My android radio app automatically close when I click back button

I am trying to run my Android radio app in the background. So when I click the back button after a little time it has been forced to stop. Automatically calls the onDestroy() method. How do I fix this problem?

This is the main activity class onBackPressed() button code.

 @Override
    public void onBackPressed(){
        System.out.println("onBackPressed");
        serviceIntent.addCategory(Intent.CATEGORY_HOME);
        serviceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(serviceIntent);
        moveTaskToBack(true); 
       //activity.moveTaskToBack(true);
    }

This is the console log

> I/System.out: onPrepared I/System.out: onBackPressed I/System.out:
> onDestroy I/System.out: onDestroy1 I/System.out: onDestroy2
