mediaStorageDir.mkdirs() not creating directory

Does anyone know a way around this problem? I am using a camera intent to take pictures. The following method generates the file where the picture would be stored. However, mkdirs() is not able to create the directory on the device. What are my options in such a situation?

private static File getOutputMediaFile() {
    File mediaStorageDir = new File(
        Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
        "MyCameraApp");
    if (!mediaStorageDir.exists()) {
        if (!mediaStorageDir.mkdirs()) {
            Log.d("MyCameraApp", "failed to create directory");
            return null;
        }
    }
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
        .format(new Date());
    return new File(mediaStorageDir.getPath() + File.separator + "IMG_"
        + timeStamp + ".jpg");
}

error log:

Have you added http://developer.android.com/reference/android/Manifest.permission.html#READ_EXTERNAL_STORAGE and http://developer.android.com/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE to your manifest?
