从 android 调用端点时出现 java.lang.VerifyError

Question

我有一个应用程序引擎连接的 Android 应用程序。服务器是java的。我正在测试后端的登录网络服务。在代码调用端点发送登录信息的地方，我遇到异常。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之处。这只是一个带有数据的 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

我认为这是我需要理解的。

无论如何，这是整个跟踪:

编辑:

要设置凭据，我只需遵循模板即可:

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;
    }

看起来问题出在 google-play-service.jar 上。我一直通过构建路径添加它。现在我手动将其添加到 libs 文件夹中，这个问题就消失了。感谢大家的评论。给大家点赞。
