This works from Android 2.2 to 4.0 and now after adding the try catch to the last line it works for 4.1.2 and 4.2 Frankly speaking dont know how it works but it works for me.

          Log.d(tag, "InSecond Method Ans Call");
    // froyo and beyond trigger on buttonUp instead of buttonDown
    Intent buttonUp = new Intent(Intent.ACTION_MEDIA_BUTTON);
    buttonUp.putExtra(Intent.EXTRA_KEY_EVENT, new KeyEvent(
            KeyEvent.ACTION_UP, KeyEvent.KEYCODE_HEADSETHOOK));
    sendOrderedBroadcast(buttonUp, "android.permission.CALL_PRIVILEGED");

    Intent headSetUnPluggedintent = new Intent(Intent.ACTION_HEADSET_PLUG);
    headSetUnPluggedintent.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY);
    headSetUnPluggedintent.putExtra("state", 0);
    headSetUnPluggedintent.putExtra("name", "Headset");
    try {
        sendOrderedBroadcast(headSetUnPluggedintent, null);
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

This is working for me in Android 4.1.2 as well as i have tested on 4.2 This still gives an exception which is handled.
