hi TreKing,
This is my whole code, Where is the appropriate place to close
the stream. or may i have to add a loop or thread to control this. please give
me the clear road map to handle this.
Thanks,
public void surfaceCreated(SurfaceHolder holder)
{
// The Surface has been created, acquire the camera and tell it where
// to draw.
try {
socket = new Socket("192.168.1.220", 8888);
obj = new ObjectOutputStream(socket.getOutputStream());
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
camera = Camera.open();
try {
camera.setPreviewDisplay(holder);
camera.setPreviewCallback(new PreviewCallback() {
// Called for each frame previewed
@SuppressWarnings("null")
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
int format = parameters.getPreviewFormat();
//YUV formats require more conversion
if (format == ImageFormat.NV21 /*|| format == ImageFormat.YUY2 ||
format == ImageFormat.NV16*/)
{
int w = parameters.getPreviewSize().width;
int h = parameters.getPreviewSize().height;
// Get the YuV image
YuvImage yuv_image = new YuvImage(data, format, w, h, null);
// Convert YuV to Jpeg
Rect rect = new Rect(0, 0, w, h);
ByteArrayOutputStream output_stream = new
ByteArrayOutputStream();
yuv_image.compressToJpeg(rect, 100, output_stream);
byte[] byt=output_stream.toByteArray();
try {
obj.writeObject(byt);
obj.flush();
// obj.close();
Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
}
Preview.this.invalidate();
}
}
});
} catch (IOException e) {
e.printStackTrace();
}
}

Thanks for your reply, Sorry i have not clearly mention that "obj" is the
object of the ObjectOutputStream, this stream send only the first image to
server not any other what's the reason.
Without more code to look at, the fact that you're closing the stream in the
function might be a factor.
