            v.setPadding(systemBars.left, systemBars.top, systemBars.right, systemBars.bottom);
            return insets;
        });

        Intent intent = getIntent();
        Uri data = intent.getData(); 

        if (data != null) {
            String deepLinkInfo = data.toString();
            Toast.makeText(this, "Deep Link Data: " + deepLinkInfo, Toast.LENGTH_SHORT).show();
        }
    }
}
