you can use http://www.blackberry.com/developers/docs/7.1.0api/net/rim/blackberry/api/homescreen/HomeScreen.html... (since 6.0), on earlier OS versions you would have to replace the application icon.

hey simon thanks for replay i know that  and i tried use that like  HomeScreen.setNewState(true). but it is not working. 

i want to set this HomeScreen.setNewState(true) to UI application from background thread.  and i tried with this also

int handler = CodeModuleManager.getModuleHandle("JAM");
ApplicationDescriptor appDescriptor = CodeModuleManager.getApplicationDescriptors(handler)[0];
ApplicationDescriptor appDescriptor = CodeModuleManager.getApplicationDescriptors()[0];
HomeScreen.setNewState(true,appDescriptor);

it is working but throwing the exception after some time because of Module handles can be transitory.

Thanks

maybe you can decide to solve a single problem in a single thread?
