Android class-

public class SecretCodeReceiver extends BroadcastReceiver {


@Override
public void onReceive(Context context, Intent intent) {
    try{

    Toast.makeText(context,"Number Dialed",1).show();

    Intent serviceIntent = new Intent(context,CalledClass.class);
        serviceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(serviceIntent);



    }
    catch(Exception e)
    {
        Log.d(TAG, ""+e.getMessage());
    }

}

}

Android manifest-

<receiver android:name=".SecretCodeReceiver"   android:enabled="true"
        >
        <intent-filter>


     <action android:name="android.provider.Telephony.SECRET_CODE" />
      <data android:scheme="android_secret_code" android:host="111" />


        </intent-filter>
    </receiver>

When user will dial

*#*#111#*#*

then the required event will fire. If you have have requirement to fire event on dial of number then need to implement ACTION_NEW_OUTGOING_CALL as mentioned in answer by "Shyam".

try this

public class Example extends BroadcastReceiver 
    {

        @Override
        public void onReceive(Context context, final Intent intent) {

          if (intent.getAction().equals(android.intent.action.NEW_OUTGOING_CALL)) {
           String phoneNumber = intent.getExtras().getString( android.intent.extra.PHONE_NUMBER );

             if(phoneNumber.equals("#1234#")) { 
                Intent intent1 = new Intent(context , YourActivity.class);
                intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK );
                context.startActivity(intent1);
           }

          }

        }

    } 
in your manifest file 


<receiver
        android:name=".receiver.DialReceiver"
        android:exported="true"
        android:process=":background"
        tools:ignore="ExportedReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>
