i was able to send an MMS using DK's code sample from here and here. I'd like to put an image into the MMSPart class. I think the mimetype will be "image/jpeg" (correct me if I'm totally worng on that), but how to I put an image into the Data parameter - do I need to read the image into a fileInputStream or bitmapfactory and set the .Data value to it?

UPDATE - tried asahi's code and I think I'm getting closer, but now I'm getting an out of memory error. Here is the info from logcat..

--first this--

Out of memory on a 3602732-byte allocation.

--then this--

Thanks for any help.

You can do something like this:

ByteArrayOutputStream os = new ByteArrayOutputStream();
Bitmap b =  Media.getBitmap(getContentResolver(), bitmapUri);

b.compress(CompressFormat.JPEG, 90, os);

mmsPart.Name = fileName;
mmsPart.MimeType = "image/jpeg";
mmsPart.Data = os.toByteArray();

  • Thanks. I gave that a try, but now I'm getting a java.lang.OutOfMemory error. The image I am loading is 70K. I wonder if there is some limitation on the file size for the MMS. I am going to keep trying things. Has this ever worked for you? – jwenn Oct 16 '10 at 14:32
  • yes, the code above is from a working application. Can you post log? – Asahi Oct 16 '10 at 14:44
  • Thanks - I added the log to my question above. – jwenn Oct 16 '10 at 18:50
  • I got it. It was the image size. I resized it down and it worked. – jwenn Oct 17 '10 at 03:25
  • I know this was answered some time ago but did you notice if the images would arrive with a normal size? – zwebie Jan 16 '13 at 10:25
  • as it was answered some time ago... I'd say I did not notice anything abnormal back then. – Asahi Jan 16 '13 at 10:47
  • do you know if there's a limit to the size image I can send in a mms? – zwebie Jan 16 '13 at 11:49

    sometimes operators impose limit on size of attachments. other than that - do not know – Asahi Jan 16 '13 at 13:16
