you must use

aIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM,theUris);
aIntent.setType(theOverallMIMEtype);

Here is the code you need to create an emailIntent that contains multiple attachments.

<pre><code>public static void email(Context context, String emailTo, String emailCC,
 String subject, String emailText, List&lt;String&gt; filePaths)
{
 //need to "send multiple" to get more than one attachment
 final Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
 emailIntent.setType("text/plain");
 emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, 
 new String[]{emailTo});
 emailIntent.putExtra(android.content.Intent.EXTRA_CC, 
 new String[]{emailCC});
 emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject); 
 emailIntent.putExtra(Intent.EXTRA_TEXT, emailText);
 //has to be an ArrayList
 ArrayList&lt;Uri&gt; uris = new ArrayList&lt;Uri&gt;();
 //convert from paths to Android friendly Parcelable Uri's
 for (String file : filePaths)
 {
 File fileIn = new File(file);
 Uri u = Uri.fromFile(fileIn);
 uris.add(u);
 }
 emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
 context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
}
</code></pre>

blocks|key|1113275|text|ACTION_SEND_MULTIPLE应该是操作|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1113276|然后是emailIntent.setType("text/plain");|1113277|然后是：|1113278|ArrayList<Uri>+uris+=+new+ArrayList<Uri>();

emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM,+uris);
startActivity(emailIntent);|code-block|syntax|javascript|1113279|这对我很有效。|1113280|entityMap^0|0|K|0|3|Y|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|V|8|@$9|W|A|X|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|Y|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|Z|8|@]|D|@]|E|$M|N]]|$1|O|3|P|5|6|7|10|8|@]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|R|$]]

<code>ACTION_SEND_MULTIPLE</code> should be the action

and then <code>emailIntent.setType("text/plain");</code>

followed by:

<pre><code>ArrayList&lt;Uri&gt; uris = new ArrayList&lt;Uri&gt;();
String[] filePaths = new String[] {"sdcard/sample.png", "sdcard/sample.png"};
for (String file : filePaths)
{
 File fileIn = new File(file);
 Uri u = Uri.fromFile(fileIn);
 uris.add(u);
}
emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(emailIntent);
</code></pre>

This works for me.

blocks|key|1328453|text|虽然这是一个老帖子，但当它显示在谷歌搜索的顶部时，我想添加一个小提示来使它完整，因此我偶然发现了它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1328454|有必要使附件对于邮件活动可读，否则它们将不会被附加。所以你得找个地方打个电话|1328455|fileIn.setReadable(true,+false)|code-block|syntax|javascript|1328456|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|L|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|M|8|@]|9|@]|A|$G|H]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Although this is an old thread, but as it is shown on top on google searches i want to add a small hint to make it complete, hence I stumpled upon it.

It is necessary to make the attached files readable for the mail activity, otherwise they will not be attached. So you have to call somewhere

<pre><code>fileIn.setReadable(true, false)
</code></pre>

blocks|key|1113389|text|对于多个附件，请使用PutParcelableArrayListExtra(Intent.ExtraStream,+uris)，其中uris变量是一个List<IParcelable>().，下面是一个示例：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1113390|var+email+=+new+Intent(Intent.ActionSendMultiple);
++++email.SetType("text/plain");
++++email.PutExtra(Intent.ExtraEmail,+new+string[]{emailTo});
++++email.PutExtra(Intent.ExtraCc,+new+string[]{emailCC});

++++var+uris+=+new+List<IParcelable>();
++++filePaths.ForEach(file=>+{
++++++++var+fileIn+=+new+File(file);
++++++++var+uri+=+Android.Net.Uri.FromFile(fileIn);
++++++++uris.Add(uri);
++++});

++++email.PutParcelableArrayListExtra(Intent.ExtraStream,+uris);

++++context.StartActivity(Intent.CreateChooser(email,+"Send+mail..."));|code-block|syntax|javascript|1113391|希望这能有所帮助;)|1113392|entityMap^0|A|1H|23|K|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|V|8|@]|D|@]|E|$]]]|N|$]]

For multiple attachments use <code>PutParcelableArrayListExtra(Intent.ExtraStream, uris)</code>where uris variable is a <code>List&lt;IParcelable&gt;().</code>
Here's an example: 

<pre><code>var email = new Intent(Intent.ActionSendMultiple);
 email.SetType("text/plain");
 email.PutExtra(Intent.ExtraEmail, new string[]{emailTo});
 email.PutExtra(Intent.ExtraCc, new string[]{emailCC});

 var uris = new List&lt;IParcelable&gt;();
 filePaths.ForEach(file=&gt; {
 var fileIn = new File(file);
 var uri = Android.Net.Uri.FromFile(fileIn);
 uris.Add(uri);
 });

 email.PutParcelableArrayListExtra(Intent.ExtraStream, uris);

 context.StartActivity(Intent.CreateChooser(email, "Send mail..."));
</code></pre>

Hope this helps ;)

I've been working on Android program to send email with an attachment (image file, audio file, etc) using Intent with <code>ACTION_SEND</code>. The program is working when email has a single attachment. I used <code>Intent.putExtra(android.content.Intent.EXTRA_STREAM, uri)</code> to attach the designated image file to the mail and it is working fine, the mail can be delivered through the Gmail. However, when I tried to have multiple images attached to the same mail by calling <code>Intent.putExtra(android.content.Intent.EXTRA_STREAM, uri)</code> multiple times, it failed to work. None of the attachment show up in the email. 

I searched the SDK documentation and Android programming user group about email attachment but cannot find any related info. However, I've discovered that there's another intent constant <code>ACTION_SEND_MULTIPLE</code> (available since API level 4) which might meet my requirement. Based on SDK documentation, it simply states that it deliver multiple data to someone else, it works like <code>ACTION_SEND</code>, except the data is multiple. But I still could not figure out the correct usage for this command. I tried to declare intent with <code>ACTION_SEND_MULTIPLE</code>, then call <code>putExtra(EXTRA_STREAM, uri)</code> multiple times to attach multiple images, but I got the same erroneous result just like before, none of the attachment show up in the email. 

Has anyone tried with <code>ACTION_SEND_MULTIPLE</code> and got it working with multiple email attachment?
