Android intentService Guidance

Question

After spending near a full week copying and pasting about every example online, I have come to realise that I just don't understand serviceIntent.

I understand the theory(I think), it's just it never works for me when I try. I have stripped my existing code, leaving only what's necessary to ask this question, using 'println' to demonstrate a working example or not. Could you guys tell me where I am going wrong. Thanks.

If it's important, I am only using AIDE. I have checked if AIDE has limitations in regards to intentservices but have found nothing to say not.

MAINACTIVITY.JAVA

package com.mycompany.rns;

imports are listed here...

public class MainActivity extends Activity {

    public class MyService extends IntentService {

        public MyService(){
            super("MyService");
        }

        @Override
        protected void onHandleIntent(Intent intent) {
            system.out.println("At fucking last!");
        }
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Intent k = new Intent(this,MyService.class);
        startService(k);
    }
}

MANIFEST.XML

</activity>
<service
    android:name=".MyService"
    android:enabled="true"
    android:exported="false" />
</application>

As Ahmed Ewiss has given a correct answer, but not created an answer that I can accept, using his advice, this is for everyone else as a simple template they can use...

MAINACTIVITY.JAVA

package com.mycompany.rns;

imports are listed here...

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Intent k = new Intent(this,MyService.class);
        startService(k);
    }
}

MYSERVICE.JAVA

package com.mycompany.rns;

imports are listed here...

public class MyService extends IntentService {

    public MyService(){
        super("MyService");
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        system.out.println("At fucking last!");
    }
}

MAIN.XML

</activity>
<service
     android:name=".MyService"
     android:enabled="true"
     android:exported="false" />
</application>

The working solution was to seperate the MainActivity.java file from the Service.java file. class file.
