如何从Android应用程序发送/打开电子邮件附件？ [英] How to send/open email attachments from android app?
问题描述
我想以某种方式将一个Android设备上的应用程序的文件发送到另一个设备上的应用程序。这可以以任何方式完成，如果您能告诉我如何通过网络发送或类似的东西，我可以接受建议。
I would like to somehow send a file from my app on one android device to my app on another device. This can be done any which way, and I'm open to suggestions if you can tell me how to send over network or something like that.
目前，我正在将文件发送为电子邮件附件，但是我没有找到任何有关如何做的文档。我需要两件事情才能完成，可以将我的文件（存储在SD卡或设备上的某个位置）作为附件，并将我的应用程序识别为android作为应用程序打开附件与文件扩展名（.lst）
Currently, I'm looking at sending the file as an email attachment, but I haven't found any good documentation on how to do it. I need two things to accomplish this, be able to send my file (stored on sd card or somewhere on device) as an attachment, and have my app recognized by android as the app to open an attachment with the file extention (.lst).
任何想法？
如果这些文件有所作为，这些文件都将是相当小的xml文本文件。
The files will all be fairly small xml text files if that makes a difference.

附件

正如撰写这里，你可以尝试：
As is written up here, you could try:
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
sendIntent.putExtra(Intent.EXTRA_STREAM, ...);
sendIntent.setType(...);
其中第一个省略号是您选择的文件的路径，第二个省略号是合适的MIME类型。
where the first ellipsis is the path to your chosen file and the second ellipsis is a suitable MIME type.
，并将我的应用程序确定为android
作为应用程序打开附件，
文件扩展名（。 lst）
and have my app recognized by android as the app to open an attachment with the file extention (.lst)
不要依赖文件扩展名。使用MIME类型。您可以使用意图过滤器设置活动，为您的MIME类型提供 ACTION_VIEW 支持。
Never rely on file extensions. Use MIME types. You can set up an activity with an intent filter that offers ACTION_VIEW support for your MIME type.
