Trying to attach a file from SD Card to email

问题:

I am trying to launch an Intent to send an email. All of that works, but when I try to actually send the email a couple \'weird\' things happen.

here is code

Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType(\"image/jpeg\");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, \"Photo\");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(\"file://sdcard/dcim/Camera/filename.jpg\"));
sendIntent.putExtra(Intent.EXTRA_TEXT, \"Enjoy the photo\");
startActivity(Intent.createChooser(sendIntent, \"Email:\"));

So if I launch using the Gmail menu context It shows the attachment, lets me type who the email is to, and edit the body & subject. No big deal. I hit send, and it sends. The only thing is the attachment does NOT get sent.

So. I figured, why not try it w/ the Email menu context (for my backup email account on my phone). It shows the attachment, but no text at all in the body or subject. When I send it, the attachment sends correctly. That would lead me to believe something is quite wrong. Do I need a new permission in the Manifest launch an intent to send email w/ attachment? What am I doing wrong?

Also getting the same problem

Code:

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
    emailIntent.setType(\"image/jpeg\");
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] 
    {\"[e-mail]\"}); 
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, 
    \"Test Subject\"); 
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, 
    \"go on read the emails\"); 
    Log.v(getClass().getSimpleName(), \"sPhotoUri=\" + Uri.parse(\"file:/\"+ sPhotoFileName));
    emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(\"file:/\"+ sPhotoFileName));
    startActivity(Intent.createChooser(emailIntent, \"Send mail...\"));

From adb logcat:

V/DumbDumpersMain( 3972):   sPhotoUri=file://sdcard/DumbDumpers/DumbDumper.jpg
I/ActivityManager(   56):   Starting activity: Intent { action=android.intent.action.CHOOSER comp={android/com.android.internal.app.ChooserActivity} (has extras) }
I/ActivityManager(   56):   Starting activity: Intent { action=android.intent.action.SEND type=jpeg/image flags=0x3000000 comp={com.google.android.gm/com.google.android.gm.ComposeActivityGmail} (has extras) }
I/ActivityManager(   56):   Starting activity: Intent { action=android.intent.action.SEND type=jpeg/image flags=0x2800000 comp={com.google.android.gm/com.google.android.gm.ComposeActivity} (has extras) }
D/gmail-ls(  120):      MailProvider.query: content://gmail-ls/labels/[e-mail](null, null)
D/Gmail   ( 2507):      URI FOUND:file://sdcard/DumbDumpers/DumbDumper.jpg

Looks like the email provider is attaching a 0 length file. When I check the filesystem the file is there and correct. The code which creates the image file is well finished prior to the attempt to email it.

Anyone fixed this without magic reboots (I\'ve already tried that)?

Update

Path for me should have been

file:///sdcard/DumbDumpers/DumbDumper.jpg

you need the extra / as this points to the root directory, i.e.:

file:// + /sdcard/DumbDumpers/DumbDumper.jpg

combined as

file:///sdcard/DumbDumpers/DumbDumper.jpg

In the above snippet you need:

emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(\"file://\"+ sPhotoFileName));

I hope this helps. It took me ages to debug.

Just a little remark from my side. I\'ve been having the same issues with GMail, but somehow it seems to work when I store the file in question on the SD card first and retrieve it from there, rather than from the assets. So my code is the following:

Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_SUBJECT, \"Title\");
i.putExtra(Intent.EXTRA_TEXT, \"Content\");
i.putExtra(Intent.EXTRA_STREAM, uri);
i.setType(\"text/plain\");
startActivity(Intent.createChooser(i, \"Send mail\"));

and here,

uri = Uri.fromFile(new File(context.getFilesDir(), FILENAME));

does not work, whereas

uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), FILENAME));

does.

回答3:

instead of \"Uri.parse\" use \"Uri.fromFile(new File(Environment.getExternalStorageDirectory(),\"file name\"))\"

Environment.getExternalStorageDirectory() - path to SDcard or any other external storage

It appears that this is actually correct, not sure what was happening, but after a reboot it started working :/

    Intent i = new Intent(Intent.ACTION_SEND);
    i.setType(\"message/rfc822\");
    i.putExtra(Intent.EXTRA_EMAIL  , new String[]{\"[e-mail]\"});
    i.putExtra(Intent.EXTRA_SUBJECT, \"Data from app\");
    i.putExtra(Intent.EXTRA_TEXT   , \"experience number x\");
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

    Uri uri = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), \"filename.txt\"));
    i.putExtra(Intent.EXTRA_STREAM, uri);
    startActivity(Intent.createChooser(i, \"Send email...\"));

I got the same problem and looked everywhere for a solution. Finally I solved it by finding an open source app that worked out of the box and looked at how they did it. The code is rather long so I won\'t quote it here but post a link. Look at the sendEmail function in line 449

http://rehearsalassist.svn.sourceforge.net/viewvc/rehearsalassist/android/trunk/src/urbanstew/RehearsalAssistant/SessionPlayback.java?revision=94&view=markup

I refactored my code to be similar, and now it works. I hope this will help others in the same situation.

回答7:

From RFC 1738 section 3.10:

A file URL takes the form:

   file://<host>/<path>

where host is the fully qualified domain name of the system on which the path is accessible, and path is a hierarchical directory path of the form directory/directory/.../name.

So it\'s file:///path/from/root just like http://host/path/from/root because there\'s an implicit \'localhost\' between the second and third slash. But as mentioned above, use Uri.FromFile() to build it.

回答8:

I had the same symptoms. In my case it was because I was initially saving the attachment with the permissions MODE_PRIVATE. As soon as I changed it to MODE_WORLD_READABLE it seems GMail was then able to access the file and send the attachment properly.

It\'s work perfectly for me: On this solution the Nicolas create one copy inside Cache folder and here gmail intent has access! http://stephendnicholas.com/archives/974

public void sendMail(String path) {
        Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
        new String[] {AppConstant.server_mail});
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
        \"IBPS ERROR Mail\");
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,
        \"This is an autogenerated mail from IBPS app\");
        emailIntent.setType(\"image/png\");
        Uri myUri = Uri.parse(\"file://\" + path);
        emailIntent.putExtra(Intent.EXTRA_STREAM, myUri);
        startActivity(Intent.createChooser(emailIntent, \"Send mail...\"));
        }

Also try adding Intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); This helped with my issue.

I have got solution on this after 4 days, Please note following points while giving path to File class in Android(Java):

1) Use path for internal storage String path=\"/storage/sdcard0/myfile.txt\";

2) path=\"/storage/sdcard1/myfile.txt\";

3) mention permissions in Manifest file.

<uses-permission android:name=\"android.permission.WRITE_EXTERNAL_STORAGE\" />
<uses-permission android:name=\"android.permission.READ_EXTERNAL_STORAGE\" />

4) First check file length for confirmation.

5) Check paths in ES File Explorer regarding sdcard0 & sdcard1 is this same or else......

e.g.

File file=new File(path); 
long=file.length();//in Bytes

Send an email with an attachment: (By docs)

Intent emailIntent = new Intent(Intent.ACTION_SEND); emailIntent.setType(HTTP.PLAIN_TEXT_TYPE);

emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[] {\"[e-mail]\"});

emailIntent.putExtra(Intent.EXTRA_SUBJECT, \"Email subject\"); emailIntent.putExtra(Intent.EXTRA_TEXT, \"Email message text\"); emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(\"content://path/to/email/attachment\"));

// You can also attach multiple items by passing an ArrayList of Uris
