Android Image Sharing to ImageShack Site

Question

I am developing a android app. In this app need to upload image to imageShack site using their api.

Here "sourceFileUri" is image file path which come from sdcard of the device.It shows Outh or dev Key is invalid.. Please can anyone help me to find out the error. Advanced Thanks.

private void goForUpload(final String sourceFileUri)
{
    if (!SharedPreferencesHelper.isOnline(con))
    {
        return;
    }

    pDialog = ProgressDialog.show(this, "Please wait...", "Loading...",false, false);

    final Thread d = new Thread(new Runnable() 
    {
        @Override
        public void run() {

            String upLoadServerUri = " http://www.imageshack.us/upload_api.php";

            String fileName = sourceFileUri;

            File sourceFile = new File(sourceFileUri);

            Log.w("file name are...", "" + sourceFile);
            if (!sourceFile.isFile()) {
                Log.e("uploadFile", "Source File Does not exist");

dev Key is invalid -> are you sure you dev key of ImageShack is valid? — Tobrun, Dec 07 '12 at 14:51
Yes, Because i can upload image using this api key by browser. — Wasir, Dec 08 '12 at 05:31
12-08 11:31:14.417: W/Respone(9988): 12-08 11:31:14.417: W/Respone(9988):** You must provide a valid auth token or dev key. see http://code.google.com/p/imageshackapi/** 12-08 11:31:14.417: W/Respone(9988): — Wasir, Dec 08 '12 at 05:33
Where you able to figure this out? I tried implementing your code and solution below. I had to comment out all the HttpRequest stuff because it was invalid. So I couldn't read my response text. But I was able to submit and received response code 200, however the pictures never make it to the sight. Very frustrating. Any tips would be appreciated — BriCo84, May 21 '13 at 03:43

First Issue is the order you have your form-data parts:

            dos.writeBytes("Content-Disposition: form-data; name=\"key\""+ lineEnd);
            dos.writeBytes(lineEnd);
            dos.writeBytes("xxxxxxxxxxxxxxxxxx");
            dos.writeBytes(lineEnd);
            dos.writeBytes(twoHyphens + boundary + lineEnd);

            //for image
            dos.writeBytes("Content-Disposition: form-data; name=\"fileupload\";filename=\""+ fileName + "\"" + lineEnd);
                dos.writeBytes("Content-Type: image/jpeg" + lineEnd);
                dos.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);
            dos.writeBytes(lineEnd);
            //dos.writeBytes(twoHyphens + boundary + lineEnd);

Second issue (when I tried) was that image type was invalid, so I added the content-type as seen above. And you didn't need the boundary before writing the file contents.
