title: adding notification badge on app icon in android
body: <p>you may think that this is a duplicate question but i want answers to be more specific than any questions that are similar to this.</p>
  
  <p>first it says that like facebook having notification badge with samsung device.
  <a href="https://stackoverflow.com/questions/17510419/how-does-facebook-add-badge-numbers-on-app-icon-in-android">How does Facebook add badge numbers on app icon in Android?</a>. and it turns out to be the touchwiz launcher which may be the default launcher of samsung devices. when i tried to test my samsung device with nova launcher. it needs to install some third party software or Nova TestlaUnread.</p>
  
  <p>Heres the fact. i thought the touchWiz is adding badge for all application, but when i try to test with my app to have some notification, it doesn't show any badge. as i found out that samsung TouchWiz only showing app to selected app as stated here:
  <a href="https://stackoverflow.com/questions/8476544/ui-help-for-notification-on-icon">UI help for Notification on icon</a></p>
  
  <p><code>The question is: is there any way to let know the touchWiz to add badge to my app-icon?</code>
  That's for the samsung device,</p>
  
  <p>with that previous arguments, it seems like the launcher of different vendors are the one responsible for the badges in app icon in android. Sony Experia uses Experia Home/Launcher as its default launcher. in my sony device, they had some badge in there sms or miss calls or facebook. </p>
  
  <p><code>The question is: like the previous question, is there any way to let know experia home to add badge to my app icon?</code></p>
  
  <p>because i was thinking maybe interacting with the launcher seems the solution of this "adding badge to app icon". </p>
  
  <p>and there's this solution about this activity alias and changing the app icon from time to time which i think is rubbish.

  <p>so i'm seeking solution on interacting with the launchers which is vendor specific.</p>
  
  <p>'any solution will be appreciated even i would go deep with using native development in android'</p>
  
  <p>Thanks ahead</p>
