How to show batch no on application icon?

In iPhone we can show the batch num开发者_开发问答ber on the application icon. i want to do the same thing for Android application icon.

I have seen the same thing in Android "Message" application icon. I you receive one message, it will show "1" on the icon.

We can use Widget to do this. But I don't want to use Widget.

Is there any possibility to do this without widgets ?

Please give some idea about this.

No, sorry.

BTW, they are called "app widgets". "Widgets" are things like EditText and Button.
