I have figured out how this is done for Sony devices.

I've blogged about it here. I've also posted a seperate SO question about this here.

Sony devices use a class named BadgeReciever.

Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:

Broadcast an Intent to the BadgeReceiver:

Intent intent = new Intent();

intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");

sendBroadcast(intent);

Done. Once this Intent is broadcast the launcher should show a badge on your application icon.
To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:
```
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
```

I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.

Android   vanilla  android without custom launchers and touch interfaces  does not allow changing of the application icon  because it is sealed in the  apk tightly once the program is compiled  There is no way to change it to a  drawable  programmatically using standard APIs  You may achieve your goal by using a widget instead of an icon  Widgets are customisable  Please read this  http   www cnet com 8301-19736 1-10278814-251 html and this http   developer android com guide topics appwidgets index html  Also look here  https   github com jgilfelt android-viewbadger  It can help you  As for badge numbers  As I said before - there is no standard way for doing this  But we all know that Android is an open operating system and we can do everything we want with it  so the only way to add a badge number - is either to use some 3-rd party apps or custom launchers  or front-end touch interfaces  Samsung TouchWiz or Sony Xperia s interface  Other answers use this capabilities and you can search for this on stackoverflow  e g  here  But I will repeat one more time  there is no standard API for this and I want to say it is a bad practice  App s icon notification badge is an iOS pattern and it should not be used in Android apps anyway  In Andrioid there is a status bar notifications for these purposes http   developer android com guide topics ui notifiers notifications html  So  if Facebook or someone other use this - it is not a common pattern or trend we should consider  But if you insist anyway and don t want to use home screen widgets then look here  please  How does Facebook add badge numbers on app icon in Android  As you see this is not an actual Facebook app it s TouchWiz  In vanilla android this can be achieved with Nova Launcher http   forums androidcentral com android-applications 199709-how-guide-global-badge-notifications html So if you will see icon badges somewhere  be sure it is either a 3-rd party launcher or touch interface  frontend wrapper   May be sometime Google will add this capability to the standard Android API
