Camera error on calling the intent. Android

Question

I am not sure why I am getting an error.

Camera error Can't connect to the camera.

Here is my code for the intent (and yes I have the permission in the manifest file)

 final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "MyDir" + File.separator);
                    root.mkdirs();
                    final String fname = getUniqueImageFilename();
                    final File sdImageMainDirectory = new File(root, fname);
                    outputFileUri = Uri.fromFile(sdImageMainDirectory);
                    // Camera.
                    final List<Intent> cameraIntents = new ArrayList<Intent>();
                    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    final PackageManager packageManager = getActivity().getPackageManager();
                    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
                    for (ResolveInfo res : listCam) {
                        final String packageName = res.activityInfo.packageName;
                        final Intent intent = new Intent(captureIntent);
                        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
                        intent.setPackage(packageName);
                        intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
                        cameraIntents.add(intent);
                    }

                    final Intent chooserCameraIntent = Intent.createChooser(captureIntent, "Use Camera");

                    startActivityForResult(chooserCameraIntent, YOUR_SELECT_PICTURE_REQUEST_CODE);

Here is the logcat error:

If a camera app crashes, it can lock up the camera hardware, preventing it from being used again until the device is rebooted. Hence, if you run into "cannot open camera" and similar sorts of messages, try rebooting the device to see if the problem clears up.
