One assembly for two different versions (4.6.4.7 and 5.0 + above) in blackberry

I want to import facebook libraries for BlackBerry 5.0 and higher and I do not want to import these libraries for 4.6 and 4.7.

I tried to use preprocessors for 4.7 and above, giving the link below: http://smartfone-more.blogspot.in/2010/05/coding-for-multiple-blackberry-devices.html

Now it works fine with JDE 4.7, but does not get the expected result for 5.0. Please find the code I tried:

//#ifdef JDE_4_7_0
import net.rim.device.api.ui.component.ButtonField;
//#else
import net.rim.device.api.ui.component.LabelField;
//#endif
import net.rim.device.api.ui.container.MainScreen;


public class TestScreen extends MainScreen{

        TestScreen(){

                //#ifdef JDE_4_7_0
                ButtonField btn = new ButtonField("Test Button");
                add(btn);
                //#else
                LabelField lbl1 = new LabelField("Test Label 1");

                add(lbl1);
                //#endif
        }
}

According to the code, I expect the result written in the else part for 5.0, and if the part for 4.7. I tested it on the device as well as on JDE.

Please, help.
