Hi,
I'm trying to POST a jpeg image as part of a multipart message, and
keep getting errors saying the file is incorrect.
The jpeg data is retrieved from the photo store using its URI. This
bit seems to work fine.
All the other parts of the multipart message also work fine, and I
know that there isn't a problem with the POST script.
Unfortunately the error message isn't very descriptive - it just says
"Please upload a JPEG image only".
I think the problem is something to do with the conversion from bitmap
to jpeg to ByteArrayPartSource. Should I use some method other than
FilePart for uploading jpegs?
My code is below...
Thanks
Anna
--------------------------------
method = new PostMethod(url);
try {
Bitmap bitmap;
ByteArrayOutputStream bytes;
byte[] imageData = null;
HttpClient client = new HttpClient();
client.getHttpConnectionManager().getParams()
.setConnectionTimeout(5000);
//Get photo from URI
bitmap =
android.provider.MediaStore.Images.Media.getBitmap(
getContentResolver(), uri);
bytes = new ByteArrayOutputStream();
//Compress to jpeg
bitmap.compress(Bitmap.CompressFormat.JPEG,
100, bytes);
imageData = bytes.toByteArray();
//length is not null, so I know there
is something there
Log.d(LOG_TAG, "len of data is " +
imageData.length + " bytes");
Part[] parts = { new StringPart("name", name),
new StringPart("email", email),
new FilePart("photo", new
ByteArrayPartSource("photo",
imageData))
};
method.setRequestEntity(new
MultipartRequestEntity(parts,
method.getParams()));
client.executeMethod(method);
responseString =
method.getResponseBodyAsString();
method.releaseConnection();
Log.e("httpPost", "Response status: " +
responseString);
textMsg.setText(" Response: " + responseString);
} catch (Exception ex) {
Log.v(LOG_TAG, "Exception", ex);
return false;
} finally {
method.releaseConnection();
}
