Hello @未凡fh,
Thank you for reaching out to us. Support on this forum is only being provided in the English language, as this serves our community best, and because we also simply do not speak all languages of the world. I think the language you posted in is Simplified Chinese, please excuse me when I wrong, but that is what Google said. No-one on the SDK Team speaks that language. And even if we would, we would refuse to answer in this language as it would lock out large parts of the community. As we do for requests which come in German, French, or Spanish (languages we do speak).
Running your request through Google Translate, I got this:
Let me ask: How do I detect an object moving and send a message when an object moves?
Please confirm that this is your request and that we can communicate in English.
Thank you for your understanding,
Ferdinand
