我正在开发一款使用Syncano将数据发送到Syncano服务器的Android应用程序，但是数据无法发送。我们已经验证了我们发送工作的条件，但它并没有起作用。这里是用于发送数据的活动：

    }

    @Override

        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement

你的发送方法可能如下所示。
当你创建一个对象时，你的结果代码应该是HTTP_CODE_CREATED 201，响应类型为Response<Book>。 当你下载对象时，你的响应代码应该是HTTP_CODE_SUCCESS 200，响应类型为Response<List<Book>>

    @Override
    protected String doInBackground(String... params) {
        // send object to server
        Response<Book> responseCreateObject = syn.createObject(b).send();
        if (responseCreateObject.getHttpResultCode() == Response.HTTP_CODE_CREATED) {
            Log.d(TAG, "Success. Item created.");
        } else {
            Log.d(TAG, "Fail.");
        }

        // get objects from server
        Response<List<Book>> responseGetObjects = syn.getObjects(Book.class).send();
        if (responseGetObjects.getHttpResultCode() == Response.HTTP_CODE_SUCCESS) {
            List<Book> books = responseGetObjects.getData();
            Log.d(TAG, "Success. Items downloaded: " + books.size());
        } else {
            Log.d(TAG, "Fail.");
        }

        return "Executed";
    }

我稍微简化了你的代码，重点放在了 Syncano 连接上，并且它能正常工作！它会在你的 Syncano 实例上创建一个对象。

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_other);

        syncano = new Syncano("<api_key>", "<instance>");
        btn = (Button) findViewById(R.id.crash);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override

                Random rnd = new Random();

                Book book = new Book();
                book.latitude = rnd.nextFloat();

                book.force_x = rnd.nextFloat();
                book.force_y = rnd.nextFloat();
                book.force_y = rnd.nextFloat();

            // get objects from server

            if (responseGetObjects.getHttpResultCode() == Response.HTTP_CODE_SUCCESS) {

            }

            return "Executed";
        }
    }

    @SyncanoClass(name = "ltds")
