android upload image using MultipartEntity

Question

I'm trying to upload an image using the following code:

  HttpClient httpClient = new DefaultHttpClient();

            HttpPost httpPost = new HttpPost(
                    "http://konsole-data.de/uploadtest/upload.php");

            MultipartEntity multiPart = new MultipartEntity();
            multiPart.addPart("picture", new FileBody(new File(path)));

            httpPost.setEntity(multiPart);
            try {
                HttpResponse res = httpClient.execute(httpPost);

                            Toast.makeText(getApplicationContext(),res.toString(),
                        Toast.LENGTH_LONG).show();
            } catch (ClientProtocolException e) {

                e.printStackTrace();
            } catch (IOException e) {

                e.printStackTrace();
            }

path is a String which identifies the image like /mnt/sdcard/DCIM/12712.jpg The connection works BUT no image is uploaded to the server, you can see a debug file here: http://konsole-data.de/uploadtest/data/20121214-144802-.dbg
What am doing wrong?

You should probably specify the HttpMultipartMode, and the MIME type of the file (but this is not necessary i think):

MultipartEntity multipart = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

FileBody bin = new FileBody(new File(path), "image/jpeg");
multipart.addPart("picture", bin);

EDIT:

You should also check if you use the right path. Instead of creating the File object as an anonymous inner class:

File file = new File(path);
if(file.exists()){
    FileBody bin = new FileBody(file, "image/jpeg");
    multipart.addPart("picture", bin);
} else {
    Log.w(YourClass.class.getSimpleName(), "File " + path + " doesn't exist!");
}

just added that.. Still can't get the image uploaded: POST: a:0:{} FILES: a:0:{}

The code seems ok. I use the same method to upload pictures in one of my projects. Are you sure that you have the right path for the image?

Droidman Over a year ago

yep, I used Toast to check that. Path was mnt/sdcard/DCIM/Camera/162533.jpg

Adam Monos Over a year ago

That path is wrong. It's '/mnt/sdcard/...'. You should check with File.exists() if you are looking at the right places.

thanks. The file exists, I forgot to say that I use the same path to create an image preview in the same activity, but I still can't manage the upload.. POST: a:0:{} FILES: a:0:{} Can the reason be that the php script cant handle the file correctly? Thought when I select an image from PC it works fine
