Question

我可以使用来自here和here的DK代码示例发送彩信。我想把图像放到MMSPart类中。我认为mimetype将是“image / jpeg”（纠正我，如果我完全关注它），但如何将图像放入Data参数 - 我是否需要将图像读入fileInputStream或bitmapfactory并设置它的.Data值？

更新 - 尝试了asahi的代码，我想我越来越近，但现在我收到内存不足的错误。这是来自logcat的信息..

- 首先是这个 -

Out of memory on a 3602732-byte allocation.

- 然后这个 -

感谢您的帮助。

您可以这样做：

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();

使用httpConnection发送MMS - 将图像添加到PDU
