我正在尝试将Azure连接到Android Studios。我已经遵循了Azure上的教程并创建了一个移动的服务。然后，它给了我一些代码添加到我的应用程序，使他们连接。但是，代码抛出了一个我无法理解的异常。我在网上从头到脚找了一遍，找不到答案。我认为这与依赖项或库导入的方式有关（通过将jar文件粘贴到libs文件夹并添加依赖项）。
引发异常的代码（由Azure提供）：

try {
        mClient = new MobileServiceClient(
                "https://atm.azure-mobile.net/",
                "JWjetFMUVaAXzHmqDVqhkkRhTGGjeW70",
                this
        );
        Item item = new Item();
        item.Text = "Awesome item";
        mClient.getTable(Item.class).insert(item, new TableOperationCallback<Item>() {
            public void onCompleted(Item entity, Exception exception, ServiceFilterResponse response) {
                if (exception == null) {
                    // Insert succeeded
                    Toast.makeText(context, "WOOHOO", Toast.LENGTH_LONG).show();
                } else {
                    // Insert failed
                    Toast.makeText(context, "FAILED", Toast.LENGTH_LONG).show();
                }
            }
        });
    }
    catch(MalformedURLException d) {
    }
