Android: How do I attach a temporary, generated image to an email?

Question

I have a programmatically generated image that I want to send as an attachment via the ACTION_SEND and EXTRA_STREAM method.

But how do i do

Answer 1

I've just run into exactly the same issue (wanting to attach a text file in my case). If you look in the Android log, the reason for it is:

02-28 21:01:28.434: E/Gmail(19673): file:// attachment paths must point to file:///mnt/sdcard. Ignoring attachment file:///data/data/com.stephendnicholas.gmailattach/cache/Test.txt

As a workaround (as mentioned by HRJ), you can use a ContentProvider to provide access to files in your application's internal cache so that Gmail can attach them. I've just written up a blog post on how to do it.

Hopefully that's of some help :)
