Question

我有一个app-engine连接Android应用程序。服务器在java中。我正在测试后端的登录Web服务。代码调用端点发送登录信息的地方，我得到一个例外。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之处。它只是一个带数据的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

我认为这是我需要理解的。

无论如何，这是完整的痕迹：

编辑：

要设置凭据，我只需按照模板进行操作：

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;
    }

看起来问题是google-play-service.jar。我一直在通过构建路径添加它。现在我手动将它添加到libs文件夹中，这个问题就消失了。谢谢大家的评论。向所有人推荐。
