我正在尝试使用GoogleAuthUtil.getToken生成可用于获取通知密钥的令牌。
但是，我运行我的应用程序，它崩溃了。
PS：我已经添加了
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
到清单文件
这是我的java代码

答案 0 :(得分：0)
我找到了解决问题的方法。 ：）
我终于认为我只使用 Web应用程序的客户端ID ， 根据谷歌文档
*
要在客户端上生成通知密钥： 在Google Developers Console中打开您的项目。 点击APIS＆amp; AUTH＆gt;证书。 在OAuth下，单击“创建新客户端ID”。 在Create Client ID对话框中，选择Web Application作为应用程序类型，然后单击Create Client ID。 从Web应用程序的客户端ID复制值＆gt;客户ID。此客户ID表示Google帐户
*
我错过了一个重要的东西，即Android应用程序的客户端ID。为了生成新的，请按照以下步骤操作。
1- Open your project in the Google Developers Console.
2- Click APIS & AUTH > Credentials.
3- Under OAuth, click Create new Client ID.
4- In the Create Client ID dialog, select installed Application
5- Choose Android
6 - get the SHA1 KEY from Eclipse as well as the name of your main package. copy and paste values
基本上是Android应用的客户端ID，允许您的应用向Google服务器发出请求。
