This question already has an answer here:
The following question which was migrated from stats.stack-exchange.com, has been locked.
I tried to edit the question, because It could be written as
How Can I scan and get information from a bar-code using an Android Device
In my opinion, the conceivable way that such a question can be closed is by
"exact duplicate", but It's not only been closed, but it's been locked.
According to What is a "locked" post?, A post can be locked when
- A question or answer where repeated voting or editing is happening in a way which attempts to game, hack, or otherwise abuse the system.
- A question that gets opened and closed repeatedly many times without achieving community consensus on whether it should stay open or closed.
- A question that, for whatever reason, continues to attract flame posts, spam, or other inappropriate answers.
- A question that is repeatedly vandalized by its asker; for example, to drastically alter the meaning of the question that invalidates existing answers, or to obliterate/obscure the question.
As far As I can tell, this question meets none of those criteria.
I can understand that the question was closed. It wasn't formed very well and It was almost certainly a duplicate, but why Locked?
