Android onActivityResult is not being called

This question has been raised on multiple threads but their solutions are not working for me.

This is my manifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.intent"
      android:versionCode="1"
      android:versionName="1.0">
<uses-sdk android:minSdkVersion="8"
          android:targetSdkVersion="23"/>
<application android:icon="@drawable/icon"
             android:label="@string/app_name"
             android:allowBackup="false">
    <activity android:name=".Start">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>
    <activity android:name=".Second"/>
</application>
</manifest>

This my Launch Class

package com.example.intent;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;

public class Start extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Toast.makeText(this, "First Intent", Toast.LENGTH_LONG).show();
    Intent intent = new Intent(this, Second.class);
    startActivityForResult(intent, RESULT_OK);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Toast.makeText(this, "After Intent", Toast.LENGTH_LONG).show();
}
}

This is my Second Class

package com.example.intent;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;

public class Second extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Toast.makeText(this, "Second Intent", Toast.LENGTH_LONG).show();
}
}

Now according to the code, the onActivityResult function in Start class should be called when I press the back button on Second Activity class, but its not being called since I am unable to see any Toast stating After Intent.

Please rectify me and provide a solution for this. Thanks.

The method onActivityResult isn't being called because you should set the return code in your Second Class.

The Official Documentation says:

When an activity exits, it can call setResult(int) to return data back to its parent. It must always supply a result code, which can be the standard results RESULT_CANCELED, RESULT_OK, or any custom values starting at RESULT_FIRST_USER.

To set a result code, use the method setResult before the activity is being closed.

Add the following line to your second class:

setResult(RESULT_OK)

For example, you can override the method onBackPressed and put setResult there, like this:

@Override
public void onBackPressed()
{
     setResult(RESULT_OK)
     super.onBackPressed();  
}

replace RESULT_OK in startActivityForResult(intent, RESULT_OK); with some custom constant, a positive number. RESULT_OK is -1
