Though I try with the following code snippet(pasted below) I get a 200OK but 
still the doc(text/plain) is NOT updated from my local phone.

            try {
                HttpRequest requestPost = transport.buildPutRequest();
                requestPost.url = DocsUrl.forUploadingFile(editLink);
                ((GoogleHeaders) requestPost.headers).setSlugFromFileName("books1.xml");
                InputStreamContent content = new InputStreamContent();
                File file = new File("//sdcard/books.xml");
                content.setFileInput(file);
                content.type = "text/plain";
                content.length = file.length();
                System.out.println("Length of the file = "+content.length);
                requestPost.content = content;

                HttpResponse  responseUpload = requestPost.execute();
                System.out.println("Uploading code = "+responseUpload.statusCode);

            } 
            catch (FileNotFoundException e) {
                e.printStackTrace();
            }
            catch (ClientProtocolException e) {
                System.out.println("Client Protocol Exception");
            }
            catch (IOException e) {
                handleException(e);
            }
