Why can't you convert your bitmap into byte array and pass that to your server. Here is the code to send a bitmap to the server?

Please do these stuffs in AsyncTask.

public class UploadPicture extends AsyncTask<Void, Void, Void> {

    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        // show your progress bar

    }

    @Override
    protected Void doInBackground(Void... params) {
        // TODO Auto-generated method stub

        // wrap up all your upload code here..

        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        // TODO Auto-generated method stub
        super.onPostExecute(result);
        // stop your progress bar
    }
}

Call this class after checking your boolean :

 if(AutoUploadPic)
{
new UploadPicture().execute();
}
else
{
// Your code here..
}

// do the following in the doInBackground Class :

    try {
    ByteArrayOutputStream bos = new ByteArrayOutputStream();

// Preview_bitmap is the one you need to send to the server. I'm compressing here and sending this to server:

    preview_bitmap.compress(CompressFormat.JPEG, 100, bos);
    byte[] data = bos.toByteArray();

    HttpClient httpClient = new DefaultHttpClient();

// constant.uploadImagesAPI is the your server URL :

    HttpPost postRequest = new HttpPost(Constant.uploadImagesAPI
            + Constant.mDeviceID);

    ByteArrayBody bab = new ByteArrayBody(data, ".jpg");
    MultipartEntity reqEntity = new MultipartEntity(
            HttpMultipartMode.BROWSER_COMPATIBLE);
    reqEntity.addPart("image", bab);
    postRequest.setEntity(reqEntity);
    HttpResponse response = httpClient.execute(postRequest);
    BufferedReader reader = new BufferedReader(new InputStreamReader(
            response.getEntity().getContent(), "UTF-8"));
    String sResponse;
    StringBuilder mUploadResponse = new StringBuilder();

    while ((sResponse = reader.readLine()) != null) {
        mUploadResponse = mUploadResponse.append(sResponse);
    }

    JSONObject mUploadResponseObject = new JSONObject(
            mUploadResponse.toString());

    mUploadResponseObject.getJSONArray("response");

    try {
        JSONArray jsonArray = mUploadResponseObject
                .getJSONArray("response");
        for (int i = 0; i < jsonArray.length(); i++) {
            uploadStatus = jsonArray.getJSONObject(i)
                    .getJSONObject("send").getString("message");
            uploadPhotoID = jsonArray.getJSONObject(i)
                    .getJSONObject("send").getString("id");
            Constant.imageUploadedFlag = true;
        }
    } catch (Exception e) {
        serverUploadException = true;

    }

} catch (Exception e) {

}

// PHP code :

   $to = $_REQUEST['deviceid'];
            //$timestamp = $_REQUEST['timestamp'];
            $path=PATH.'upload/';
            //$path1=PATH.'newupload/';
            //$name = $_FILES['image']['name'];
            //$str=explode(".",$name);
            //$imname=$str[0];
            $filename=upload::save($_FILES['image']);                   
            $file_name1= basename($filename);
            $docroot= $_SERVER['DOCUMENT_ROOT'];    
            //$root=$docroot.'/newupload/';
            $roots=$docroot.'/upload/';
            $url = $path.$file_name1;   
                        $send = $this->api->upload_images($to,$url);
                    if($send)
                                {



                                         $json_response[] = array("send" => 
                                               array("id"=> $send,
                                            "message"=>"Message Sent Successfully",
                                             "status"=>1));
                                                             }  
                                                              echo json_encode(array ('response'  =>$json_response));


        break;
