Getting Event Injector Permission

Question

Hi all,

I am trying to get permission for EventInjector . I want to capture Image from the camera and display that image in my application , and for this i need to have EventInjector Permission. My code to get Permission is like:

try{
      final ApplicationPermissionsManager appPermissionsManager = ApplicationPermissionsManager.getInstance();
  final ApplicationPermissions permissions = new ApplicationPermissions();
  int[] keys = permissions.getPermissionKeys(); 
  for (int i = 0; i < keys.length; i++) {
           int key = keys[i];
           if(key == ApplicationPermissions.PERMISSION_EVENT_INJECTOR);
           {
            hasAppPermission = true;
            break;
           }
       }
  if(!hasAppPermission)
  {
   UiApplication.getUiApplication().invokeAndWait(new Runnable(){
   public void run(){
   permissions.addPermission( ApplicationPermissions.PERMISSION_EVENT_INJECTOR );
   if(permissions.getPermission( ApplicationPermissions.PERMISSION_EVENT_INJECTOR) != ApplicationPermissions.VALUE_ALLOW)
   appPermissionsManager.invokePermissionsRequest( permissions );
    }
   });
  }

  if(!permissions.containsPermissionKey(ApplicationPermissions.PERMISSION_EVENT_INJECTOR));
          permissions.addPermission( ApplicationPermissions.PERMISSION_EVENT_INJECTOR );
         if(permissions.getPermission( ApplicationPermissions.PERMISSION_EVENT_INJECTOR) != ApplicationPermissions.VALUE_ALLOW)
  { 
  }
  else
   System.out.println("*********Permission is already set******");
   }catch(Exception e){
   System.out.println("Exception caught :" + e);

The problem is that i am not prompted for any permission when i capture the image and my application is denied the permission.

Thanx in advance..
