Starting activity in android via Dialpad using secret code

Question

I just want to start activity through the Secret Code .

Although there are many solutions to this problem, none of them worked for me. It seems that BroadcastReceiver not be heard.

I am using Mi4i MIUI 7.

Here is my code. Please, help!

MainActivity.java

package com.example.jatin.myapplication2;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
    }

}

I even tried the code below, but that didn't work.

MySecretCodeReceiver.java

package com.example.jatin.myapplication2;

import android.content.BroadcastReceiver;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

 /**
 * Created by Jatin on 05-Aug-16.
 */
 public class MySecretCodeReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("android.provider.Telephony.SECRET_CODE")) {
        String uri  =  intent.getDataString();
        String sep[] = uri.split("://");
        if (sep[1].equalsIgnoreCase("1234"))
        {
            Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage("com.example.jatin.myapplication2.MainActivity");
            context.startActivity(launchIntent);

        }
        else if (sep[1].equalsIgnoreCase("5678")) {
            Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage("net.one97.paytm");
            context.startActivity(launchIntent);
        }

//            Intent i = new Intent(context, MainActivity.class);
//            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//            setResultData(null);
//            context.startActivity(i);

       }
    }

}

I also tried putting android: host = "1234" in the manifest, still not getting the desired results

AndroidManifest.xml

  <?xml version="1.0" encoding="utf-8"?>

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
<receiver android:name="receivers.MySecretCodeReceiver"
    android:enabled="true"
    android:exported="true"
    android:permission="android.permission.PROCESS_OUTGOING_CALLS">
    <intent-filter>
        <action android:name="android.provider.Telephony.SECRET_CODE"  />
        <data android:scheme="android_secret_code" />
    </intent-filter>
</receiver>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"

    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
