Android 尝试将新对象插入app engine数据库时出错

这是我第一次尝试让应用程序引擎工作，所以也许我只是错过了某个地方的一个步骤，但我正在尝试像这样将内容插入到应用程序引擎数据库中

Builder endpointBuilder = new Manufacturerendpoint.Builder(AndroidHttp.newCompatibleTransport(),new JacksonFactory()
    , new HttpRequestInitializer() {
        public void initialize(HttpRequest httpRequest) { }
    });

    Manufacturerendpoint manufacturer = CloudEndpointUtils.updateBuilder(endpointBuilder).build();



    String[] manufacturers = this.getResources().getStringArray(R.array.manufacturers);
    ContentValues v = new ContentValues();
    ContentValues val = new ContentValues();
    for(int i = 0; i < manufacturers.length; i++){
        Manufacturer manu = new Manufacturer();
        manu.setManufacturerName(manufacturers[i]);
        manu.setManufacturerID(i);
        try{
            Manufacturer result = manufacturer.insertManufacturer(manu).execute();
            Log.d("TAG", "TAG");
        }catch(Exception e){
            e.printStackTrace();
        }

我还有别的事要做吗？我将此用作参考

当Google Cloud Endpoints处于trusted tester阶段时，您需要在部署应用程序之前将其列入白名单。要被列入白名单，您必须申请并被接受。目前，我们已经降低了接受率，因此您可能不会被接受，或者在长时间延迟后可能会被接受

正如您所看到的，本地开发应该可以正常工作。

与此同时，app engine是否提供了其他解决方案，我可以在这些解决方案中存储我的应用程序数据？我现在需要做的就是让所有用户在每次启动应用程序时从中央数据库中提取一个项目列表，并相应地更新本地数据库。或者云端点是目前唯一的选择吗？您可以通过自己编写来复制端点的大部分功能，但这需要付出更多的努力。我建议等待端点的发布。
