How does Gmail handle attachments in Android

Question

I want to send an attachment from my app. I start an ACTION_SEND intent with the file URI that I want to attach.

I can get a callback to my app when the user clicks SEND, but since uploading the attachment can take a while how do I know if the email is actually sent?

I need to know this since I want to delete the file after. What happens if the file is deleted in the meantime?

在处理程序中使用线程并删除处理程序.post中的文件，尽管您必须自己进行测试，但这可能仍然有效...
