String timeStamp = new SimpleDateFormat("HH:mm:ss").format(new Date());
String imageFileName = timeStamp + ".jpg";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
pictureImagePath = storageDir.getAbsolutePath() + "/" + imageFileName;
File file = new File(pictureImagePath);
Uri outputFileUri = Uri.fromFile(file);
intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
