Convert string to email app on Android

Question

So, I have som data that I converted to a string. While I found how to attach something from the SD card to the mail, I cannot figure out how to directly convert my string to an attachment application without using the SD card. In case it matters, I read some data from the database, converted it to csv format and now I want to connect it as a csv file.

Greetings

Answer 1

I have the same problem, I am trying to send a file without saving it to the file system. I tried adding uri al stream data additionally:

String fileContent = "File Content"; emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("data://text/plain;base64,"+ _utils.Strings.base64_encode(fileContent))); 

I used my own class to create base64 content, but I think it will also work with: http://developer.android.com/reference/android/util/Base64.html

In this case, it was a success that saw the downloaded file in my mail client.

But there are 2 problems: 1. I do not know how to determine the name for this file 2. An error occurs when I try to send a file and I receive mail without an attachment on the other end.

UPDATE 2015-05-13: The mail application displays the following error for my attachent:

 E/Gmail(11511): java.io.FileNotFoundException: No content provider: data://text/plain;base64, 

I think this means that my phone does not have a user-friendly content provider that can process uris data. So I think that we should create a ContentProvider (see http://developer.android.com/guide/topics/providers/content-provider-creating.html )

And we realize

 openOutputStream(android.net.Uri) 

to return the contents of uri data.

Answer 2

create a temporary file using the file API, and then you can continue and add it as an additional email in intention, like this

 emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(csvFile));
