BlackBerry - Possible to Hide Video Field?

I want to write an application like a Flashlight (with the help of the camera LED).


Player player = javax.microedition.media.Manager.createPlayer("capture://video?encoding=video/3gpp");player.realize();

VideoControl videoControl =(VideoControl) player.getControl("VideoControl");

if(videoControl !=null){ videoField =(Field)videoControl.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE,"net.rim.device.api.ui.Field");

try{ videoControl.setDisplaySize(1,1);

}catch(Exception e){


} videoControl.setVisible(true); add(videoField);FlashControl flashControl =(FlashControl) player.getControl("javax.microedition.amms.control.camera.FlashControl"); setFlashlight(true);}player.start();


The code above works perfectly, but I want to hide the videoField. When I removedadd(videoField) or use videoControl.setVisible(false), the flashlight does not work. Can someone explain why?



How I can turn lights on with a hidden videoField?

Re: BlackBerry - Possible to Hide Video Field?

This looks like it should be in the Java Development forum. On BBOS, you cannot hide the viewfinder (by design)


On BB10, you don't have to display it if you don't want to.
