我有一个与应用引擎连接的android应用。该服务器使用Java。我正在测试后端的Login Web服务。代码在调用端点以发送登录信息的地方，出现异常。我包括整个堆栈跟踪。但根本原因似乎是LoginActivity.java:262：
service.registerUser(request).execute();//service is endpoint
此登录没有什么特别的。这只是带有数据的POST。我不知道如何解释错误行
Caused by: java.lang.VerifyError: com.google.api.client.googleapis.extensions.android.gms.auth.GoogleAccountCredential$RequestHandler
我认为这是我需要了解的。
无论如何，这是整个轨迹：

编辑：
要设置凭据，我只需遵循以下模板：
public static GameApp getService(Context context) {
GoogleAccountCredential credential = GoogleAccountCredential.usingAudience(context, StateValues.AUDIENCE);
GameApp.Builder builder = new GameApp.Builder(
AndroidHttp.newCompatibleTransport(),
new GsonFactory(),
credential);
GameApp service = builder.build();
return service;
}
最佳答案
看来问题出在google-play-service.jar。我一直在通过构建路径添加它。现在，我将其手动添加到libs文件夹中，该问题消失了。谢谢大家的评论。支持所有人。
