Question

我是Android的新手，我在实施推送通知时遇到了问题。

正如我在阅读的教程中所述，我在c2dm中注册并获得了Auth令牌，然后在UrbanAirShip中注册，包xxxx，获得了app密钥和秘密。

我的项目团队最初使用的是API 2.1，当时我在设备和模拟器中通过氦传输获得了AppId。

然后我们将API更改为2.2，那时我再次在c2dm中注册了另一个发件人ID，获得了Auth令牌，并再次在UrbanAirShip中注册了新帐户，得到了关键和秘密。

对于通过c2dm传输的前几次尝试，我得到了AppId，然后我得到了null，无论是在设备还是模拟器中都有错误，如下所示，

我不知道出了什么问题，无论是API级别的更改，还是c2dm中的多个发件人ID注册，还是UrbanAirShip中针对相同包名称或多次卸载的多次注册。我已经添加了Manifest文件和Application的oncreate方法，请指导我回到AppId。

Answer 1

在模拟器中运行时会出现问题。您需要在设备中运行它（并且应该设置Gmail帐户 - 否则会出现错误）。此外，它应该是2.2+。推送仅支持2.2+设备。将minSDK版本更改为2.2并在设备中尝试。它会起作用。

Answer 2

您需要确保使用所需SDK的“google api”版本，并且还要拥有一个支持市场的有效Google帐户。这是c2dm的要求。

c2dm将Application Id返回为null
