Add menu options to email attachments

Please see the requirement below.

For instance, take Astro browser as a template. You might have seen context menu (with menu options such as Open as, Edit, Details and Send), popping up once an item in the list is selected. I want to implement a similar context menu, with different options, when user taps an email attachment irrespective of email clients. Ideally an option would be 'send via bluetooth', allowing the user to send the attachment straight away.

I looked for suitable APIs. However, there isn't any. This made me think about native programming. I a开发者_开发问答m pretty new to those stuffs.

Could anyone throw some inputs on how to proceed?

Thanks in advance!

That is not possible, sorry. You are welcome to implement your own mail client with your own context menu, though.
