Try this.

AlertDialog.Builder alertDialog  = new AlertDialog.Builder(myContext);

Edit.

Sorry about no comment. Put Context which started your service like a instance in service and use it.

class SomeService 
{   
     private final Context myContext;
     public WebService(Context myContext) 
     {

        this.myContext= myContext;
     }

   public void showDialog()
   {
        AlertDialog d = new AlertDialog.Builder(myContext);
   }
}
