Fixed version (ground truth):

  mPostUploadNotifier.updateNotificationNewPost(mPost,uploadingPostTitle,uploadingPostMessage);
  mSite=mSiteStore.getSiteByLocalId(mPost.getLocalSiteId());
  if (mSite == null) {
    mErrorMessage=mContext.getString(R.string.blog_not_found);
    return false;
  }
  if (TextUtils.isEmpty(mPost.getStatus())) {
    mPost.setStatus(PostStatus.PUBLISHED.toString());
  }
  String content=mPost.getContent();
