Answer 1

This below code may help you:
Add this to Main Screen which you want to show the camera:
captureImage=new MenuItem("Capture Images",10,100)
{
public void run()
{
synchronized (Application.getEventLock())
{
captureImage();
}
}
};
addMenuItem(captureImage);
The code for captureImage() method is:
private void captureImage()
{
try
{
player = javax.microedition.media.Manager.createPlayer("capture://video?encoding=jpeg&width=1024&height=768");
player.realize();
_videoControl = (VideoControl) player.getControl("VideoControl");
if (_videoControl != null)
{
Field videoField = (Field) _videoControl.initDisplayMode (VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");
_videoControl.setDisplayFullScreen(true);
_videoControl.setVisible(true);
player.start();
if(videoField != null)
{
add(videoField);
}
}
}
catch(Exception e)
{
if(player!=null)
{
player.close();
}
Dialog.alert(e.toString());
}
}
The below code is save the image into the sdcard or device card. Override the invokeAction(int action) Method
protected boolean invokeAction(int action)
{
boolean handled = super.invokeAction(action);
if(SdcardTest.SdcardAvailabulity())//I am checking here that the sdcard is there of or not.....?
{
//PATH = "file:///SDCard/BlackBerry/pictures/"+"Image_"+System.currentTimeMillis()+".jpg";
PATH = System.getProperty("fileconn.dir.memorycard.photos")+"Image_"+System.currentTimeMillis()+".jpg";//here "str" having the current Date and Time;
}
else
{
PATH = System.getProperty("fileconn.dir.photos")+"Image_"+System.currentTimeMillis()+".jpg";
}
if(!handled)
{
if(action == ACTION_INVOKE)
{
try
{
byte[] rawImage = _videoControl.getSnapshot(null);
fileconn=(FileConnection)Connector.open(PATH);
if(fileconn.exists())
{
fileconn.delete();
}
fileconn.create();
OutputStream os=fileconn.openOutputStream();
os.write(rawImage);
fileconn.close();
os.close();
Status.show("Image is Captured",200);
if(player!=null)
player.close();
}
catch(Exception e)
{
if(player!=null)
{
player.close();
}
if(fileconn!=null)
{
try
{
fileconn.close();
}
catch (IOException e1)
{
//if the action is other than click the trackwheel(means go to the menu options) then we do nothing;
}
}
}
}
}
return handled;
}

try this for image snap
Note: you can not store in resource folder you can only store in SDcard
class screen extends MainScreen implements FieldChangeListener
{
private VideoControl vc;
private String encoding;
private Player p;
private Field viewFinder;
private BitmapField bitmapField;
private ButtonField btn;
public screen() {
btn=new ButtonField("snap",Field.FOCUSABLE);
btn.setChangeListener(this);
add(btn);
}
public void fieldChanged(Field field, int context) {
if(field==btn)
{
try{
p = Manager.createPlayer("capture://video");
p.realize();
p.prefetch();
p.start();
vc = (VideoControl) p.getControl("VideoControl");
viewFinder = (Field)vc.initDisplayMode(VideoControl.USE_GUI_PRIMITIVE, "net.rim.device.api.ui.Field");
vc.setVisible(true);
final String imageType = "encoding=jpeg&width=640&height=480&quality=superfine";
UiApplication.getUiApplication().invokeLater(new Runnable(){
public void run(){
byte[] image = vc.getSnapshot(imageType);
FileConnection conn = (FileConnection)Connector.open("file:///store/home/user/pictures/"+System.currentTimeMillis()+".jpeg", Connector.READ_WRITE);
conn.create();
OutputStream out = conn.openOutputStream();
out.write(image);
out.flush();
out.close();
conn.close();
Bitmap image1 = Bitmap.createBitmapFromBytes(imageBytes, 0, imageBytes.length, 4);
bitmapField.setBitmap(image1);
add(bitmapField);
}
});
} catch (Exception me){
}
}
}
}

if you want to save an image from camera to your device you can use the following code.
try
{
focusControl.startAutoFocus();
byte[] image = videoControl.getSnapshot(null);
String message = "Captured "+image.length+" bytes of JPG data";
debug(message);
FileConnection conn = (FileConnection)Connector.open("file:///store/home/user/pictures/"+(new Date()).getTime()+".jpg", Connector.READ_WRITE);
conn.create();
OutputStream out = conn.openOutputStream();
out.write(image);
out.flush();
out.close();
conn.close();
Dialog.alert(message);
}
catch (Exception e) {
Dialog.alert("Capture failed due to: "+e.getMessage());
}

If you want to save the images in your Project/res or Project/src during runtime, you cant do that.
You can save image in SDcard/device.
Why would you want to save it in your project source?
