android.hardware.Camera$EventHandler.handleMessage

Try this code and try to save image or video in background thread instead of UI

private PictureCallback mPicture = new PictureCallback() {            @Override            public void onPictureTaken(final byte[] data, Camera camera) {                final File pictureFile = getOutputMediaFile();                if (pictureFile == null) {                    return;                }                Thread thread = new Thread() {                    @Override                    public void run() {                        try {                            FileOutputStream fos = new FileOutputStream(pictureFile);                            fos.write(data);                            fos.close();                        } catch (Exception e) {                            e.printStackTrace();                        }                    }                };                thread.start();            }        };        private File getOutputMediaFile() {            File mediaStorageDir = new File(                    Environment.getExternalStorageDirectory(),                    "/Images");            if (!mediaStorageDir.exists()) {                if (!mediaStorageDir.mkdirs()) {                    Log.d("Camera", "failed to create directory");                    return null;                }            }            // Create a media file name            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")                    .format(new Date());            File mediaFile;            String image_path = mediaStorageDir.getPath() + File.separator                    + "IMG_" + timeStamp + ".jpg";            mediaFile = new File(image_path);            return mediaFile;        }

When data dose not created.You can not use bitmap.

That means a little time need to create image.so bitmapcreate return null.

I think PictureCallback runs like a Thread

To resolve this problem. change this code

   Bitmap bMap= BitmapFactory.decodeFile(cPath);   Bitmap out = Bitmap.createScaledBitmap(bMap, 1024, 768, true);

To

    Bitmap bMap = BitmapFactory.decodeByteArray(data, 0,.length);    Bitmap out = Bitmap.createScaledBitmap(bMap, 1024, 768, true);

That code convert byte[] to bitmap (see data in picturecallback );
